440C steel is a kind of Martensite stainless steel, which belongs to the 440 series of American standard. 440 stainless steel in the American standard has four grades, respectively: 440A, 440B, 440C, 440F (AST A582), domestic stainless steel and its corresponding grades are 9Cr18, 9Cr18Mo, etc.. The rust resistance of 440C stainless steel is very strong, it is high quality stainless steel.
440C is a representative of martensitic stainless steel, can be heat treated to achieve high hardness, heat treated 440C stainless steel hardness is all stainless steel, heat resistant steel in the highest. It is usually used to manufacture bearings, cutting tools, or plastic molds that require high load and high wear resistance under corrosion conditions. This is why the first word associated with typing 440C is often 440C steel knife.
Application of 440C stainless steel
Stainless steel 440C is suitable for manufacturing bearings and bearing parts in corrosive environments and in a strong oxidizing atmosphere without lubrication.
440C has good dimensional stability at high temperature and is not easy to deform, so it can be used as corrosion resistant high temperature bearing steel.
The 440C can be used to manufacture high quality knives, such as medical scalpels, scissors, nozzles, bearings, etc.
440C stainless steel can be replaced by 440F by improving its ease of cutting and then used in automatic lathes or ordinary alloy steel.
But it should be noted that the capacity of 440C stainless steel to bear dynamic load is low, and attention should be paid to the process of use.
