ASTM A790 S32750 Super Duplex Stainless Steel Pipe for Chemical Application
This standard is the standard specification for ferritic austenitic stainless steel pipes used in corrosive environments. ASTM A790 specifies the elements and requirements for the manufacturing of seamless and welded pipes, and requires the welding of dual phase steel and super dual phase steel pipes without adding any filler metal.
When using UNS S31803, S32205, S32750, S32760, and S32520 duplex steel materials to produce steel pipes, corrosion testing should be supplemented. The ASTM A790 standard covers steel pipes with diameters ranging from 1/8 "(10.29mm) to 30" (762.0mm) and wall thicknesses ranging from 1.24mm to 12.7mm. Based on ANSI B36.10 for steel pipes, larger diameter steel pipes can be provided according to the A790 standard.
What material is S32750?
S32750 represents a super duplex stainless steel, commonly known commercially as 2507. The microstructure of super duplex steel consists of approximately 50% austenite and 50% ferrite, but its degree of alloying is much higher than that of standard duplex steels such as S31803, especially the chromium, molybdenum and nitrogen content, resulting in higher strength and better corrosion resistance.
