Can 9cr18mov be made into knives?

9cr18mov belongs to high-quality stainless steel, its strength and sharpness is even more than ATS-34, chromium content is up to 16-18%, you can make knives.

1, Advantages:

9cr18mov is the second most commonly used stainless steel (after ATS-34), but also the earliest stainless steel accepted by the knifemaker, 440C annealing temperature is very low, quenched hardness is high, hardness is usually up to HRC56-58, corrosion resistance is good (magnetic) toughness are very strong.

2, disadvantages:

9cr18mov in grinding, it has the disadvantage of being more viscous, and heating up quickly.

Requirements for stainless steel machining tools

Stainless steel machining tools is mainly to choose the tool angle, it is difficult to process lies in the toughness of the very good, red hardness is high, the wear of the tool to add poly, choose a sharp tool on the good, high-speed steel cutter and tungsten carbide cutter can be, pay attention to the chipbreaking groove and tool angle.

Stainless steel processing requirements of the tool_Requirements for the tool geometry parameters processing of stainless steel, the geometry of the cutting part of the tool, generally should be considered from the front angle, the rear angle of the choice. When choosing the front angle, we should consider the type of chip roll groove, the presence or absence of chamfering and the size of the positive and negative angle of the edge inclination and other factors.

No matter what kind of tool, the machining of stainless steel must be used in a larger front angle. Increase the front angle of the tool can reduce the resistance encountered in the process of chip cutting and clearing out. The choice of the rear angle is not strict, but should not be too small, the rear angle is too small and easy to produce serious friction on the surface of the workpiece, so that the machining surface roughness deterioration, accelerated tool wear.

Requirements for the surface roughness of the cutting part of the tool to improve the surface finish of the cutting part of the tool can reduce the chip formation curl resistance, improve the durability of the tool.
