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.
