Aircraft steel D6AC / D6A
TECHNICAL SPECIFICATIONS - Grade Aircraft steel D-6AC / D-6A
MATERIAL CATEGORY: Ultra high strength 1520Mpa Alloy steel
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.
OFFICIAL TEST CERTIFICATE: issued by TUV - SGS - BV
