Product Introduction

Products Description

C300 Maraging Steel, also known as Type 300, is a slow cool, age hardening (maraging) steel. This type of precipitation hardening creates the exceptional strength and toughness that C300 is known for. As a result of these attributes and it’s crack resistance propagation, Maraging is often used for tooling, missile casings, and aircraft landing gear. Maraging C300 is composed primarily of iron with nickel, cobalt, and molybdenum being the other major chemical properties. Standard specifications for Maraging C300 include UNS K93120, ASTM A579 and more.

Maraging C300 is available in Bar (Rounds), Forging Billet ,Plate. For all stock availability contact Sales.

Maraging Steel Heat Treatment / Aging:

Maraging alloys are essentially carbon-free, a protective atmosphere is not required during annealing or aging. Material is supplied in the solution annealed condition with a hardness of 30/35 Rc. Typical heat treat time/temperature are listed below. Large cross sections should be aged for longer periods.

Temperature	Time	Resulting Hardness
900/925 °F	6 hrs	50/55 Rc

NOTE: A modified aging cycle is suggested for die casting applications for increased die life. The following thermal treatments have been used to obtain desirable characteristics for die casters. Following the rough machining of the die, anneal at 1500-1525 ºF for 1 hour per inch of thickness is typical. After finish machining, an aging heat treatment of 980-1000 ºF for 6 hours is typical.
