Abstract

In a process of treating iron and steel to improve their heat-resisting and/or physical qualities, the iron &c. is embedded in a mixture of aluminium and/or magnesium, an inorganic carbide, sal ammoniac or its equivalent such as zinc or manganese chloride and a chromium chloride and heated to 650-1150 DEG C. The carbides used are carborundum or calcium strontium or barium carbides. In an example, the mixture comprises 50 parts of finely-divided aluminium, 40 of carborundum, 7 of anhydrous chromic chloride and 3 of sal ammoniac. Reference has been directed by the Comptroller to Specification 337,562, [Class 72].
