    2507 Duplex Stainless Steel Bar Description

    The 2507 duplex stainless steel bar is crafted from an ultra-duplex stainless steel containing 25% chromium, 4% molybdenum, and 7% nickel. With a high chromium and molybdenum content, 2507 stainless steel exhibits robust corrosion resistance to various acids and exceptional resistance to stress corrosion cracking due to its duplex construction. These bars demonstrate outstanding corrosion resistance in chloride ion-containing environments, making them well-suited for construction and related industries. Additionally, 2507 stainless steel boasts excellent mechanical properties, including high compressive strength, impact strength, and a low coefficient of thermal expansion. As a result, 2507 duplex stainless steel bars are widely utilized in the manufacturing of components for oil and gas, water treatment, fire protection, desalination equipment, mechanical parts, and fuel gas purification equipment.
