Abstract

In a modification of the invention of the parent Specification a forgeable ferritic alloy steel is produced by restricting the permissible range of proportions of C to 0.07-0.12 per cent. Within this range of C content the alloys may omit B and fall within the more restricted range of compositions as follows: C 0.07-0.12 per cent Si 0.5-1.0 per cent Mn 0.5-1.0 per cent Ni 0.5-1.5 per cent Cr 9.0-11.0 per cent Mo 0.4-1.0 per cent V 0.1-0.3 per cent Nb 0.2-0.6 per cent Ni 0.05-0.1 per cent Fe the remainder. The Nb may include residual amounts of Ta.
