Corrosion Resistance Of 304 And 316 Stainless Steels
Oct 26, 2018

The corrosion resistance of 316 is higher because it contains Mo, which has excellent corrosion resistance, especially pitting corrosion resistance. Corrosion resistance is superior to 304 stainless steel, and it has good corrosion resistance in the process of pulp and paper production. And 316L stainless steel is also resistant to ocean and corrosive industrial atmosphere erosion. 304 stainless steel is a kind of universal stainless steel material. Resistance to high temperature also is better, generally use temperature limit is less than 650 ℃. 304 stainless steel has excellent rust resistance and intercrystalline corrosion resistance. 316 stainless steel, 18cr-12ni-2.5 Mo is particularly good in corrosion resistance, atmospheric corrosion resistance and high temperature strength due to the addition of Mo. The actual application environmental conditions in engineering are very complex. The combination of different medium, medium temperature, medium pressure and other operating conditions constitutes countless material selection conditions. In terms of common material selection conditions, we want to give the material selection knot here one by one. The corrosion resistance of stainless steel is mainly determined by the Ni and Cr in the material composition. The Ni Cr content of 316 is higher than 304, so the corrosion resistance is better.
