Carpenter Silicon Core Iron B-FM is melted in electrical arc furnaces to exacting chemical specifications and is carefully controlled in rolling and annealing practices to produce a fine-grained uniform quality magnetic core alloy. Silicon Core Iron B-FM has improved machining characteristics over Carpenter Silicon Core Iron B (see Alloy Digest Fe-90, April 1990). This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming, heat treating, and machining. Filing Code: FE-116. Producer or source: Carpenter.

Carpenter Silicon Core Iron "B" is melted in electric arc furnaces to exacting chemical specifications, and carefully controlled in rolling and annealing practices to produce a fine grained uniform quality magnetic core alloy. Silicon Core Iron "B" is not recommended for components which must be cold formed due to its high silicon content. This alloy was covered with 4 other silicon core irons in Fe-36, November, 1968. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on heat treating and machining. Filing Code: Fe-90. Producer or source: Carpenter.

ELASTUF 44 is a special analysis, electric furnace chromium, nickel, molybdenum alloy steel heat treated to Rockwell C42-46, and machinable. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on heat treating and machining. Filing Code: SA-72. Producer or source: Brown-Wales Company.
