What's the difference between 20 1 stainless steel and 304 stainless steel?
The content of chromium and nickel in 304 stainless steel (0cr 18ni9) is much higher, and the price is much higher than that of 20 1 stainless steel (cr 14ni5mn5). 20 1 stainless steel has low chromium and nickel content and very high manganese content, and its strength is fine, but its corrosion resistance is far less than that of 304 stainless steel.
