Stainless steel beads are usually produced through a forging process. At this stage, commonly used stainless steel beads are made of 201, 302, 304, 316, 316L, 420 and 440C.
Definition: Steel containing more than 12% chromium that is resistant to chemicals.
Principle: Stainless steel does not rust, but it is not easy to rust. The principle is that by adding chromium elements, a dense chromium oxide layer is formed on the surface of the steel, which can effectively prevent re-contact between the steel and the air, so that oxygen in the air cannot enter the steel, thus preventing the steel from rusting. .
Classification: The 200 series is chromium-nickel-manganese series austenitic stainless steel, the 300 series is chromium-nickel austenitic stainless steel, and the 400 series chromium stainless steel (commonly known as stainless steel) includes martensite and ferrite. In addition, it is also classified based on composition, magnetic permeability, heat treatment hardening and steel grade.
