Overview
ASTM A403 is a balanced, austenitic, chromium steel containing columbium which takes into consideration the end of carbide precipitation, and thus intergranular corrosion. ASTM A403 is balanced out by the increases of chromium and tantalum and offers higher creep and stress rupture properties than A304 and A304L, which may also be utilized for exposures where sensitization and intergranular corrosion are of concern.The expansion of columbium likewise permits ASTM A403 to have outstanding corrosion resistance, better than that of A321. ASTM A403H is the higher carbon composition form of ASTM A403 and display enhanced high temperature and creep properties.
SS347 is a balanced, austenitic, chromium steel containing columbium which takes into consideration the end of carbide precipitation, and thus intergranular corrosion. SS347 is balanced out by the increases of chromium and tantalum and offers higher creep and stress rupture properties than SS 304 and 304L, which may also be utilized for exposures where sensitization and intergranular corrosion are of concern.The expansion of columbium likewise permits SS347 to have outstanding corrosion resistance, better than that of SS 321. SS347H is the higher carbon composition form of SS 347and display enhanced high temperature and creep properties.
ASTM A403 WP347 stainless steel butt-weld pipe fittings that are weldable onto the pipes they need to fit on. There are different types, forms and shapes of fittings available. The functions include changing the direction of fluid flow, reducing the diameter of the pipeline, joining two fluid flow lines together and splitting a line into two. The A403 WP347 Elbow functions to change the direction of fluid flow but is more abrupt than the bend. ASTM A403 gr WP347 fittings vary in shape and function such as the union, adapter, double-tapped bushing, coupling and valves. A403 WP347 material is austenitic stainless steel specialized for pressure pipes.
