Exaton 309/309L
309/309L is suitable for joining stainless Cr-Ni steels of the 309 type, Cr-steels and dissimilar steels e.g. austenitic stainless steel to carbon or low-alloyed steels for service up to 320°C (610°F). It is used for MIG/MAG welding. Widely used as barrier layer between carbon/low alloy steel and different stainless grades in cladding operations.
