Abstract
579,927. Alloys. CLIMAX MOLYBDENUM CO. April 21, 1942, No. 5353. Convention date, March 6, 1941. [Class 82 (i)] Iron or steel alloys containing tungsten and silicon are produced by adding a preformed tungaten silicide to molten iron or steel, the temperature of the latter being, sufficient to dissolve the silicide. The silicide may be added to a blast furnace as part of the charge or to the iron or steel in a ladle and a mixture of tungsten silicides with or without an excess of silicon may be used. Other alloying ingredients such as molybdenum, chromium and nickel may be added with the silicide. When molybdenum is used, it is usually added in the form of ferro-molybdenum or calcium molybdate. Reference has been directed by the Comptroller to Specification 151,974, [Class 82. (i)].
