To support companies in the quest of reducing maintenance costs, Castolin Eutectic recently launched the DH Wearfacing Alloy Range, providing high performance solutions for hot abrasion / erosion environments.

Dispersion Hardening is the solid state diffusion process in which small, submicron, dispersoid particles of a new phase precipitate in the crystalline matrix to harden the alloy by hindering dislocation movements. The Dispersion Hardening alloys have mesomorphous characteristics which is an intermediate, hybrid state between crystalline and amorphous.
 
“Why consider the maintenance department a department that creates costs and not a department that generates value for the Company? Dispersion Hardening (DH) Range of welding alloys has been developed in accordance with this philosophy and is looking for the best results to generate a “real” benefit in technical, commercial and financial departments, ” said Enrique Matey, manager of the Welding Consumables Business Unit at Castolin Eutectic.
 

EutecTrode 6070 N is a high speed performance electrode with 250% metal recovery for wearfacing components against abrasion and erosion, especially where both fine and coarse grain mineral particles are present. It is especially good when high temperatures are part of the process and is suitable for a wide range of steels including medium carbon steel, low alloy steels and austenitic manganese steels.

 
EnDOtec DO*8336 is a high temperature oxidation resistance to 850°C. It’s main Application is for steel, cement, waste and recycling, transport screws, furnace chutes, exhaust fans, cyclones, conveyors, mixer blades. It is designed for protective coatings with extreme resistance to abrasion, erosion combined with moderate shock on carbon, alloy, stainless and cast steels and for sinter plant ventilator fans, agglomeration fans, screws and heads in the ceramics industry.
 
EnDOtec DO*33 has a better cost/ wear resistance ratio against severe abrasion than conventional chromium castings. The main applications are public works, brickworks, auarries, dredgers, extruder/press screw segments and pug mill augers, sust extractors, hot screens and furnace retorts
 
The TeroMatec 4395 N is an ideal choice for fieldwork or on site applications. It’s main application is that it is specifically developed for outdoor maintenance and repair welding of thick, heavy components where faster weld deposition rates, are required. Sinter crusher bars, furnace chutes, mixer blades, paddles, scrapers
