Evaluation of High Strength Steels for Heavy Section Applications.

Abstract

Static and dynamic properties of these high strength steels were determined: Marage 250, Marage 300, HP 9 Ni-4 Co-45C (martensitic), HP 9Ni-4Co-45C (bainitic), 4340 (260 to 280 Ksi), 433OV and Hy-Tuf. The properties investigated were: tensile and notch tensile; axial fatigue, notched (K sub t = three) and unnotched (K sub t = one); fracture toughness, face crack and through crack; Charpy V-notch impact; resistance to hydrogen embrittlement cracking; sustained load and resistance to stress corrosion cracking.
