Abstract

A steel article consists of an alloy which consists in weight- %: 1.7-2.5; 0.1-2.0 Si; 0.1-2.0 Mn; max 0.2 N; max 0.2 S; 12 16 Cr; 2.1-3.5 (Mo+W/2); 5-8 V; max 0.1 Nb, balance essentially only iron and unavoidable impurities. The steel has a micro-structure obtainable by a manufacturing of the steel which comprises spray forming of an ingot, the micro-structure of which contains 14-25 vol-% carbides of mainly MC-type, where M substantially consists of vanadium, of which carbides at least 80 vol-% have a substantially rounded shape and a size in the longest extension of the carbides amounting to 1-10 mum, and M7C3-carbides, where M substantially consists of chromium, which carbides typically have a more elongated shape than the MC-carbides, of which MC-carbides at least 80 vol-% have a maximal extension amounting to 3-50 mum.
