What are the common weathering steel plate materials

Material classification of weathering steel plate

1. Ferritic stainless steel: 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: containing more than 18% chromium, it also contains about 8% nickel and a small amount of elements, such as molybdenum, titanium and nitrogen. Good overall performance, resistant to various corrosive media.

3. Austenite stainless steel ferrite duplex stainless steel: it combines the advantages of austenite and ferrite stainless steel, and has superplasticity.

4. Martensitic stainless steel: high strength, but little plasticity and weldability.
