Armorweld 307 is designed to produce moderate strength-crack resistant weld deposits in armor plate and between dissimilar steels such as 14% manganese steel to carbon steel forgings or castings.
THE PERFECT ELECTRODE TO USE ON “DIFFICULT TO WELD STEELS.” Excellent for joining wear resistant steel plates of high tensile strength, for welding stainless steel to carbon steel and for building up rails. Commonly used in mining and dredging equipment as well as within steel manufacturing facilities. Armorweld 307 deposits offer excellent toughness and corrosion resistance. Weld deposits remain crack-resistant without any preheat or postheat treatment. Heat resistance up to 1460°F. Impact properties remain strong down to -150°F. Weld deposits are non-magnetic and they are machinable in the “as-welded” condition, however Armorweld 307 deposits do work-harden (up to RC52) when put into service. Beautiful welds with AC current!
