TECHNICAL SPECIFICATIONS Aircraft steel D-6AC

MATERIAL CATEGORY: Ultra high strength 1520Mpa Asteel
MAIN FEATURES: D6AC VAC-ARC steel is a medium carbon, low alloy, ultra high strength 1471Mpa steel primarily designed for high strength structural applications
D6AC steel is produced by the consumable electrode vacuum arc remelting process to provide optimum cleanliness and preferred ingot structure, which in turn provide optimum transverse mechanical properties.
