#347H stainless steel pipe | 347H stainless steel seamless pipe , #S34709 SS PLATE
The 347H stainless steel pipe is made of austenitic stainless steel stabilized with Nb element. The 347H stainless steel pipe has good resistance to intergranular corrosion and intergranular stress corrosion of polysulfuric acid. The corrosion resistance of 347H stainless steel seamless pipe in corrosive media such as acid, alkali, and salt is basically the same as that of 321 stainless steel containing Ti.
Cold working can significantly increase the strength of 347H stainless steel seamless pipe, accompanied by a decrease in plastic toughness. Suitable cold deformation degrees can be selected according to usage requirements to obtain satisfactory strength and plastic toughness matching of #347Hstainlesssteelpipe
