Stainless Steel Pipe Tube A312/ A312M TP317 S31700 Used in furnace material
Introduction to products:
317L stainless steel has stronger chemical resistance 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. It is a low carbon grade or L grade, which has resistance to sensitization during welding and heat treatment.
APPLICATIONS :
Compared with 316L, 317L steel has good seawater resistance and SCC resistance, which is used in Chemical ships, chemical products Reactor and other chemical equipment requiring high corrosion resistance.
