Cold Rolled 2B 304 steel sheet
Product Description:
304 is a kind of common stainless steel, it is widely used to make for a good comprehensive performance, corrosion resistance and formability of equipment and parts.In order to keep inherent corrosion resistance of stainless steel, steel must contain more than 18% of chromium, more than 8% of the nickel content.
304 stainless steel is according to the United States ASTM standards to produce a brand of stainless steel.304 stainless steel is one of the most widely used chrome - nickel stainless steel , as a wide range of steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties;Punching, bending, such as hot workability is good, no heat treatment hardening phenomenon (using the temperature to 196 ºC ~ 800 ºC).
In the atmospheric corrosion resistance, if is the industrial atmosphere or heavy pollution area, you will need to clean in time to avoid the corrosion.Suitable for use in food processing, storage and transportation.Has a good processing performance and weldability.Plate heat exchanger, corrugated pipe, household goods (1, 2 kinds of tableware, cabinets, indoor pipeline, water heater, boiler, bath), auto parts windshield wiper, muffler, molded products, medical appliances, building materials, chemical, food industry, agriculture, Marine parts, etc.Food grade stainless steel of 304 stainless steel for the world.
