Abstract
1465064 Deep drawing steel BRITISH STEEL CORP 9 Aug 1974 [14 Aug 1973] 38479/73 Heading C7A A deep drawing steel, suitable for vitreous enamelling without "carbon boiling" or "fish scaling" contains Basic oxygen steel, killed with up to 0À1% aluminium is cast, and the inclusion-shape control agent e.g. Cerum, is added either during casting or in the mould. The addition spheriodizes the FeS and MnS inclusions improving the formability of the steel and prevents "fish-scaling" due to hydrogen diffusion to the steel/enamel interface on standing after conventional enamelling. The low carbon content prevents "carbon boiling" due to the formation of CO.
