UNS S32750, also known as Super Duplex Stainless Steel 2507, is a remarkable alloy designed for applications that demand exceptional strength and corrosion resistance. Let’s explore its uses in various industries:
Remember that Super Duplex Stainless Steel S32750 combines the desirable aspects of both austenitic and ferritic grades, making it a versatile choice across different industries.
Stainless steel Super Duplex 2507 is designed to handle highly corrosive conditions and situations were high strength is required. High molybdenum, chromium and nitrogen content in Super Duplex 2507 help the material withstand pitting and crevice corrosion. The material is also resistant to chloride stress corrosion cracking, to erosion corrosion, to corrosion fatigue, to general corrosion in acids. This alloy has good weldability and very high mechanical strength.
S32205 Seamless Duplex Steel Pipe, also known as Duplex 2205, is a nitrogen-enhanced duplex stainless steel that offers a superior combination of high strength and excellent corrosion resistance. Seamless pipes and tubes made from this material are widely used in various demanding industrial applications where standard austenitic stainless steels are inadequate. Its balanced chemical composition and microstructure provide a desirable set of properties that make it a cost-effective solution for many corrosive environments,known for their excellent mechanical strength and durability in demanding environments.① STANDARD: ASTM A789/ ASTM A790/ ASTM A928/ ...② OD RANGE : 6-720 MM③ THICKNESS RANGE: 1-65 MM
