440C stainless steel plate is a kind of martensitic stainless steel plate. Carbon content is of 1.0%, while chromium content is between 16-18%. With Strong resistance to rust, it is high quality stainless steel.

Scope of application: 440c stainless steel plate is mainly used in the manufacture of corrosive environment and non-lubricating strong oxidizing atmosphere in the work of bearing parts. 440C stainless steel plate has a good high temperature dimensional stability, and it can also be used as corrosion-resistant high-temperature bearing steel. In addition, it can also be used to manufacture high-quality tools, such as medical scalpels, scissors, nozzles, bearings and so on. 440C stainless steel sheet has the ability to withstand dynamic loads.

440: high-strength cutting tool steel, carbon slightly higher, it can get a higher yield strength after appropriate heat treatment, and its hardness can reach 58HRC, which are the hardest stainless steel column. The most common application example is the "shaving blade". There are three commonly used models: 440A, 440B, 440C, in addition to 440F (easy to process).
