HFT 4S
Hardfacing electrode for metal wear
Description & applications
Rutile coated electrode with a martensitic steel deposit containing fine carbides of W, Cr and V. The principal property of the deposit is its resistance to metal/ metal wear up to 550°C. The deposit is only machinable after soft annealing at 750 – 800°C / 4 hours, followed by slow cooling in an oven. In order to obtain a hardness of 50HRC the deposit can be tempered after machining (1100°C/ oil or compressed air). Can be used for reclaiming, a final pass using HB600HT is often recommended. Soft fusion, no projections, self releasing slag.
General applications: Hardfacing of trimming and blanking dies, of shear blades, of cold and hot working dies of punches, hot shearing knives, forging dies…
