Question 2: What is the best knife steel? 420J2: (Cold Stee) Because of its low carbon and high chromium composition, this steel is the best choice for making tough, shock-resistant knife blades, and also has good corrosion resistance and good blade retention. It is an ideal blade material for use in a variety of environments such as high temperatures. Humidity. The high amount of chromium gives it excellent corrosion resistance and makes it a good material for making carry knives and knives that don't require much maintenance.

4Cr13: domestic high quality stainless and acid-resistant steel, low carbon and high chromium steel, widely used in weak corrosive media parts. Medical tools spring. Rolling bearings. Surgical tools. Surgical instruments, excellent corrosion resistance, excellent machinability, comprehensive performance equivalent to 420J2.

425m: 420 series of steel of the modified (Modified) varieties, named 425M, will increase the carbon content to about 0.55%, and add 1% of molybdenum, heat treatment can be violated by a more ideal hardness (HRc58), but retains the 420 series of steel of the good The machinability of 420 series steel is retained, so it is very suitable for use in factory-made cutting tools. The United States Ming's BUCK and GERBER two big knife factory has in the 90's choose 425M as its blade material.

9Cr18: domestic high-quality stainless and acid-resistant steel, chromium content of 18%, carbon content of 0.9%, widely used in automatic lathe parts. Fiber factory machine tools. Corrosion-resistant and wear-resistant parts for petroleum industry. Surgical tools. Surgical instruments, excellent corrosion resistance, excellent processability. The hardness of HRc58 can be achieved after the maturation process.

440-C: American-made high-quality stainless steel, chromium content of up to 16-18%. Originally used in surgical knives and the marine industry, corrosion resistance and z-resistant ability is excellent; strong toughness. Now more widely used in handmade knives and high quality factory-made knives. Carbon content of about 1% (440 system divided into A, B, C, and F grade; C grade and F grade carbon content is the highest, and A grade amputation less amputation). After maturing, it can reach the hardness of HRc58.

9Cr18Mo: domestic high quality stainless steel, chromium content of 18%, containing 1% molybdenum, carbon content of 0.9%, mainly used in weak corrosive media parts. Medical tools spring. Rolling bearings. Surgical tools. Surgical instruments, excellent corrosion resistance, excellent processability, after maturation treatment up to HRc58 hardness.

154CM: American made high quality stainless steel, chromium content up to 15%, molybdenum content up to 15%, molybdenum content up to 4%; so it is named 154CM. It is the modern generation of handmade knives of the master R.W. Loverless pioneered the use. It has excellent machinability, corrosion resistance, blade wear resistance and toughness, but is sold at a higher price, so it is only used for handmade knives. The carbon content is about 1.05%, and the hardness can reach HRc60~61 after heat treatment.

ATS-34: Japan's "Hitachi Metals Industry" for the U.S. 154CM and the development of high-quality stainless steel, materials and ingredients and 154CM is similar, but the performance of all aspects of the 154CM standard, and even better, but the price is cheaper, was recognized as one of the best cutting tool steel, has become a handmade and high-quality factory-made tools. It is recognized as one of the best cutting tool steel in the industry and has become the mainstream of handmade and high quality factory-made cutting tools. It is recognized as one of the best cutting tool steel in the industry and has become the mainstream of handmade and quality factory-made cutting tools.

AUS8(8A): Japan's "Aichi Steel" developed a high-quality stainless steel, corrosion resistance, blade damage resistance and toughness of the excellent level, most of them are used in Japan's high-quality cutting tools. AUS steel grade is divided into 10A (carbon content of about 1%), 8A (content of 0.8%) and 6A (carbon content of about 0.6%) three kinds. 8A heat-treated after the HRT, the steel will be used for the cutting tools, and then the steel will be used for the cutting tools. 8A is heat-treated to HRc58~59 hardness.

D2: metal machining wear-resistant tool steel D2, belongs to the air-hardening steel (Air-Hardening steel); is widely used in felling knife or hunting knife sub-production, carbon content of up to 1.5%, chromium content is also as high as 11.5%, heat-treated up to the hardness of HRc60, but the relative Ting exhibition (toughness) is weaker, the ability to withstand is not good, the steel surface is also difficult to make a mirror finish. The surface of the steel is also difficult to make mirror polishing treatment.

