Castolin Eutectic recently launched the Dispersion Hardening (DH) wearfacing alloy range to support companies seeking to reduce maintenance costs. Castolin Eutectic’s DH wearfacing alloy range provides high performance solutions for hot abrasion/ erosion environments.
Dispersion Hardening is a 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 belong to an intermediate, hybrid state between Crystalline and Amorphous.
According to Enrique Matey, Manager of the Welding Consumables Business Unit at Castolin Eutectic, the DH range of welding alloys has been developed in accordance with the philosophy that the maintenance department is not a cost centre but a department that generates value for the company.
EutecTrode 6070 N - High speed performance electrode with 250% metal recovery
Used for wearfacing components against abrasion and erosion, especially where both fine and coarse grain mineral particles are present, it performs especially well in high temperature processes. The electrode is suitable for a wide range of steels including medium carbon steel, low alloy steels and austenitic manganese steels.
EnDOtec DO*8336 - High temperature oxidation resistance to 850°C
Used in steel, cement, waste and recycling applications including transport screws, furnace chutes, exhaust fans, cyclones, conveyors and mixer blades, the alloy is designed for protective coatings with extreme resistance to abrasion and erosion combined with moderate shock on carbon, alloy, stainless and cast steels. It is also suitable for sinter plant ventilator fans, agglomeration fans, screws and heads in the ceramics industry.
EnDOtec DO*33 offers better cost/ wear resistance ratio against severe abrasion than conventional chromium castings, and finds application in public works, brickworks, quarries, dredgers, extruder/press screw segments, pug mill augers, and dust extractors.
TeroMatec 4395 N - Ideal choice for fieldwork or on site applications
Specifically developed for outdoor maintenance and repair welding of thick, heavy components where faster weld deposition rates are required, the alloy is recommended for sinter crusher bars, furnace chutes, mixer blades, paddles and scrapers.
