DIN 8555

G21 UM 55 CG

Flexible rod for hard surfacing by oxy-gas welding. Consist of a small diameter pure nickel core wire thickly coated tungsten carbides in a Ni-Cr-B-Si matrix. The weld metal is a heterogeneous metal composed of tungsten carbides (W2C,WC) distributed in a hard and tough matrix. Shows extremely high abrasion resistance. It has got a quiet melting and good wetting. Especially used for hard surfacing of mixers, crushing mills, die blades and heads, sand foundary equipment, drilling tricones.

WSG 20 GO 55 CTZ

Co-Cr-W alloy GTA (TIG) welding rod for hardfacing applications. Weld metal has got high resistance to metal-to-metal wear, corrosion and high temperatures from 500°C to 900°C. Resistant to low and medium level of mechanical and thermal shocks, due to its high hardness. Widely used for hard surfacing of wire guides, rolling mill guides, extrusion dies and screws, valve seats, mechanical parts of steam turbines, cement screws, continuous casting dies and parts, pump tubing and shafts, mixes blades, wood saws.
