Introduce

Maraging steel grades C200 series and C300 series steel is an age harden iron-nickel steel alloy, melted as VIM + VAR with ultra high strength and toughness. This steel material is easily machinable in the annealed condition prior to final heat treatment. Grade has improved fracture toughness from Maraging 300 series but slightly less strength. The unique properties makes it suitable for many critical aerospace applications.
