Latrobe Lescalloy® 6305 VAC-ARC ; High Strength Alloy Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Carbon Steel; High Carbon Steel

Material Notes: LESCALLOY 6305 VAC-ARC steel is a modified 4140 steel with higher molybdenum and a vanadium addition. The alloy steel is generally used in the 160/180,000 psi tensile strength range obtained with an 1100°F temper where good toughness is critical, such as jet engine shafts. It is produced by the consumable electrode vacuum arc remelting process to provide optimum cleanliness and preferred ingot structure.
