Commercial Supersonic Transport Program. Phase 2-C Report. High Strength Steel Evaluation For Supersonic Aircraft

Abstract

Forged billets of three vacuum melt heats of 4330 V-Modified, H-11 Modified, 9Ni-4Co-0.30C, 9Ni-4Co-0.45, and Maraging (18 percent Ni) 250 and two heats of 300M were evaluated to provide high strength steel alloy selection data for heavy section aircraft components. The evaluation included the following types of tests: tensile, precracked charpy impact, plane strain fracture toughness, stress corrosion, hydrogen embrittlement susceptibility, elevated temperature stability, and fatigue. The results of the testing are discussed and are related to alloy selection considerations.
