1. 304 stainless steel.
It is one of the most widely used austenitic stainless steels, which is suitable for manufacturing deep drawing forming parts and acid conveying pipes, containers, structural parts, various instrument bodies, etc. It can also manufacture non-magnetic and cryogenic equipment and parts.
2. 304L stainless steel.
In order to solve the serious intergranular corrosion tendency of 304 stainless steel due to the precipitation of Cr23C6, the sensitized ultra-low carbon austenitic stainless steel is significantly better than 304 stainless steel.
In addition to the slightly lower strength, other performance as 321 stainless steel, mainly used for welding and can not be solid solution treatment of corrosion resistance equipment and components, can be used to manufacture various instrument bodies.
3. 316 stainless steel.
Molybdenum is added on the basis of 10Cr18Ni12 steel, so that the steel has good resistance to reducing medium and resistance to point corrosion.
In seawater and other media, the corrosion resistance is better than 304 stainless steel, mainly used for pitting corrosion resistance materials.
4. 316L stainless steel.
Ultra-low carbon steel, with good resistance to sensitized intercrystalline corrosion, is suitable for manufacturing thick section size welding parts and equipment, such as petrochemical equipment corrosion resistant materials.
