2507 Duplex Stainless Steel Bar

2507 duplex stainless steel bar is made of an ultra-duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel. In terms of chemical composition, 2507 stainless steel has relatively high content of chromium and molybdenum, which accounts for its strong corrosion resistance to various acids. Besides, it has excellent resistance to stress corrosion cracking owing to the duplex construction of 2507 stainless steel. 2507 stainless steel bars show excellent corrosion resistance in environments containing chloride ions, which makes it ideal for construction and related industries. In addition, 2507 stainless steel also has excellent mechanical properties including high compressive strength, impact strength and low coefficient of thermal expansion. So 2507 duplex stainless steel bars are widely adopted as manufacturing parts in fields including oil and gas, water treatment, fire protection, desalination equipment, mechanical parts and fuel gas purification equipment.
