Properties &Typical Applications

304,Good corrosion resistance, heat resistance, good ductility and weldability, low-temperature strength, and mechanical properties. Stamping, bending and other good thermal processing, no heat treatment hardening phenomenon.

Used in the food industry such as wine storage, laundry and kitchen products, and household items (class 1 and 2 tableware, kitchen cabinets, indoor plumbing, water heater, boiler, bathtub), construction, low temperature, and high-temperature applications.
