METHOD OF DETERMINING SUSCEPTIBILITY OF PIPE STEELS TO STRESS-CORROSION

摘要

FIELD: testing engineering. ;SUBSTANCE: method comprises affecting the specimen to be tested by hydrogen-containing corrosive agent, making stamps on the specimen by applying a load within 0.85-0.95 of the steel yield poi, determining coefficient of the irregularity of the surface microscopic deformation, and determining the susceptibility to stress-corrosion capability from the data obtained.;EFFECT: enhanced precision.;1 cl, 1 dwg
