Stainless steel is the abbreviation of stainless acid-resistant steel, and the type of steel that is resistant to weak corrosive media such as air, steam, and water, or has rust properties, is called stainless steel. Let's take a look at the main components of stainless steel.

What are the main components of stainless steel?1

1. The main component of stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%.

2. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel is low, with a maximum of no more than 1.2%, and the ωc (carbon content) of some steel is even lower than 0.03% (such as 00Cr12).
