Maraging 350/Maraging C350/Vascomax C350™

Common Trade Names: Vascomax® 350

Maraging C350™ is a nickel-maraging alloy. Maraging C350™ is a relatively soft but tough material, therefore, readily machined and formed. The aging process of Maraging C350™ raises the hardness to a level sufficient for many tooling applications.Typical applications of maraging steels are missile and rocket motor cases, wind tunnel models, landing gear components, high performance shafting, gears, and fasteners.

Available forms are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.
