Abstract

LESCALLOY UT-19 VAC-ARC is a premium quality carburizing steel with high hardenability. It is produced by vacuum are remelting (VAR) to provide a preferred ingot solidification and superior microcleanliness. It is used for aircraft gears, pinions and other carburized parts that require a high minimum core hardness. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-394. Producer or source: Latrobe Steel Company.
