Höganäs AB, Sweden, launches its new Rockit 606/706 welding powders, which prolong component lifetime in tough wear environments such as the oil & gas and mining & construction industries. The new welding powders feature a unique combination of high impact and abrasive wear resistance, and are robust to process variations. Rockit 606 is recommended for laser cladding, while Rockit 706 is the suitable choice for the plasma transferred arc (PTA) welding process.
“Rockit 606/706 are iron-based and have a martensitic structure with finely dispersed vanadium carbides,” says Hans Keller, President of Product Area Surface & Joining Technologies at Höganäs. “This combination provides excellent wear characteristics and a consistent high hardness, together with a good impact resistance. The materials have excellent welding properties and achieve a smooth deposit.”
“Rockit 606/706 applied on wear plates for dozer blades during field tests showed that cladding material costs can be reduced by 30%, while maintaining the same lifespan achieved with other industry solutions,” says Martin Lohrman, application specialist at the Höganäs ArcX coatings center in Johnstown.
With this product launch, Höganäs adds new materials to the Rockit family, a series of specialty alloys to extend component lifetime. “We are building on the success of the previously launched Rockit 401 material, a sustainable solution to replace hard chrome plating. The material has quickly become a standard in the mining and construction industry,” says Mr. Keller.
Rockit is part of Höganäs’ extensive portfolio of surface coating solutions that grew rapidly through its acquisition of H.C. Starck’s Surface Technology division in 2018.
