DAIKOWT 307

These consumables are versatile for mixed welding applications, including mild, stainless, hardenable, and armor steels, with or without preheat. Their high manganese content provides tolerance to dilution, resisting hot cracking. This makes them a viable alternative to high nickel weld metal in joints between cast iron and stainless steels. Post-weld heat-treated weldments maintain ductility with satisfactory toughness down to -50°C. They offer reasonable scaling resistance up to 850°C. These consumables can function as buffer layers for welding or reclaiming 13% Mn steel in rock crushing plants and earth-moving equipment. They also work well as buffer layers on cast iron before hard surfacing. Additionally, they serve as surfacing consumables, work-hardening from 200 to 400 HV, suitable for repairing alloy rails, crossing parts, frogs, etc., without requiring preheat. However, note that the work-hardening rate is lower than 13% Mn steel, and overlays of more than one layer may collapse under heavy rolling loads.
