Metallurgical specifications of Plates and Strips of Steel Maraging 250

General Characteristics
Maraging 250 VIM-VAR is a low carbon maraging steel capable of 240,000 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. Maraging 250 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. Maraging 250 is supplied in the solution annealed condition.
