    AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 steel from stock.

  • 4340 Alloy Steel Material Datasheet

    Alloy 4340 can be hardened by a heat treatment followed by an oil quench, or simply by working it while cold. 4340 has average density for a steel alloy, melts at a relatively high temperature (2,600 degrees Fahrenheit) and is malleable enough to be “cold worked,” or worked in a non heated state.
