UNS K93120 ASTM A579 AMS 6514 - Bar SAE AMS 6514 and AMS 6521 (UNS K93160) - Sheet, Strip, Plate MIL S 46850, MIL S 13881 Werkstoff Nr. 1.6358 and 1.6354 Also known as Type 300, Maraging 300, C300 Vdimor 300 Vascomax C300

Maraging Steel 350 (VascomaxC350) is a low carbon Maraging steel, cobalt strengthened to give excellent toughness and ductility. The alloy has good fabrication characteristics, which include a low rate of work hardening, good Machinability and weldability, and a very simple heat treatment process. The applications are missile and rocket motor cases, landing and take off gear, tooling, high performance shafts, gears, fasteners and munitions.

Maraging305 ( Vascomax 350 ) Roundbars,wires,sheets and plates Available.
