304 has good heat resistance, corrosion resistance, low temperature strength and mechanical properties. It has good hot workability such as stamping and bending, and has no heat treatment effect (non-magnetic, use temperature -96 -800. Household items (1, 2 types of tableware, kitchen cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts, medical utensils, building materials chemistry, food industry, ship parts.


As a low C steel, 304L has similar corrosion resistance to 304 steel under normal conditions, but it has excellent resistance to intergranular corrosion after welding or stress relief; it can be maintained without heat treatment. Good corrosion resistance, use temperature -196 C ~ 800 C. It is used in field open-air machines for chemical, coal, and petroleum industries with high resistance to intergranular corrosion, heat-resistant parts for building materials, and parts with difficult heat treatment.

316 Because of the addition of Mo, it has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength, and can be used under severe conditions; it has excellent work hardening property (non-magnetic). Equipment exchange for pulp and paper, dyeing equipment, film processing equipment, pipelines, and materials for outdoor construction in coastal areas.

321 Ti element is added to 304 steel to prevent grain boundary corrosion; suitable for use at temperatures between 430 C and 900 C, such as Aircraft, exhaust pipe, boiler drum
