Use & Application
These consumables are designed for welding 316/316H austenitic stainless steels operating at high temperatures (500-800°C) under long term creep conditions. The consumables can also be used for welding 321/321H and 347/347H grades in high temperature structural service. This is particularly important in thick highly restrained weldments, since the possibility of premature service failure by intergranular HAZ cracking is reduced by using more ductile weld metal rather than 347H. Used for welding **steam piping, superheater headers, furnace parts, some gas and steam engine turbine components**, in the petro-chemical industry, in fossil and nuclear fueled power stations. Preheat not required, maximum interpass temperature 250°C. PWHT not required.
