Abstract

669,470. Stainless steel alloys; annealing. ALLOY RESEARCH CORPORATION. July 16, 1947 [Sept. 6, 1946], No. 19022/47. Classes 72 and 82(i) A chromium-nickel stainless steel contains a chromium-like component consisting of Cr, Al 0.5-2.5 per cent, Si from incidental amounts up to 2.0 per cent and possibly Mo up to 3.0 per cent, the sum of the Cr content, Al content exceeding 1.0 per cent, Si content exceeding 1.0 per cent and the Mo content being defined by the abscissae of the area ABCD of the diagram; a nickel-like component consisting of C 0.02- 0.12 per cent, Mn from incidental amounts up to 8.0 per cent and Ni not less than 3.5 per cent, the sum of the Ni content, 20 to 30 times the C content and one half the Mn content being defined by the ordinates of the area ABCD of the diagram; and the remainder Fe and impurities. The alloy may also contain S or Se or both up to 0.5 per cent in total and P may be present up to 0.04 per cent. The alloy may be annealed at 1800-2000‹F., quenched, subjected to treatment below -30‹F. and heated at 750- 1000‹F. for sufficient time to obtain a substantial increase in hardness. Specifications 669,468 and 669,469 are referred to.
