ASTM A928 Class 1 S32750 Duplex Stainless Steel Welded Pipe for Oil and Gas Industry
ASTM A928 is a standard developed by the American Society for Testing and Materials (ASTM), officially known as the "Standard Specification for Ferritic/Austrian (Duplex) Stainless Steel Pipe Electric Fusion Welded with Addition of Filler Metal". This standard covers the manufacturing requirements for duplex stainless steel welded steel pipes and is applicable to corrosive environments such as chemical, marine, oil and gas. S32750 is a grade of duplex stainless steel, corresponding to UNS S32750 (Unified Numbering System), also known as 2507 super duplex stainless steel.
The chemical composition of S32750 duplex stainless steel material is mainly composed of Cr, Ni, Mo, N, and Fe. Among them, Cr can improve the corrosion resistance and oxidation resistance of S32750, Ni can improve the stability and toughness of austenite, Mo helps S32750 resist pitting and crevice corrosion, and N can improve the strength and corrosion resistance of S32750.
