Advantages and disadvantages of 440C and 1095 high carbon steel! Ask for help

440-C: American 100 stainless steel, with chromium content as high as 16- 18%. Originally used in surgical tools and shipbuilding industry, it has excellent corrosion resistance and fatigue resistance; Strong toughness.

1095: The highest quality high carbon steel is 1095, and the carbon content reaches 1. 03%, the hardness can reach HRc58-60 after heat treatment, and the toughness is good, but it is not resistant to corrosion.

Extended data:

1095? Introduction of high carbon steel:

1, features: 1095? It is the most common carbon tool steel with moderate toughness and low production cost. After heat treatment, the hardness can reach above 60HRC. However, this kind of steel has low hardenability and poor heat resistance, so it should not be overheated when quenching and heating, and it still keeps fine grains. The toughness is acceptable, the strength and wear resistance are higher than T7-T9, but the hardness is low, the hardenability is still not high, and the quenching deformation is large.

2. Scope of application: This kind of steel has a wide range of uses, and is suitable for manufacturing all kinds of cutting tools with poor cutting conditions, high wear resistance, certain toughness and sharp cutting edges, such as turning tools, planers, drill bits, taps, reamers, dies, milling hand saw blades, etc.
