The Difference In Material Performance(SS304 And 316)

- Jun 17, 2020-

304 (0Cr18Ni9) stainless steel is austenitic stainless steel, which cannot be strengthened by heat treatment, cannot be quenched like carbon steel, and has no magnetic properties. All kinds of mechanical properties of 304 are excellent, with considerable corrosion resistance and high temperature resistance. It is the most widely used as stainless heat-resistant steel.


316 (0Cr17Ni12Mo2) stainless steel is the second most widely used steel type after 304. Its main characteristics are acid and alkali resistance and high temperature resistance. It is mainly used in the food industry and surgical equipment, and 316 stainless steel Another significant feature is that there is basically no phenomenon of thermal expansion and contraction, which is extremely important for precision parts.
