Abstract

A ferritic alloy steel has the following composition:-C 0.03-0.2 per cent., Si 0.1-1.5 per cent., Mn 0.1-2.0 per cent., Cr 3.5-8.0 per cent., Ti 0.05-0.4 per cent., V 0.01-0.5 per cent., B 0.001-0.05 per cent., W 0.4-2.5 per cent. and/or Mo 0.3-1.5 per cent., the maximum total content of W and Mo when both are present being 3.0 per cent., Fe, and incidental impurities, the remainder. The alloy may also contain Ni up to 2.0 per cent. The Provisional Specification describes also an alloy from which B is absent and in which the range of proportions C, Cr, Ti and W are C 0.03-0.25 per cent., Cr 3.5-9.0 per cent., Ti 0.05-0.5 per cent., W 0.5-2.5 per cent., the ranges of proportions of the other constituents being as stated above.
