Stainless Steel Filler Wire




SUPERMIG 307Si is suitable for welding dissimilar steels between unalloyed steels, austenitic stainless steels or heat resisting steels, also used for welding of hardening and tempering steels, such as ballistic steels. The increased silicon content promotes weld pool fluidity to give a smooth deposit appearance.
