What are the materials of stainless steel?

The stainless steel material bai has the following series:

It can be divided into Cr series (400 series), zhiCr-Ni series (300 series), daoCr-Mn-Ni (200 series), heat-resistant chromium alloy steel (500 series) and precipitation hardening series (600 series).

Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel according to the state of organization. In addition, it can be divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel.

The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, the maximum does not exceed 1.2%, and the ωc (carbon content) of some steels is even lower than 0.03% (such as 00Cr12 ). The main alloying element in stainless steel is Cr (chromium), and only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally contains at least 10.5% of Cr (chromium). Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.