Hi-Speed Tool Steel (high-speed tool steel): highly processed into the tool steel, high carbon content, and chromium content is low (about 4%), so the polishing of the surface of the steel luster is darker, heat-treated up to the high hardness of the HRc62, but the resistance of the performance of the less ...... >>

Question 3: What is the difference between 10 steel and 45 steel, which toughness is good 10 steel and 45 steel difference 42crmo4 is an industrial material 42CrMo4 is used in the manufacture of 35CrMo steel requirements than the strength of the forging and tempering cross-section of the larger, such as locomotive traction with the large gears, supercharger transmission gears, rear axle, the load is very large connecting rod and spring clamps, 42CrMo4 is used in the manufacturing of the requirements of the 35 CrMo steel strength and larger forging, such as locomotive traction with large gears, supercharger transmission gears, rear axle, loaded with great and spring clamps, 42CrMo4 can also be used for 2000m below the oil deep well drill pipe joints and salvage tools, etc. 35CrMo is an alloy structural steel (alloy tempered steel) specification number, the steel is mainly used in the manufacture of various machines to withstand impact, bending and torsion, high loads of the important parts of the 35 steel is the national standard of steel is called No. 10 steel and No. 45 steel area

Question 4: do the sword, with the What is the best steel for making swords? Produced from the United States of America's knife manufacturing steel common main: (1) 154CM high-quality stainless steel, which was originally for the production of aero-engine turbine blade material, is the best of the knife material, this high-quality stainless steel containing chromium 15%, containing molybdenum 4%, containing 1.05% of carbon, the hardness value of up to HRc60 ~ 61, and corrosion-resistant, strong toughness, the blade to maintain the period of time is extremely long, but the price is high, so it is only used in the United States! A few elite military and police forces knife production, such as the famous M.O.D company produced special folding knife for SWAT indoor close combat, the blade is selected 154CM high-quality stainless steel; (2) 440 series of high-quality stainless steel, this stainless steel, including A, B, C, F and so on a number of different models, of which 440C and 440F with the highest carbon content. 440 series is the most widely used knife-making materials, of which 440C is the most widely used. Knife material, of which 440C is the original production of surgical knives, the material of choice, also widely used in shipbuilding, 440C contains chromium 16 ~ 18%, carbon content of 1% or so, with acid and alkali corrosion resistance, machinability, toughness, etc., but its hardness is slightly inferior to the 154CM high-quality stainless steel, hardness value can only be achieved HRc58 or so, like the wild camping friends often wear the Spanish! AITOR company produces the jungle king survival knife, is made of 440 steel; (3) 1095 high-carbon steel, although its carbon content of up to 1.03%, but the toughness is still very good, after special processing of its hardness up to HRc60, and the price is moderate, is a high-carbon steel in the boutique in the machining industry is often used in the manufacture of drills and turning tools, and therefore is also known as the tool steel, but the 1095 high carbon steel is not resistant to rust, therefore, the surface of the tool made of its main material is protected by a variety of coatings. World War II, the U.S. Marine Corps used the famous Caba Saber, is made of 1095 high-quality high-carbon steel.

For the world's major steel country, Japan, also produces high-quality knife steel, more common: (1) ATS-34 high-quality stainless steel, its material and main components and the United States 154CM high-quality stainless steel is similar to the performance indicators have reached the standard 154CM, but the price is slightly lower than 154CM, is the first choice of the knife manufacturing industry, high-grade knife production material, the United States SEAL2000 combat knife used by a small number of elite units in the Marine Corps, is made from a block of ATS-34 high-quality stainless steel; (2) AUS high-quality stainless steel, is a widely used in Japanese knives of high-quality stainless steel, which has a corrosion-resistant, good toughness, blade damage-resistant features, according to the different carbon content, AUS is divided into 10A (1% carbon), 8A (carbon) 0.8%), 6A (carbon content of 0.6%) three types of models, the knife is commonly used AUS-8 (8A) quality stainless steel, its hardness after heat treatment can reach HRc59, Japan-made SOG/PE Ⅱ folding knife, the blade material is the use of AUS-8 quality stainless steel; (3) handmade laminates to beat the steel, is the Japanese traditional knife industry commonly used in the production of a knife material, estimated that the process of its Originally from China, it is the use of different hardness and toughness of the steel by carburizing treatment after repeated folding and forging made of a special process steel, which is made of knives with forging patterns left behind the knife body, blade grinding part of the vaguely visible layers of natural patterns, beautiful, of course, the price of knives made of this material is not expensive.

