Abstract

1,204,038. Alloy steel. INTERNATIONAL NICKEL Ltd. Feb. 9, 1968 [Feb. 20, 1967], No. 6581/68. Addition to 1, 45, 000. Heading C7A The steels disclosed and claimed in claims 1 and 2 of Specification 1, 045, 000 (as amended) are modified in one or both of the following respects: - (a) The Al content is from 0À2 to less than 0À5% and (b) The sum %Ni + 0À8% Cr is 19 to less than 19À5% The steels may be heat-treated as in 1, 045, 000. In an example the hot worked steels are solution treated at 815‹ C., air cooled, refrigerated in dry ice to -73‹ C. and then aged at 480‹ C, with the optional step of cold working before or after ageing.
