Special Steel, Maraging 250

This grade is a low carbon Maraging steel 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. The applications are Missile components, tooling and Jet Engine Shafts.
