A358 TP309 Stainless Steel Tube
GNEE's A358 TP309 stainless steel pipes are produced using various manufacturing processes, including hot or cold working, and then the pipes are subjected to various tests to ensure that specified requirements are met.
A358 TP309 austenitic stainless steel pipe is specially developed and applied for high temperature corrosion repair. This A358 TP309 stainless steel boiler tube can resist oxidation up to 1038°C under non-cycling conditions. Due to the high chromium and low nickel content of the A358 TP309 high temperature tube, the A358 TP309 corrosion-resistant stainless steel tube can withstand sulfur-containing atmospheres up to 1000°C. use.
A358 TP309 high temperature stainless steel pipe is widely used in the manufacture of boilers, pressure vessels and heat exchangers in fertilizer plants, chemical plants, refineries and power plants due to its excellent heat resistance.
