Alloy 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 Steel Alloy - Bars, Blocks, Rings, Sheets | Aero-Vac 4340 steel, a chrome nickel-moly alloy, comes in a variety of forms and conditions and is widely used for high stress parts. 4340 steel flat bar 4340 Flat Bar: AMS 6414, AMS 6415 4340 steel flat bar 4340 Alloy Rod & Bar Supplier - Air Melt, Hot Finished 4340 steel flat bar 4340 alloy steel bar is used heavily in the aerospace industry due to its ultra-high strength. When heat treated it is known for its toughness while preserving good fatigue strength. For highly stressed parts it is excellent choice.


4340 VAR AMS 6414 is a low alloy Chromium-Nickel-Molybdenum steel capable of being heat treated to high strength levels. This specification is for a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.

Ordinary medium and thick steel plate 4340 steel flat bar is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.
