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. Service Steel Aerospace stocks Premium Aircraft Quality produced double melted in an Electric Furnace, followed by VAR, or Vacuum Arc Remelt (also known as CEVM, or Consumable Electrode Vacuum Arc Remelting). This results in a much cleaner steel meeting the magnetic particle test requirements of AMS-2300. It is a steel of the highest quality with excellent transverse ductility and toughness at high strength levels. It has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. Standard Aircraft Quality air-melted AMS 6414 Air Melt material is available on request. 4340 ESR, or Electroslag Remelted material is also available on request.
