310S Stainless Steel Seamless Pipe with High Temperature and Corrosion Resistance for ASTM A312 Standard Applications
310S stainless steel pipe primarily contains chromium (Cr) and nickel (Ni) elements, with chromium content approximately 25% and nickel content about 20%. This high chromium and nickel content provides excellent oxidation resistance and corrosion resistance. Additionally, it contains small amounts of silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), and other elements.
