Material Notes:

LESCALLOY 4330+V VAC-ARC steel is a modification of 4330 steel with hardenability and other properties improved by the addition of vanadium. It is a low alloy steel capable of being heat treated to high strength levels. The alloy is primarily used in the 220 to 240 ksi (1517-1655 MPa) strength range. The comparatively low carbon content of the alloy makes it particularly useful in applications involving shock loading or stress concentration. LESCALLOY 4330+V VAC-ARC steel is produced by the vacuum consumable electrode melting process to provide optimum cleanliness and preferred ingot structure.Samples were austenitized at 1600Â°F for 1 hour and oil quenched.Information Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
