309S stainless steel plate is a high-alloy stainless steel material that belongs to the austenitic stainless steel series. It is mainly composed of elements such as chromium (Cr), nickel (Ni), molybdenum (Mo) and a small amount of titanium (Ti).
317L stainless steel has stronger resistance to chemical corrosion than conventional chromium-nickel austenitic stainless steel such as 304 alloy. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance.
347 stainless steel is an austenitic stainless steel stabilized by niobium. Niobium is added to improve intergranular corrosion resistance. Its corrosion resistance in corrosive media such as acids, alkalis, and salts is the same as that of 321. It has good welding performance and can be used as resistant materials and heat-resistant materials. Steel is used. Parts under corrosion conditions of 400~900 degrees, high temperature welding structural parts.
