Abstract

An alloy steel, for producing artificial jewellery and containing 8-18 per cent Cr, 8-18 per cent Ni, 1-4 per cent Cu, not more than 1 per cent C, optionally up to 1 per cent Mn and up to 1 per cent Si and the remainder iron and impurities, has the proportion of copper in the steel substantially equal to but not greater than the limit of the solubility of the copper in the steel. Specifications 498,726, 577,892, 583,848 and 630,753 are referred to.
