SUPRANOX 308L is a rutile coated MMA electrode for welding similar austenitic stainless Cr-Ni steels, also suitable for ferritic stainless Cr-steels. Metal transfer in fine droplets and nearly spatter free, the slag is generally self releasing from finely-rippled concave fillet welds with an excellent bead surface appearance. Good striking and restriking. Under wet corrosive conditions, suitable for operating temperatures <350°C, non-scaling <800°C.
