Meltolit 250 XT
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.
Meltolit 600 XT
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
