S32205 S31803 Duplex Stainless Seamless Steel Pipe
Product Spotlights
Stainless steel coil is a steel product formed by winding hot-rolled or cold-rolled stainless steel sheets into a coil shape, which facilitates transportation and subsequent processing. It offers excellent corrosion resistance, workability, and surface quality, making it an ideal substrate for manufacturing stainless steel tubes, stamped parts, containers, and decorative materials. Common foreign standards include ASTM A240 (USA), EN 10088-2 (Europe), JIS G4304/G4305 (Japan), and BS 1449 (UK), with typical grades such as 304, 316L, 430 (ASTM), 1.4301, 1.4404 (EN), SUS304, and SUS316L (JIS). To find standard comparison tables, search “stainless steel coil ASTM vs EN standard”; for corrosion resistance of different grades, use “304 vs 316L stainless steel coil corrosion resistance”; for common width ranges, search “stainless steel coil standard width chart”; to compare hot-rolled vs cold-rolled coils, use “hot rolled vs cold rolled stainless steel coil”.
Stainless steel coils in China mainly follow GB/T 4237 (hot-rolled) and GB/T 3280 (cold-rolled) standards. Common grades include 06Cr19Ni10 (equivalent to 304), 022Cr17Ni12Mo2 (equivalent to 316L), 06Cr13 (equivalent to 410), and 10Cr17 (equivalent to 430). Cold-rolled coils typically have thicknesses from 0.3 mm to 3.0 mm, while hot-rolled coils range from 3.0 mm to 14.0 mm; common widths are 1000 mm, 1219 mm, 1500 mm, etc. To cross-reference Chinese grades with foreign standards, search “06Cr19Ni10 equivalent in ASTM A240”; for domestic coil size specifications, use “GB/T 3280 stainless steel coil size list”; for mechanical properties of Chinese grades, search “Chinese stainless steel coil tensile strength chart”; for a sample Chinese mill certificate, use “China stainless steel coil mill certificate example”.
Stainless steel coils are widely used in architectural decoration (exterior wall panels, elevator door frames, curtain wall linings), kitchenware manufacturing (sinks, range hoods, countertops), chemical containers, food processing equipment, pharmaceutical machinery, electronic product housings, and automotive components. In coastal or highly corrosive environments, 316L (1.4404) coil is preferred; in general atmospheric conditions, 304 coil is sufficient. For coil selection for building facades, search “stainless steel coil for building facade cladding”; for surface requirements of food-grade coils, use “food grade stainless steel coil surface finish”; for hardness requirements for stamping applications, search “stainless steel coil for deep drawing hardness”; for kitchenware manufacturing examples, use “stainless steel coil for kitchen sink fabrication”.
In international sourcing, key factors to consider include stainless steel grade and standard, thickness and width tolerances, surface finish (2B, BA, NO.1, HL, etc.), coil weight, and inner diameter (typically 508 mm or 610 mm). It is also important to confirm the delivery condition (e.g., solution annealed, pickled, skin-passed) and whether edge treatment (slit edge or mill edge) is required. For thickness tolerance standards, search “stainless steel coil thickness tolerance ASTM A480”; to compare surface finishes for different applications, use “2B vs BA stainless steel coil finish”; for international spot prices, use “stainless steel coil price per ton 2025 USA”; for a global supplier directory, use “stainless steel coil suppliers Europe directory”.
