Stainless steel 1.4000
Food grade stainless steel 1.4000 is the basic stainless steel of the martensitic class with a reduced carbon content. Differs in considerable wear resistance. Hardening is performed by heat treatment.
Specifications
Stainless steel 1.4000 is distinguished by:
– good plasticity;
– an impressive level of toughness;
– excellent corrosion resistance;
– heat resistance. Resistant to the formation of scale, at temperatures up to 700 degrees.
When softened, stainless steel sheet 1.4000 acquires a mixture structure ferritic and carbide phases. When heated to 960-1020 degrees, followed by hardening, using oil or air, martensite is formed, with a hardness that is directly proportional to the proportion of carbon. At the same time, chromium carbides formed in the process perform additional hardening of the stainless steel structure, increasing its wear resistance and hardness.
Applications
Sheet or stainless steel pipe, grade 1.4000, is successfully used where a combination of high resistance to corrosion and significant wear resistance is important. Like in production:
– scissors, knives and other cutting tools;
– turbine and boiler components;
– wear-resistant gaskets and fasteners;
– crockery;
– separation and heat shields;
– different filters and more.
