Stainless Steel 304 stainless steel is one of the most versatile and commonly used stainless steels on the market, and is the most standard used alloy of this type. Grade 304 is essentially an austenitic chromium alloy which is also called an “18/8” stainless because the make-up of the steel is 8% nickel and 18% chromium.The chromium content promotes the significant resistance of the material to the effects of oxidation and corrosion.
Stainless Steel 304 has deep drawing and excellent welding characteristics – it is easy to clean, easy to fabricate, and aesthetically pleasing to the eye.
