(1) The role of manganese

Manganese and nickel are both alloying elements that promote the formation of austenite, so it can replace nickel (or part of it),

Nickel is the main alloying element that forms austenite, but the role of nickel can only be fully demonstrated when combined with chromium. If you simply use n

Chromium is a ferrite forming element; chromium can strongly improve the passivation ability of iron. Chromium plays a decisive role in the corrosion resistance

Carbon plays a dual role in stainless steel, namely the beneficial side and the harmful side, depending on the requirements of use.

One is that carbon can redu
