Maraging300 C300 Martensite Stainless Steel with High strength and
elasticity
Maraging is a series of martensite stainless steel with nickel
content at 18% by adding cobalt to improve the performance. This
series of Stainless Steel have excellent mechanical properties,
processing properties, and heat treatment properties. It is also
called 18Ni300.
Production process:
The main production processes are smelting, heat processing, cold
processing, welding, heat treatment and surface treatment.
Applications
Typical applications for maraging include missile and rocket motor
cases, landing and takeoff gear, munitions, aerospace, extrusion
tooling, die casting, high performance shafting, gears and
fasteners.
Chemical composition of Maraging:
