FEASIBILITY OF DEVELOPING AN HY-180/210 WELDMENT.
Abstract
Base-metal studies were concentrated on an evaluation of the potential of maraging steels as HY180/210 baase metals. The results obtained to date indicate that the maraging steels, particularly in 1- to 4-in. thick plates, exhibit poorer notch toughness than quenched and tempered steels at yield strengths in the range 150 to 200 ksi. The embrittlement causing the reduced notch toughness is being intensively investigated. Although studies to determine the cause and elimination of embrittlement will be continued, studies on quenched and tempered steels, on steels strengthened by a combination of carbon martensite and age hardening, and on spedial processing techniques such as ausforming and rapid heat treatment will be accelerated.
