Latrobe Lescalloy® HP 9-4-30 VAC-ARC ; 5.75 in RCS Billet Size High Strength Alloy Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Low Alloy Steel; Carbon Steel; Medium Carbon Steel

Material Notes: LESCALLOY HP 9-4-30 VAC-ARC steel is a low alloy, high strength steel with a high nickel and cobalt content to promote toughness. The alloy has been designed to have high hardenability, good weldability and excellent fracture toughness. It is typically used in the 220/240,000 psi (1517/1655 MPa) tensile strength range. Lescalloy HP 9-4-30 VAC-ARC steel is produced by the consumable electrode vacuum arc remelting process to provide optimum cleanliness and preferred ingot structure.

Normalized at 927°C; Austenitized at 829°C for .5 hour
