Stainless steel coils are the basic raw material for both cold-rolled and hot-rolled stainless steel processes. They serve as the precursor base material for various stainless steel sheets, pipes, and stamped parts, encompassing two main categories: cold-rolled and hot-rolled stainless steel coils. The full range covers materials such as SUS200 chromium-manganese-nickel, SUS300 austenitic, SUS400 ferritic/martensitic, duplex steel, and high-temperature resistant special steel. Mainstream grades include 201, 304, 304L, 316, 316L, 321, 310S, 430, 1Cr13, 3Cr13, and 2205.

201 stainless steel coil is a nickel-saving stainless steel with a high manganese content and a low nickel content. It has good acid and alkali resistance, high density, no bubbles or pinholes after polishing, and is easy to process and form. 201 stainless steel coil is mainly used in architectural decoration, industrial pipe manufacturing and shallow drawing products, but due to its relatively weak corrosion resistance, it is not suitable for humid, high salinity or highly corrosive environments.

304 stainless steel coil is a high-quality iron-nickel-chromium alloy coil with excellent corrosion resistance and good plasticity. It has a smooth surface, is easy to clean and maintain, and can resist corrosion from a variety of chemicals. 304 stainless steel coil is widely used in food processing, petrochemicals, shipbuilding, household appliances and other fields. It is one of the most common stainless steel coils on the market, and its strength and toughness can meet a variety of usage requirements.

316 stainless steel coil is a high-quality stainless steel material containing elements such as chromium, nickel and molybdenum, with good corrosion resistance and high temperature resistance. It has a wide range of thicknesses and can be customized according to customer needs. It has excellent surface quality and good brightness. 316 stainless steel coil is widely used in many fields such as automobiles, construction, kitchenware, chemical processing, etc., and is highly favored for its excellent performance.

321stainless steel coil is a martensitic stainless steel with high chromium content, good corrosion resistance and high strength. Its moderate carbon content makes 410 stainless steel coil excellent in hardness and wear resistance. This material is widely used in knives, automotive parts, architectural decoration and other fields, suitable for parts that need to withstand high loads and wear. 410 stainless steel coil is easy to process and weld, and can be provided in different specifications and sizes according to customer needs.

420 stainless steel coil is a ferritic stainless steel with good corrosion resistance, oxidation resistance and shape retention. It has excellent deep drawing performance and is suitable for cold working process. 430 stainless steel coil is widely used in home appliances, kitchen utensils, architectural decoration and other fields because it is easy to process, form and cost-effective. Although its welding performance and temperature resistance are relatively average, it performs well in non-harsh environments and is one of the representatives of economical stainless steel materials.

310S stainless steel coil is an austenitic chromium-nickel stainless steel, containing a high proportion of chromium and nickel, with good oxidation resistance, corrosion resistance and high temperature resistance. Its working temperature can reach 1200℃, and the continuous use temperature can reach 1150℃, which is suitable for high temperature environments in the petroleum, chemical, electric power and other industries. 310S stainless steel coil is easy to process and weld, and is widely used in the manufacture of high temperature components such as furnace components and automobile purification devices.

304L stainless steel coil is an ultra-low carbon version of 304 stainless steel. It is an austenitic stainless steel with excellent corrosion resistance, heat resistance and good mechanical properties. Its chemical composition has high chromium and nickel content and extremely low carbon content, which enhances its ability to resist intergranular corrosion. 304L stainless steel coil is widely used in chemical, food, medical, construction and other fields. Due to its good processing performance and welding performance, it can meet the manufacturing needs of various complex shape parts.

1Cr17Ni2 (SUS431) Stainless Steel Coil is a high‑chromium nickel martensitic stainless steel with high strength, good toughness and moderate corrosion resistance. Supplied in hot rolled or cold rolled, solution annealed, pickled and leveled condition, the coil features flat shape, uniform thickness, clean surface and stable microstructure. I
