GNEE is a manufacturer and exporter specializing in the production of A312 stainless steel pipes. The outer diameter of stainless steel 317 electric resistance welded pipes ranges from ½ inch to 24 inches. The chemical composition of 317 stainless steel includes 18% chromium, 12% nickel and 3.5% molybdenum, and its pitting resistance is better than that of 316 steel pipes.
In addition, A312 TP317 steel pipes also have high ductility, stress corrosion resistance, compressive strength and high temperature resistance. Compared with conventional chromium-nickel austenitic stainless steel such as 304 alloy, 317 alloy pipes show stronger resistance to chemical corrosion.
It also has good processability and can be customized through a variety of processing processes such as flattening, stretching, welding, stamping, laser cutting, forging, surface treatment, etc. to meet different application requirements.
