Which Of Stainless Steel 304 And 316 Is Easy To Rust?

Both 304 and 316 stainless steel are commonly used stainless steel materials, and they are slightly different in terms of rust resistance.

304 stainless steel is a general-purpose stainless steel material, mainly used in the manufacture of kitchen utensils, decorations, building materials, etc. Its main component is chromium, accounting for about 18-20%, nickel accounting for 8-10.5%, and the rest are iron and other elements. 304 stainless steel has good antirust performance and can resist corrosion in common atmosphere, water, acidic and alkaline environments. However, in a chloride environment, the rust resistance of 304 stainless steel is relatively poor, and pitting and intergranular corrosion are prone to occur.
316 stainless steel is a stainless steel material with high strength and good corrosion resistance. It is mainly used in the manufacture of chemical equipment, marine equipment, medical equipment, seawater treatment equipment, etc. Its main components include chromium, nickel and molybdenum, wherein the chromium content is about 16-18%, the nickel content is about 10-14%, and the molybdenum content is about 2-3%. 316 stainless steel has excellent anti-rust performance, and has good anti-oxidation, corrosion resistance and high temperature resistance. It is resistant to chlorides and other strong acidic and alkaline environments, so it is widely used in marine environments and chemical environments.

Therefore, in general, the rust resistance of 316 stainless steel is better than that of 304 stainless steel, especially in the chloride environment, the corrosion resistance of 316 stainless steel is stronger.
