Maraging 300 alloy is a very high strength iron base, nickel , molybdenum, cobalt alloy. It may be age hardened to a strength level of 300 ksi ultimate with a hardness on the order of Rockwell C 53.
APPLICATIONSUsed for very high strength structural applications such as aircraft land gear components.
MACHINABILITYMachinability is good, similar to that for 304 stainless steel.
FORMINGMaraging 300 steel has good ductility and is readily formed by conventional methods.
WELDINGThe alloy is weldable by conventional methods, much the same as for 304 stainless steel.
HEAT TREATMENTMaraging steel is not heat treatable for hardening except by aging. See “Aging”.
FORGINGThe alloy may be forged as for stainless 304 alloy.
HOT WORKINGHot working of maraging steel may be done at temperatures in the 500 to 200 F range. Prolonged exposure at these temperatures may result in some age hardening. However a full aging treatment should be given.
COLD WORKINGThe alloy is readily cold worked by conventional methods.
ANNEALINGAnnealing, if required after cold working, can be done at 1900 F followed by rapid air cooling.
AGINGThe high strength and hardness properties are a result of an aging heat treatment at 900 F
TEMPERINGNot applicable to this alloy.
HARDENINGMaraging 300 hardens by cold working and by aging – see “Aging”.
