INVESTIGATION OF SUSCEPTIBILITY OF HIGH STRENGTH MARTENSITIC STEEL ALLOYS TO STRESS CORROSION

Abstract

The stress corrosion susceptibility of several high strength steels was evaluated by alternate immersion testing in a 3.5 per cent salt solution. The variables studied were material, grain direction, heat treatment, stress level, surface preparation, protective coatings, and variations from holes and fasteners. The test materials were 4330M, 4340, 4340M, H-11, AM 350, and AM 355 steels. Notch tensile testing and x-ray diffraction measurements of residual surface stresses were also carried out. (Author)
