Not welding rod, alloy heads it should, alloy heads! Welding rod, then, is to use the welding electrode wear in the blade portion surfacing increased hardness and abrasion. D036 red carrier Edge Surfacing Electrode Description: punch die edge surfacing electrode, AC-DC dual-use, good welding process, surfacing layer and hardness stability, without preheating before welding, post-weld heat treatment. Uses: for welding manufacturing and repair die (surfacing on steel substrate to form a cutting edge), can also be used to repair and require high wear resistance mechanical parts. The chemical composition of the deposited metal /% C 0.5-0.7 Si 0.6-0.8 Mn 0.6-0.9 Cr 5-6 Mo 1.5-2 V ≈ 0.5 Air cooling after surfacing hardness HRC: ≥ 55 (welding)
