AISI 440C/JIS SUS440C martensitic stainless steel plate
Scope of application:
Mainly used for manufacturing bearing parts in corrosive environment and strong oxidation atmosphere without lubrication. 440C has good dimensional stability at high temperature, so it can also be used as corrosion resistant high temperature bearing steel. In addition, it can also be used to manufacture high-quality cutting tools, such as medical scalpels, scissors, nozzles, bearings and so on. The 440C has a low capacity to withstand dynamic loads.
specificity
440: High strength cutting tool steel, slightly higher carbon content, after appropriate heat treatment can obtain high yield strength, hardness can reach 58HRC, belongs to the hardest stainless steel. The most common example is the "razor blade".
Standards:ASTM,JIS,GB,EN(DIN,BS,NF) Or Per as clients’ requires.
