Abstract (en)

[origin: WO9533080A1] An iron-chromium-boron alloy, suitable for the production of tools for the manufacture of glass articles, and a tool made from the alloy, has a composition of from 1 to 20 wt.% chromium and from 0.5 to 3 wt.% boron. The composition optionally contains carbon subject to carbon in excess of 1.0 wt.% being bound by at least one strong carbide forming element in a carbide and/or carbo-boride phase, with the alloy otherwise optionally including the at lest one carbide forming element. The composition also optionally contains one or more of silicon up to 3 wt.%, aluminium up to 0.2 wt.%, manganese up to 2 wt.%, nickel up to 3 wt.%, copper up to 3 wt.% and molybdenum up to 5 wt.%. The balance, apart from incidental impurities, is iron.
