304 stainless steel is a universal stainless steel material, and its rust resistance is stronger than that of 200 series stainless steel materials. The high temperature resistance is also relatively good, and the general operating temperature limit is less than 650 °C.
304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. For oxidizing acids, it was found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid with a concentration of ≤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. It has good hot workability such as stamping and bending. Heat treatment hardening phenomenon (non-magnetic, operating temperature -196 ℃ ~ 800 ℃).
Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Has good processability and weldability. Plate heat exchangers, bellows, household products (Class 1 and 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 a nationally recognized food grade stainless steel.
Through the above understanding, you know why the packaging machine chooses 304 stainless steel. Because the packaging machine is used as the equipment for packaging materials, it involves a wide range of applications. Industry, food, agriculture, chemical industry, etc. all need to use packaging machines for material packaging.
