Latrobe Lescalloy® 300M - HS VAC-ARC High Strength Alloy Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Low Alloy Steel; Carbon Steel; High Carbon Steel

Material Notes: LESCALLOY 300M-HS VAC-ARC steel is a modified 4340 steel with added silicon allowing for use of a higher tempering temperature. The steel has high hardenability and strength with good ductility and toughness in heavy sections, which make it suitable for aircraft landing gear, flap tracks, and other structural components. This variant has been developed for applications requiring 287 ksi (1979 MPa) minimum tensile strength through stringent control of chemistry and processing parameters. The enhanced properties of Lescalloy 300M-HS VAC-ARC permit the design of lighter aircraft components that exhibit equivalent load carrying capacities compared to standard 300M components. Vacuum arc remelting (VAR) is used to provide optimum cleanliness and preferred ingot structure.
