Maraging C300 Typecial mechanical properties

Material	0.2 % Yield Strength ksi	Ultimate Tensile Strength ksi	Elongation in 4D(%)	Reduction of Area %	Hardness Rc
Maraging 300, Solution Annealed 1500° F (816°C), 1hr, AC	120	150	16	70	30

Machining of Maraging C300
Maraging steel in the annealed condition is comparable to 4340. However, when maraging is aged, the type of cutting tool and speeds change. Rigid equipment, firm tool supports, sharp tools and abundant coolant are essential.

Welding of Maraging C300
Maraging is weld able without preheat, in both the annealed and aged condition. Only an aging heat treatment is needed to restore in the weld.
