TDM-8 Tungsten Carbide Hardfacing Electrodes

TDM-8 tungsten carbide hardfacing electrodes

Description: TDM-8 tungsten carbide hardfacing electrodes Building Materials Industry recommended products I plant the TDM-8 tungsten carbide hardfacing electrodes, mainly for the delivery of brick spiral mixer blades, brick machine mixing blade, auger, to stick, bulldozers push the bucket, digging bucket, grab and wear characteristics, such as the development.

Tungsten carbide and low hydrogen sodium type coating as the main raw material, with the process technology developed by Kobe, Japan, AC and DC welding layer has high hardness, good toughness, high temperature and wear-resistant characteristics, the use of carbon surfacing prime steel, alloy steel, cast iron, cast steel and other surfaces.

Surfacing Metal: high manganese steel welding core, the amount of 57% tungsten, and gold powder 12%, Mexico cobalt chromium and other elements.

Chemical Composition (%):
C Cr W Mo B
0.05 9.8 5717 4.2

Reference current: φ3.2 90-120A φ4.0 160-190A φ5.0 190-220A

:( Surfacing layer hardness after welding, air-cooled) HRC≥75

Note: 1, before welding debris shall clean the surface of the base metal. 2, should use a smaller current to prevent anti-crack three arcs, such as welding thicker layer can be repeatedly surfacing
