304 stainless steel is a versatile stainless steel material, and its anti-rust performance is stronger than that of 200 series stainless steel materials. High temperature resistance is also relatively good, the general use temperature limit is less than 650 ℃. 304 stainless steel has excellent stainless corrosion resistance and good intergranular corrosion resistance. For the oxidizing acid, it is found in the experiment: 304 stainless steel has strong corrosion resistance in nitric acid with a concentration ≤65% below the boiling temperature. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, 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 phenomenon (non-magnetic, use temperature -196℃～800℃). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Has good processing performance and weldability. Plate heat exchangers, bellows, household products (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, etc. 304 stainless steel is food grade stainless steel recognized by the state.
