What is ASTM A815 WPS UNS S32750?

  • ASTM A815: This specification covers wrought ferritic, austenitic, and duplex stainless steel fittings for pressure piping applications.
  • WPS: Stands for “Wrought Pipe Fittings – Seamless”.
  • UNS S32750 (Super Duplex 2507): A super duplex stainless steel known for its excellent resistance to pitting, crevice corrosion, stress corrosion cracking, and high mechanical strength.UNS S32750 is the Unified Numbering System designation for Duplex Stainless Steel 2507, a super duplex stainless steel with very high strength and exceptional corrosion resistance.

1.4410 / Alloy 2507 is a SUPER-DUPLEX stainless steel. It contains about 25% chromium, 7% nickel, 3.7% molybdenum, and 0.3% nitrogen.

UNS S32750 is known as a super duplex grade for its Exceptional strength and corrosion resistance. Excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion
