Classification: Stainless steel coils are mainly divided into cold-rolled stainless steel coils and hot-rolled stainless steel coils. Based on metallographic structure, they can also be classified into austenitic, ferritic, martensitic, and duplex types.
Common Grades and Characteristics:
- Austenitic Stainless Steel Coils: Such as 304, 316, 316L, etc., possessing good corrosion resistance and toughness. 304 stainless steel coil (grade 06Cr19Ni10) is widely used in food equipment and chemical industries; 316 stainless steel coil, due to the addition of molybdenum, has superior corrosion resistance and is suitable for chemical containers and medical devices; 316L, as a low-carbon version, has better resistance to intergranular corrosion.
- Other Types: Ferritic stainless steel coils are resistant to high temperatures but have poor toughness; martensitic stainless steel has high strength but weak corrosion resistance; precipitation hardening stainless steel achieves high hardness through heat treatment. – Economy Grades: Such as 201 stainless steel coils, with low nickel content and lower cost, but weaker corrosion resistance, mainly used in dry environments such as building decoration and kitchenware.
Main Applications: Stainless steel coils are used in multiple industries:
- Industrial Sector: Chemical equipment, oil pipelines, machinery manufacturing (such as bearings and gears), medical devices, etc.
- Construction and Decoration: Building structures, bridges, decorative pipes, and household appliance parts.
- Special Environments: 316 series is suitable for marine engineering and highly corrosive environments; cold-rolled steel strips for deep drawing are used for complex drawn parts.
Different grades of stainless steel coils can be selected according to specific needs. For example, 304 is suitable for general corrosion-resistant applications, while the 316 series is more suitable for harsh environments.
