Durmat-A 3505 x 700mm 0.25-0.7mm Duroweld

Tungsten hardfacing rod. DURMAT A consists of a special pre-alloyed tube filled with coarsely grained Fused Tungsten Carbide (FTC) for oxyacetylene welding. The FTC has an exceptionally high hardness of over 2360 HV giving outstanding wear protection to hard-faced areas. For special hard-facing on machine parts of unalloyed, low alloyed or cast steel with carbon content up to 0.45%. Higher carbon content could lead to cracking. Depending on size and composition of the area to be hard-faced, the proper rod diameter and grain size should be chosen. If the area will encounter heavy abrasion a small grain size is recommended. If cutting action is desired a larger grain size is preferable.
