1 3/4" MAR350 MARAGING / VASCOMAX Type Steel Bar MIL-S-46850 *Sold Per Inch*

Description

1 3/4" MAR350 MARAGING / VASCOMAX Type Steel Bar MIL-S-46850 *Sold Per Inch*
I have one 4 foot length available of unknown brand Maraging bar stock
MIL-S-46850
that comes hardened to approximately RC40. This material turns beautifully with carbide but I have not tried it with HSS.
I can't make any statements about its suitability for any particular application nor do I have material certs so please consider that when you purchase. This can be ordered cut to your specifications by the inch.
* Price as shown is per inch, please order multiple quantities for your choice of length or contact me to place your order.
MARAGING (C) 350
General:
Maraging is a 18% nickel, cobalt strengthened steel (C-type), with excellent mechanical properties, workability and heat treatment characteristics.
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.

Material Melt Method:
Maraging melt method is a VIM (Vacuum Induction Melt) + VAR (Vacuum Arc Remelt)
As Shipped Condition:
Maraging is supplied in the annealed and descaled condition. The alloy is very tough, relatively soft
(38 Rc Max.)
, therefore, readily machined and formed
.

Heat Treatment Aging Process: (Non Die Casting Applications)
Material is to be heat treated to 900 F +/- 10 holding at temperature for 6 hours then cooling at room air temperature. During the aging treatment maraging shrinks uniformly and predictably on all dimensions .001 in/in
Heat Treatment Aging Process: (Die Casting Applications)
Following the rough machining of the die, anneal at 1500-1525 F for 1 hour per inch of thickness is recommended. After finish machining, an aging heat treatment of 980-1000 F for 6 hours is recommended.
Machining:
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:
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.
Standards:
