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.
