300M VAR Premium Aircraft Centerless Ground Normalized and Tempered Alloy - Rounds
300M VAR Premium Aircraft Alloy
(E4340 Modified)
This steel is a chromium nickel molybdenum alloy similar to 4340, but modified by the addition of vanadium and a higher silicon content. The silicon acts to displace the 500°F temper embrittlement range to higher temperatures. The overall alloy content acts to produce higher strength levels without the necessity of increasing the carbon content. Thus, this alloy offers a combination of toughness and ductility at high strength levels. It is a deep hardening steel with excellent torque properties. It has high fatigue and creep characteristics and maintains its strength at moderately high temperatures.
The grade is available as a consumable electrode vacuum remelted product. This insures a steel of the highest quality with excellent transverse ductility and toughness at high strength levels. It also insures the non-metallic cleanliness of this alloy meeting AMS 2300, thus making it most suitable for the fabrication of parts subjected to magnetic particle inspection.
