316 contains many similar chemical and mechanical properties as 304 stainless steel. To the naked eye,the two metals

look the same. However, the chemical composition of 316, which is made up of 16% chromium,10% nickel, and 2%

molybdenum, is the main difference between 304 and 316 stainless steel.
