Latrobe Marvac 300 VIM-VAR ; 10 in. High Strength Maraging Steel

MARVAC 300 VIM-VAR is a low carbon maraging steel capable of 270,000 psi minimum yield strength, coupled with excellent toughness and ductility. The alloy has good fabrication characteristics, which include a low rate of work hardening, good machinability and weldability, and a very simple heat treatment process. Marvac 300 is produced by vacuum induction melting followed by VAC-ARC remelting. This approach provides superior cleanness and a preferred ingot structure to enhance transverse mechanical properties. Marvac 300 is supplied in the solution annealed condition.Solution annealed and aged at 900°FInformation Provided by Timken Latrobe Steel.Timken sold Latrobe in December 2006.
