ASME SA240 ASTM A240 UNS S32101 stainless steel sheetis a hot-rolled or cold-rolled plate from the lean duplex stainless steel family, combining austenitic and ferritic phases with manganese and nitrogen for enhanced strength and corrosion resistance. Specified under ASME SA240 for pressure vessels and ASTM A240 for general corrosion-resistant applications, this grade is annealed for optimal wrought performance in moderately aggressive environments. The duplex microstructure provides high yield strength (over 450 MPa) and a PREN around 26, offering good resistance to pitting and stress corrosion cracking in chlorides.
Unlike standard austenitic 304 or 316 stainless steels, UNS S32101 stainless steel sheets deliver superior mechanical properties at a cost similar to 316, allowing for thinner sections and material savings while maintaining excellent formability and weldability. With a product density of 7.8 g/cm³, these sheets balance lightweight design with robustness, versatile for fabrication into tanks, piping, and structural beams. Gangsteel has exported thousands of tons of ASME SA240 ASTM A240 UNS S32101 stainless steel sheets to clients in Europe, North America, and Asia, ensuring compliance with ISO 9001 and PED certifications for seamless integration into your supply chain.
