Maraging Steel :-
1. Maraging Steel find applications as aluminum die casting dies, inserts, extrusion dies, forging dies, punches, cold hardening dies and dies holder.
2. Maraging Steel are low carbon, high nickel alloy steel , capable of attaining yield strength in excess of 185 MN/M2 in combination with wood fracture toughness.
Composition of Maraging Steel :
This Steel contain :
- Carbon C – 0.02%
- Nickel Ni – 18 %
- Cobalt Co – 8 %
- Molybdenum Mo – 5% , along with small amounts of Titanium and Aluminum as hardening agent. This alloy is martensitic in annealing conditions and acquires ultra high strength by aging treatment.