First, the trademark VICTORINOX = the original owner of the "name" + "stainless steel" = VICTORI + INOX;

Second, no matter who wrote or called to ask the plant its stainless steel composition, the results are all felicitous refusal. Now, the good guys have found out and established that the stainless steel for the blades of the factory is supplied by a company called Sandvik;

4. If one calls Sandvik and asks for an answer to the second point, the answer will be "The stainless steel we supply to VICTORINOX is 12C27. The stainless steel is 12C27." But this answer is vague and incorrect.

Fifth, through Sandvik's steel data sheet can be found, 12C27 in the composition of trace elements in the percentage of about 0.59 carbon, about 13.75 chromium, about 0.375 manganese, 0.4 silicon.

Sixth, through metallographic analysis, the stainless steel composition of VICTORINOX's blade is not the 12C27 steel claimed by Sandvik, which has a trace element composition percentage of 0.52 carbon, 15 chromium, 0.45 manganese, 0.6 silicon, and 0.5 molybdenum. The steel was then called INOX (Blade steel o...... >>

Question 5: What is the best steel for kitchen knives? The following steels are recommended:

Tri-chrome steel, hardened in oil to a hardness of 54-56 HRC.

Four chromium steel, after heating expansion and forging, the hardness can reach 56-58 HRC, the steel series features: sharper, rust, toughness, not easy to break brittle, finer grain, easy to resharpen. Or 413MoV series forging steel

Five chrome steel, after oil quenching treatment, the hardness can reach 58-60HRC. the characteristics of this series of steel products: harder and sharper, long-lasting, anti-rust, high toughness.

Composite steel, through the heat treatment quenching, the outer layer due to the use of low-carbon stainless steel material, the hardness value is lower, generally in the HRC48 below. Specifications have three-layer, five-layer composite steel. Composite steel with composite layer protection is not easy to collapse, roll mouth.

Problem six: the best knife is what steel material to do Depending on the use to determine, and there is no such thing as the best steel, steel is one of the heat treatment is also critical

The first floor of the high-speed steel is generally used in industry, civilian knife without high-speed steel are generally 813 440C 154 D2 this type of, and there is no use of tungsten carbide to do knife, tungsten carbide is certainly hard but do knife is indeed a good idea. Certainly hard but do knife is the worst raw material. Hard, but poor toughness, made into a knife size cost high bizarre, blunt themselves can not grind on that hardness can easily grind the oil stone broken, and carbide is generally used in industry Military

Or that there is no best steel, alone that some kind of steel is the top of the steel is biased, any one of the steel can not be at the same time to reach the top of the hardness, toughness, rust resistance, abrasion resistance, grinding, easy to machine properties, each of which is the most important thing to do, and the most important thing is to use carbide.

Steel is a very big problem, this problem is insoluble, for example, do small knife blade length of 15CM under the folding knife at present the best comprehensive consideration of steel is S30V, do kitchen knives 413 is enough to do large machete knife mountain knife is generally the majority of carbon steel, or forging steel, spring steel, etc., and steel is only one side, heat treatment is the soul of the steel, a good heat treatment! Good heat treatment can turn rotten into miraculous. Bad heat treatment will be the top of the steel into scrap iron

This is a lot of learning a lot, I only know a little bit, ask what the best steel and ask what the best knife is no answer. Cutting vegetables when the best kitchen knife, nail clippers when the best nail clippers, chopping people when the best machete, to prevent rust good if the Swiss Army knife is good is this!

Said the best knife The best steel must be delineated to his purpose and scope of use, as well as performance requirements, etc. Otherwise, there is no way to say, said out of the blind Oh look is hearsay, the knife steel and other not yet a basic understanding and scientific knowledge!

Question 7: What is a better material than No. 45 steel? Check the mechanical design manual, look for alloy materials, there are many good materials.

Question 8: What is the best stainless steel material There is no best, only the most suitable. According to the use of the environment, choose the most suitable stainless steel.
