4330 steel (also known as AISI 4330 steel) is a hardened iron and nickel based alloy with high strength, hardness, toughness and tensile properties. Popular in the oil, gas, and mining industries, 4330 features solid formability and machinability with terrific cold working characteristics. Other applications for 4330 include aircraft and power transmission components, machinery, and bolting. Standard specifications for 4330 alloy steel include AMS 6415 and more.
