304: S30400
As a steel with a wide range of uses, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability such as stamping and bending, and no heat treatment hardening (non-magnetic, use temperature -196 ℃ ～ 800 ℃). Household items (category 1, 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship parts.
304L: S30403
As a low-C 304 steel, under normal conditions, its corrosion resistance is just similar to 304, but after welding or after stress relief, it has excellent resistance to grain boundary corrosion; it can also be maintained without heat treatment. Good corrosion resistance, use temperature -196 ℃ ～ 800 ℃.
It is applied to the outdoor open-air machinery in the chemical, coal and petroleum industries with high requirements for anti-grain boundary corrosion.
