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. 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.
