These factors include but are not limited to the type of steel type of weld loading on the welded joint applicable codes level of preheat level of restraint position of welding condition of the steel and service conditions. This is because the additional alloying elements in Type 308 will better stabilize the weld area.
Also we must realize that selection of a filler alloy that is not recommended for our specific application may result in inadequate service performance and possibly premature failure of the welded joint.
Weldment design and weld orientation The ability to flow into gaps is closely related to viscosity. Use Type 308 filler to weld Type 304 stainless.
