Latrobe Lescalloy® D6AC VAC-ARC High Strength Alloy Steel
Categories:	Metal; Ferrous Metal; Alloy Steel; Low Alloy Steel; Carbon Steel; Medium Carbon Steel
Material Notes:	LESCALLOY D6AC VAC-ARC steel is a medium carbon, low alloy, ultra high strength steel primarily designed for high strength structural applications requiring strength leaves up to 280,000 psi. This alloy provides a high yield strength to tensile strength ratio, combined with good ductility. A tough and fibrous fracture is exhibited to as low as -210°F in impact testing; also the notch toughness is excellent. It has been selected for fracture toughness critical applications at a variety of strength levels. The deep hardening characteristics of D6AC steel make it applicable for fairly large sections. Lescalloy D6AC VAC-ARC 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. Heat Treatment - Austenitized at 1650°F. Oil quenched and air cooled, or salt quenched at 400-425°F for 10 minutes and air cooled Information Provided by Timken Latrobe Steel. Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
