Stainless Steel Pipe Tube A312/ A312M TP317 S31700 Used in furnace material
Introduction to products:
Alloy 317L (UNS S31703) is a low carbon corrosion resistant austenitic chromium-nickel-molybdenum stainless steel. The high levels of these elements ensure that the alloy has superior chloride pitting and general corrosion resistance to traditional grades 304/304L and 316/316l. In strong corrosive environments with sulfur-containing media, chlorides and other halides, the alloy offers corrosion resistance relative to 316L.
The low carbon content of 317l alloy makes it free of intergranular corrosion caused by chromium carbide precipitation during welding, making it able to be used in the welded state. With the addition of nitrogen as a fortifying agent, the alloy can obtain dual certification for Alloy 317 (UNSS31700).
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.
