Material What is the difference between 304 stainless steel and 316 stainless steel

04 stainless steel and 316 stainless steel are two different kinds of steel, their chemical composition, mechanical properties and range of applications are not the same.04 stainless steel and 316 stainless steel are high temperature corrosion resistance, the difference is very obvious:1.304 stainless steel and 316 stainless steel chemical composition is different:304 stainless steel average nickel content is greater than 8.0%, 316 stainless steel average nickel content is greater than 10.0%. Nickel can improve the high temperature durability, mechanical properties and oxidation resistance of metal materials. In addition, 316 stainless steel also contains molybdenum (Mo) which is not found in 304, further enhancing the corrosion resistance of 316 stainless steel.2. 304 stainless steel and 316 stainless steel properties are different:34 stainless steel can not be heat-treated to strengthen, can not be quenched like carbon steel, and no magnetic properties. The acid and alkali resistance and high temperature resistance of 316 stainless steel is stronger than 304 stainless steel, there is basically no 316 stainless steel thermal expansion and contraction phenomenon, which is extremely important for precision parts.34 stainless steel is widely used in civil decoration, machinery, medical, affordable; 36 stainless steel has good resistance to chlorine corrosion, generally used in printing and dyeing, seawater facilities, and other chlorine corrosion resistant parts.
