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 In Stock Castle Metals SiteAlloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel. An additional grade of Alloy 4340 is Alloy E-4340.
4340 Alloy Steel Steel Bar EN24 817M40 DIN1.6582 34CrNiMo6. Application. 4340 Alloy steel mainly used in mechanical parts, automobile parts, cement plants, power plants, mobile cranes and earth-moving equipment, aerospace industry for structural parts of flaps assembly, fuselage and landing gear, propeller plane axles, etc.
4340 Steel - 4340 Steel Plate Pennsylvania Steel CorporationPennsylvania Steel Corporation offers an alternative to SAE 4340 alloy steel. We produce FLEXOR® steel to be similar if not superior in its mechanical properties to 4340 alloy steel. Taking this into account, it is suitable and can be utilized in most of the same applications as 4340 alloy steel.
