ASTM A312 TP317 SS Welded Pipe

GNEE is a professional manufacturer and exporter of A312 stainless steel pipes.
GNEE supplies ASTM A312 stainless steel 317 electric resistance welded pipes with outer diameters ranging from ½ inch to 24 inches. The chemical composition includes 18% chromium, 12% nickel and 3.5% molybdenum, which has better pitting resistance than 316 steel pipes.
In addition, A312 TP317 stainless welded steel pipes also have high ductility, stress corrosion resistance, and stronger chemical corrosion resistance compared to traditional chromium-nickel austenitic stainless steels such as 304 alloy. ‌It can be customized to meet different application needs through a variety of processing processes such as flattening, drawing, welding, stamping, laser cutting, forging, surface treatment, etc.
