ASME SA240 ASTM A240 UNS S35315 stainless steel sheetis a hot-rolled or cold-rolled plate from the high-temperature austenitic stainless steel family, supercharged with chromium and silicon for unparalleled resistance to gaseous corrosion and scaling. Specified under ASME SA240 for pressure vessels and ASTM A240 for general high-temperature applications, this grade is solution-annealed for superior wrought performance in continuous service up to 1200°C. The synergistic 25% Cr and 5% Si create a self-healing, silica-rich chromia layer that repels oxygen, sulfur, and carbon ingress.
Far exceeding 304 or 310 in extreme oxidation, UNS S35315 stainless steel sheets withstand carburizing and sulfidizing atmospheres where others erode rapidly, delivering decades of service in cyclic extremes. With a product density of 8.0 g/cm³, it offers efficient thermal conductivity for furnace baskets, thermocouple sheaths, and burner parts. Gangsteel has exported thousands of tons of ASME SA240 ASTM A240 UNS S35315 stainless steel sheets to clients in Europe, North America, and Asia, fortified by ISO 9001 and PED certifications for seamless supply integration.

UNS S35315is a high-Cr/Si austenitic stainless steel for extreme high-temperature oxidation like sintering furnace belts in electronics manufacturing, pyrolysis retorts in plastic recycling, and waste incinerator grates where resistance to 1200°C air/SO2 is paramount. Its 24-28% Cr and 4-6% Si forge a self-renewing silica-chromia scale, outlasting 314 by 50% in cyclic sulfidizing, preventing carburization in carbon-rich gases. Gangsteel supplies ASME/ASTM sheets for vessels and kiln fittings, with use in cement rotary kilns boosting uptime 45%. Milder: sa240/a240 uns s32101.
UNS S35315outshines 314 (S31400) with higher Si (4-6% vs. 1.5-3%) for viscous scale in 1100-1200°C SO2, plus Ni (30-35% vs. 19-22%) for austenite stability—PREN ~25 both, but S35315 resists sulfidation 2x longer (ASTM G28). 314 suits 1000°C air; S35315 carburizing wastes. Cost: S35315 20% higher for Si/Ni. Gangsteel picks for incinerators. Equiv: sa240/a240 uns s32900.
Yes, UNS S35315 welds robustly with GTAW/SMAW and ER310/ER320LR fillers; high Si/C (≤0.4%) demands preheat 200°C and PWHT 1100-1150°C (2h) for thick (>10mm) to mend scale, interpass <250°C curbing liquation cracks. ASTM G28 post-weld shows no attack in oxidizing. Gangsteel certs for cyclic, enabling heavy-plate with 15% less preheat than 310. Protocols: sa240/a240 uns s32906.
