304 stainless steel coil is a highly versatile and widely used stainless steel product known for its excellent corrosion resistance, superior mechanical properties, and affordability. Composed primarily of iron, chromium (18–20%), and nickel (8–10.5%), SS 304 coil delivers outstanding oxidation resistance and performs reliably in a wide range of environments, including mildly acidic or alkaline conditions.
As one of the most commonly used austenitic stainless steel grades, 304 stainless steel coil is favored across industries such as food processing, chemical equipment, construction, medical devices, and transportation. Its smooth surface finish, high ductility, and superior toughness make it suitable for both hot rolling and cold rolling processes, enabling the production of coils that meet diverse application requirements.
Whether you need cold rolled 304 stainless steel coil for precision fabrication or hot rolled 304 coil for structural applications, this alloy provides a reliable and cost-effective solution.
