2507 Duplex Stainless Steel Pipe Description
2507 is an ultra-duplex stainless steel including 25% chromium, 4% molybdenum and 7% nickel. In terms of chemical composition, the chromium and molybdenum content of 2507 stainless steel is relatively high, which leads to its superior corrosion resistance to various acids. The duplex construction of 2507 stainless steel gives it excellent resistance to stress corrosion cracking. Cracks are an inevitable problem in construction and other related fields, and 2507 stainless steel can perform excellent corrosion resistance in an environment containing chloride ions, making it an excellent option for construction and related industries. 2507 stainless steel also has excellent mechanical properties with high compressive strength, impact strength and low coefficient of thermal expansion, which is why it is often put into use in oil and gas industry, and fields such as water treatment, fire protection, desalination equipment, mechanical parts and fuel gas purification equipment.
