    4340V high tensile steel in AMS 6414 specification is a high-grade alloy steel, enriched with Chromium, Nickel, and Molybdenum, designed to be heat-treated for superior strength. This specification caters to the highest aircraft-quality standards, available in bars, forgings, mechanical tubing, and forging stock. The steel undergoes a dual melting process, beginning in an Electric Furnace and followed by Vacuum Arc Remelt (VAR), also known as Consumable Electrode Vacuum Arc Remelting (CEVM). This method ensures a cleaner and higher quality steel, meeting the rigorous magnetic particle inspection criteria of AMS-2300.

    Known for its exceptional quality, 4340V AMS 6414 steel boasts excellent transverse ductility and toughness at heightened strength levels, along with impressive shock, impact, wear, and abrasion resistance in its hardened state. Common applications include jet engines, landing gear and gear boxes.
