SA312 TP317L Best quality 317l Stainless Steel Tube and SS UNS
S31703 Seamless Pipe
Stainless steel 317l belongs to a low carbon austenitic grade. It
is produced via the extrusion process where heated steel billets
are passed through the metal creating a hollow opening. The
Stainless Steel 317L Pipe is designed with a chemical composition
consisting of iron, chromium, nickel, molybdenum, manganese,
silicon, phosphorous, carbon, and sulfur. The content embedded in
them allows these modules to possess enhanced corrosion and
oxidation resistance properties across stress-induced environments.
Stainless Steel Grade 317L Pipe works well in aqueous conditions
due to the content of molybdenum within them. The lower carbon
content also allows them to be resistant to sensitization and gives
them higher creep-rupture properties. The 317l stainless steel
tubing is non-magnetic in the annealed condition. They can be
readily welded in place following standard procedure. The grade can
be dual certified by the addition of a strengthening agent like
nitrogen in its composition. The tubes cannot be heat treated but
are usually cold worked to harden them in the system.
Applications:
317L stainless steel Pipes are suitable for vertical organizations
for boiler units, construction industry, heat exchangers units,
chemical & Fertilizer production, surgical instruments, power
generation plants, Chillers & Cooling system, engineering oil and
gas and shipbuilding, for onshore & offshore industries,
exploration, Pulp & Paper Defense, Industry, LNG, fasteners,
Desalination, Aerospace, Automobile, Cross Country Pipe Line for
sugar industry, Gas & Water, Nuclear and Solar Power Plants,
Thermal, Sewage & Waterwell Industry Atomic Energy, hydrocarbon
process.
