These AISI 4340 Steel Bars are mainly used in power transmission gears and shafts, aircraft landing gear, and other structural parts. Superior quality nickel chromium molybdenum alloy steel is used in manufacturing these bars. Widely used in oil & gas industry, these bars have high tensile strength. Offer toughness and high strength in the heat treated condition; these bars are usually supplied under quenched and tempered condition. These bars can be easily machined using all conventional techniques. Feature good ductility and formability in the annealed condition, these bars can be bent or formed by pressing or spinning in the annealed state.
