TIG Hardfacing

Tig wire for difficult welded steels and stainless steels against regular steels. Joining and hardsurfacing parts, buffer layers before hardfacing to avoid cracks and welding tool steels, manganese steels etc.

Cr-Mo alloyed steels (1,5% - 0,5%) resistant to high temperature, wear, pressure and shocks. Good resistance to cracking and to the attack of sulphured agents. Guide roller, excavators, screw conveyers, gears, moulds, rolling surfaces, etc.

For surfaces where it is required a fairly good impact strength and a good resistance to shocks; martensitic steel. Excavators, mining industry, cylinder crushers hammers, pneumatic hammers, knives, cutting and cold working tools, crumbling jaws, anvils, catepillars, screws, guide rollers, etc.

Used on Cr-Mo and Ni-Cr-Mo alloyed materials when hardness, resistance to heat on parts subject to friction, compression and good impact strength at high temperature are required. Repairing and/or restoration of cylinders, conveyor and guide rollers, shear blades, forging, punches, percussion hammers, hot and cold working tools of middle hardness.

Cobalt, chrome, high tungsten content. Excellent for abrasion and corrosion resistance. Retains hardness at temperatures exceeding 760ºC. 54HRC

Wear pads, mixer Rotors, pump sleeves

Cobalt, chrome, high tungsten content. Excellent for corrosion resistance and wear. Most flexible of the cobalt alloys due to overall performance. Retains hardness at temperatures exceeding 500ºC. 42HRC

Shear blades, fluid flow valves, extrusion screws, roll bushings, valve bearing surface

Very high chrome, high tungsten and high carbon content. High resistance to corrosion and galling at elevated temperatures. Maintains hardness up to 700ºC. 49HRC

Cobalt, high chrome, molybden content. Excellent corrosion resistance, galling, cavitation and metal to metal wear resistance. Not recommended for severe abrasion. 32HRC

Steam valves, hot shears, chemical and petrochemical valves, cavation repair, forging dies
