TECHNICAL SPECIFICATIONS - ASTM A579 Gr.13
MATERIAL CATEGORY: Ultra high strength 1450 Mpa alloy steel
MATERIAL DELIVERY CONDITION: Quenched and tempered
MAIN FEATURES: A579 series VAC-ARC steel is a medium carbon, low alloy, ultra high strength 1000Mpa steel primarily designed for high strength structural applications
A579 series 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.
