There are many types of stainless steel material, so the choose and buy when stainless steel chair how to distinguish? 304 is a kind of common stainless steel, widely used to produce good comprehensive performance ( Corrosion resistance and formability) Equipment and parts. 301 stainless steel at the time of deformation presents obvious work hardening phenomenon, relatively high strength is used for various occasions. 302 stainless steel is essentially higher variations of 304 stainless steel, the carbon content by cold rolling it can get higher strength. 302 b is a kind of high silicon content of stainless steel, it has a higher resistance to high temperature oxidation performance. Se is 303 and 303 respectively containing sulfur and selenium free cutting stainless steel, used for main requirements free cutting and table and finish high. 304 l is a variation of carbon content is low of 304 stainless steel, welding is applied to the occasion. Low carbon content is made in the heat affected zone near the weld in the precipitation of carbide to a minimum, and may result in precipitation of carbide stainless steel intergranular corrosion in some environments ( Welding erosion) 。
