ASME SA240 ASTM A240 UNS S32900 stainless steel sheetis a hot-rolled or cold-rolled plate from the duplex stainless steel family, combining austenitic and ferritic phases with molybdenum for enhanced corrosion resistance and mechanical strength. 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 550 MPa) and a PREN around 30, offering good resistance to pitting and stress corrosion cracking in chlorides.
Unlike standard austenitic 304 or 316 stainless steels, UNS S32900 stainless steel sheets deliver superior mechanical properties with better resistance to stress corrosion, allowing for thinner sections and material savings while maintaining good 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 S32900 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. Our expertise extends to related duplex grades like sa240/a240 uns s32803 and sa240/a240 uns s31200.

UNS S32900is a duplex stainless steel used in applications requiring high strength and corrosion resistance, such as chemical tanks, pulp digesters, and offshore piping in oil and gas, paper production, and marine sectors. Its duplex structure provides yield strength of 450 MPa, double that of 316, with good pitting resistance (PREN ~30) in chlorides like seawater up to 40°C. Gangsteel supplies ASME/ASTM sheets for structural and piping, with use in fertilizer plants reducing thickness 30% for cost savings. For leaner duplex, see sa240/a240 uns s32101.
UNS S32900outperforms 316L (S31603) with duplex structure for higher yield (450 MPa vs. 205 MPa) and better stress cracking resistance, PREN 30 vs. 24 for moderate chlorides. 316L is more ductile for forming; S32900 saves 30% material in strength-critical. Cost: S32900 15% higher but lighter. Gangsteel recommends for tank upgrades. Equiv: sa240/a240 uns s32906.
Yes, UNS S32900 welds well with GTAW/SMAW using ER2209 fillers; duplex balance requires post-weld anneal 1025°C for full PREN, preheat 100°C, interpass <150°C to retain 40-60% ferrite. ASTM A923 confirms no intergranular. Gangsteel certs for cyclic, thick-plate with 10% less heat input than austenitics. Protocols: sa240/a240 uns s32950.
The density of ASME SA240 ASTM A240 UNS S32900 stainless steel sheet is 7.8 g/cm³ (0.282 lb/in³), typical for duplex, enabling 20% thinner designs vs. austenitics for weight reduction in tanks without strength loss. Gangsteel factors in logistics.
