Abstract
520,024. Alloys. INLAND STEEL CO. July 8, 1938, Nos. 20301 and 20302. Convention dates, Nov. 30, 1937, and April 30, 1938. [Class 82 (i)] Lead is introduced into steel by adding it in subdivided form to a molten steel bath simultaneously with the pouring of the steel into the bath, the consequent agitation of the steel serving to disperse the lead in the steel. The lead may be added as metallic lead, for example in pieces such as shot, or it may be added as litharge, galena, lead phosphate, lead and iron sulphides, or any of the following alloys : a 1 : 1 : 1 lead-tinantimony alloy; a lead-iron-sulphur alloy; or lead alloys containing the following elements : 40 or 1À5 per cent. of tin ; 66 per cent. of copper and 2 per cent. of tin ; 0À6 per cent. of calcium ; 3 per cent. of bismuth ; 1À1 per cent. of arsenic ; 0À5 or 1À6 per cent. of cadmium; 0À1 per cent. of tellurium ; 1À7 per cent. of antimony ; 0À1 per cent. of lithium; 0À3 or 0À9 per cent. of zinc; 0À3 per cent. of sodium; 0À3 per cent. of magnesium. Specifications 519,572 and 519,615 are referred to.
