New Materials development

Providing complete solutions for boiler maintenance and performance improvement is our goal. Thanks to our R&D department and the long experience in maintaining boilers, we have developed special products providing unbeatable wear and corrosion resistance: our NanoAlloys® as well as our range of unique powders and wires developed for boiler coating.

NanoAlloys®: Castolin Eutectic has a powerful weapon in the wire alloys for its war on “High Load High Wear” by using a new approach. The world’s first NanoAlloy™ formulation was developed to provide outstanding abrasion and erosion resistance.
This was achieved by using a lower cost ferrous alloy with bulk hardness values reaching 71HRC!

Industry proven Spray and Fuse alloys: Castolin Eutectic was amongst one of the first companies to recognise and offer nickelbased self fluxing alloys as a wear and corrosion resistant coating for boiler tubes in the 1980s and have developed a considerable reputation and experience of these alloys. A novel high Molybdenum, high silicon alloy was developed and patented for severe corrosive environments and patented. This solution combined the inherent properties of such fused coatings such as diffusion bonding, zero through porosity with improved performance over even welded 626 alloys. The increasing demands of waste incineration environments are leading to new developments.

EuTronic® Arc Wires: Through development in the early 1990s with leading power companies and high temperature wear institutes a family of iron-based high temperature boiler coating alloys was developed for arc wire spraying. Today these solid industrial references are being used for new alloy development, spurned by improvements in application equipment and increasing performance demands.

HVOF: The unique quality and properties of HVOF are attractive to boiler coating. The experience gained in arc wire and powder alloy developments is being modified to bring a new generation of Fe and Ni alloy powders for HVOF spraying.
