High Energy Rate Forming (Pneumatic-Mechanical) of Types 200, 250, and 300 18% Nickel Maraging Steel

摘要

High energy rate forming with a pneumatic-mechanical press of types 200, 250, and 300 18% nickel maraging steels followed by heat treatment yielded optimum mechanical properties when forged to a 75% reduction at 1900 F. These properties were slightly superior to those observed for the as-received and heat-treated materials. (Author)
