Abstract

A steel article consists of an alloy of preset elements and has a micro-structure obtained by manufacturing steel which involves spray forming an ingot. The micro-structure contains 8-15 vol% of carbides of MC-type where M consists of vanadium, of which carbides at least 80 vol% have a rounded shape and a size of 1-20 mum in the longest extension of the carbides. The steel article consists of an alloy containing carbon (in weight% (wt.%)) (1.2-2), silicon (0.1-1.5), manganese (0.1-2), nitrogen (up to 0.2), sulfur (up to 0.25), chromium (4-8), molybdenum and tungsten in a preset composition (Mo+W/2) (0.5-3.5), vanadium (5-8) and remainder of iron along with unavoidable impurities. The steel has a micro-structure obtained by manufacturing steel which involves spray forming an ingot. The micro-structure contains 8-15 vol% of carbides of MC-type where M consists of vanadium, of which carbides at least 80 vol% have a rounded shape and a size of 1-20 mum in the longest extension of the carbides.
