Hard Surfacing Wire

MAXFIL 40H

Maxfil-40H is a basic type low alloy gas shielded wire designed for air hardening type hard surfacing deposit. It has good welder’s appeal & easy slag detachability. Though little hard but the weld is machinable. The wire deposits a crack-free, martensitic weld metal suitable for heavy impact and moderate abrasion resistant applications.

Maxfil-40H wire is suitable for weld-surfacing & reclamation of agricultural equipments, track rollers, links, shafts, pulleys, idle rollers, conveyor parts, axles, shear blades, etc where the applications call for a slight higher order of hardness (40-48 HRC).
