Shield-Bright 309L X-tra was developed to maximize performance in the flat and horizontal positions when joining stainless to mild or carbon steel.
Shield-Bright 309L X-tra was developed for the welding of stainless steels to carbon or low alloy steels and for the first layer cladding of carbon and low alloy steels. Shield-Bright 309L X-tra was developed for welding in the flat position and for horizontal-vertical fillet welds with flat to concave beads with excellent slag removal.
For joining thick sections, it is preferred the non-stainless steel be buttered with a layer of Shield-Bright 309L X-tra and the joint completed with Shield-Bright 316L X-tra or 308L X-tra. The service temperature should not exceed approximately 750ºF (399ºC).
