High Elasticity Martensite Stainless Steel Maraging300 Rod Forging Cold Wire
Maraging 300 is a 18% nickel, cobalt strengthened steel (C-type), with excellent mechanical properties, workability and heat treatment characteristics. It is also called 18Ni300.
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 compositions of Martensite Stainless Steel Maraging
Solid solution temperature is 815~830℃, oil cold or air cold (heating time, salt bath furnace 1min/mm, air furnace 2~2.5min/mm) and the hardness is 28HRC.
The aging temperature of Maraging250 and Maraging300 steel is 480℃ and the holding time of 3h, hardness is 43HRC; holding time of 6h, hardness of 52HRC.
The limitation temperature of Maraging350 steel is 510℃, and the limitation time of 6h, hardness is 57~60HRC.
The main production processes are smelting, heat processing, cold processing, welding, heat treatment and surface treatment.
