Abstract: A method for manufacturing a guide roller for hot wire rolling includes the steps of providing a guide roller made of an Al alloy, the guide roller including a wire guiding surface, and applying a coating onto at least a part of the wire guiding surface by a metallic wire Direct Energy Deposition (DED) operation and/or a metallic powder DED operation.

Abstract: The present invention relates to a continuous caster roll for a continuous casting machine, having; a base portion and an overlay portion made of martensitic stainless steel. The steel of the overlay portion includes 12-14% by weight Cr (chromium), and the steel further includes 0.2-0.5% by weight Nb (niobium) which is a stronger carbide former than Cr, such that Cr will be kept in solid solution in the overlay portion. The balance being Fe (iron), other alloying elements and normally occurring impurities. In addition, a method to manufacture the continuous caster roll is disclosed, wherein the overlay portion is applied by any of weld cladding or laser cladding.
