Heat Resistant Stainless Steel Strip 310S 321 Grades 0.2-4mm ASTM A167

Heat-Resistant Stainless Steel Strip, 310S/321 Grades, 0.2-4mm, ASTM A167

Heat-Resistant Stainless Steel Strips (Grades 310S/321) are designed for extreme-temperature applications, offering exceptional oxidation resistance and mechanical stability up to 1,100°C. Compliant with ASTM A167 standards, these strips are manufactured in thicknesses ranging from 0.2mm to 4mm, ensuring versatility for both industrial and specialized uses. Grade 310S, with high chromium and nickel content, excels in continuous high-heat environments, while Grade 321 incorporates titanium stabilization to prevent carbide precipitation during welding. Their superior thermal fatigue resistance and corrosion durability make them indispensable for furnaces, exhaust systems, and chemical processing equipment.
