Classification of Stainless Steel According to the Matrix Structure

2021-11-26 Page view : 30 views

1.) Ferritic stainless steel. Containing 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is better than other types of stainless steel.

2.) Austenitic stainless steel. It contains more than 18% chromium, and also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good overall performance, resistant to corrosion by various media.

3.) Austenitic ferritic duplex stainless steel. It has the advantages of austenitic and ferritic stainless steel, and has super plasticity.

4.) Martensitic stainless steel. High strength, but poor plasticity and weldability.
