Latrobe Lescalloy® M50 VIM-VAR High Performance Bearing Steel
Categories:	Metal; Ferrous Metal; Alloy Steel; Carbon Steel; High Carbon Steel
Material Notes:	LESCALLOY M50 VIM-VAR steel is a through-hardening grade with high hardness and high compressive strength at elevated temperatures. It is produced exclusively as a double vacuum melted produced using vacuum induction melting plus VAC-ARC remelting. This VIM-ARC process provides the optimum in control and reproducibility of chemistry, micro cleanliness and superior fatigue resistance. Information Provided by Timken Latrobe Steel. Timken sold Latrobe in December 2006. They are now Latrobe Specialty Steels Co.
