FEASIBILITY OF DEVELOPING AN HY-180/210 WELDMENT.

Abstract

Preliminary studies on laboratory and production experimental maraging steels being considered as HY-180/210 steels have defined a number of fac tors that caused low notch toughness, and several laboratory and production maraging steels have recently been produced that have significantly improved notch toughness. Further modifications in composition and processing practices are being investigated that should lead to the development of maraging steels with even better notch toughness. Several quenched and tempered steels and a steel strengthened by a combination of carbon martensite and age hardening appear promising. Several nonconventional processing procedures also appear promising as methods for increasing strength with little or no loss in notch toughness. (Author)
