Product Description
Introduction
440C steel is a martensitic stainless steel. The carbon content is 1.0%, and the chromium content is 16-18%. It has strong rust resistance and is high-quality stainless steel. High strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach 58hrc. It is one of the hardest stainless steels. The most common application example is "razor blade". It is mainly used to manufacture bearing parts working in corrosive environment and unlubricated strong oxidation atmosphere. 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 knives, such as medical scalpels, scissors, nozzles, bearings, etc. 440f: it is a kind of steel to improve the easy cutting performance of 440C steel. It is used for automatic lathe and ordinary alloy steel. It has the characteristics of hardening through quenching. Therefore, a wide range of different mechanical properties can be obtained by selecting brand and heat treatment conditions.
