304 stainless steel is a versatile stainless steel material. High temperature resistance is also good, the general use temperature limit is less than 650 °C. 304 stainless steel has excellent stainless corrosion resistance and good resistance to intergranular corrosion. 316 stainless steel, 18C
-12Ni-2.5Mo is particularly good in corrosion resistance, atmospheric corrosion resistance and high temperature strength due to the addition of Mo. It can be used under severe conditions; it has excellent work hardening property (non-magnetic). Both 304 and 316 are austenitic stainless steels, with the difference being that 316 adds 2% more molybdenum. Such 316's corrosion resistance, especially the resistance to chlorine corrosion is better than 304. The price is about 20% more expensive.
