Abstract

LESCALLOY HP 9-4-30 VAC-ARC is a low-alloy, high-strength steel with a high nickel content to promote toughness. It was designated for high hardenability and good weldability. It is produced by the vacuum-consumable-electrode process to insure cleanliness and provide a preferred ingot structure. 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-343. Producer or source: Latrobe Steel Company.
