Product Parameters

 

S32750
What material is Super duplex S32750?
Super Duplex 2507 ,UNS S32750, 1.4410, A182 F53
Alloy 1.4410 ( S32750 ) is a super duplex stainless steel supplied in the solution annealed condition. As a super duplex stainless steel, it combines the desirable aspects of both austenitic and ferritic grades. The higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent number (PREN) of >41, providing pitting and crevice corrosion resistance superior to austenitic and duplex stainless steels in almost all corrosive media, and a Critical Pitting Temperature exceeding 50°C.
Supplied in the annealed condition, it achieves yield strengths of 80ksi (550Mpa), greater than most austenitic and duplex stainless steel grades. It cannot be hardened by heat treatment but can be strengthened by cold working. It also exhibits a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300°C. Alloy 32750 is listed in NACE MR 0175 for sour service and having gained ASME Approval for Pressure Vessel  applications it can be used in a wide variety of applications.

Key Features of S32750

• Very high strength
• Very good resistance to pitting and crevice corrosion
• Excellent resistance to chloride stress corrosion cracking
• Good workability and weldability
