AISI 4330, is a fine-grained, medium carbon, chromium-nickel-molybdenum alloy steel. AISI 4330V is a modification of the 4330 alloy steel grade, with hardenability and other characteristics improved by the addition of vanadium. Alloy Steel 4330V offers good formability which is used for those that require a good combination of strength and impact resistance.
