Is 304 or 316 stainless better?

Date:May 18, 2019

304 and 316 stainless steel's  physical properties are similar. The mechanical properties of 304 and 316 stainless steel also are similar. The tensile strength, yield strength, elongation and section shrinkage are the same, and the physical properties are the same. However, the corrosion resistance is different. The corrosion resistance of 304 and 316 stainless steel are very good. Meanwhile,  316 stainless steel has more applications in some coastal cities and other areas where the material corrosion requirements are high, the use of 316 stainless steel in the inland areas will have the more application fieles, and the price of 316 stainless steel is higher than that of 316 stainless steel. 304 stainless steel is a lot higher. 

304 stainless steel

Both 304 and 316 are ordinary low carbon stainless steels and are typically 18-8 chrome nickel stainless steel. The composition of the two materials is different. The content of Ni and Cr is different. The oxidation resistance of 316 stainless steel is better than that of 304 stainless steel. Because 316 stainless steel contains Mo (molybdenum), the resistance to chloride pitting in marine and chemical industry environment is better than 304. stainless steel.

316 stainless steel

Comprehensive comparison, 316 material is better than 304, 304 price is also lower than 316, under normal working conditions, 304 material can be used.
