Product Description
A790 S32750 Duplex 2507 Stainless Steel Pipe
Super Duplex 2507 Pipe manufactured to ASTM A789/A790 standards as cold rolled seamless pipe offering exceptional corrosion resistance and mechanical properties.
Product Overview
2507 Super Duplex Stainless Steel Pipe (UNS S32750) is engineered to address corrosion challenges common in 300 series stainless steels. This duplex structure combines the beneficial properties of ferritic alloys—including stress corrosion cracking resistance and high strength—with those of austenitic alloys, such as fabrication ease and corrosion resistance.
Key Advantages
- Enhanced corrosion resistance compared to alternative materials
- Superior tensile and yield strength with excellent ductility
- Outstanding stress corrosion cracking resistance
- Cost-effective solution without compromising quality
- Superior surface finish and precise dimensional accuracy
