Mac Trode E630
AWS E307-16
Descriptions & Applications:
Tough high strength, fully austenitic electrode, designed to resist heat and impact. Fully machinable. Weld deposit will work harden under impact and retain properties at high temperatures. For joining or overlaying mild and alloy steels, spring steels, heat resisting steels, ideal for the repair of drop forging dies. Suitable for use as a buffer layer prior to hard surfacing of manganese steel, and may be used for welding manganese steel rails or similar applications involving friction, impact or corrosion.
