Stainless steel is usually divided into

Apr 09, 2020

1. Ferrite stainless steel. Contains 12% to 30% of chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its resistance to chloride stress corrosion is superior to 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. It has good comprehensive performance and is resistant to various media.


3. Austenitic-ferritic duplex stainless steel. It has the advantages of austenitic and ferritic stainless steel, and has superplasticity.


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