Effects of High Yield Ratio on Material Properties of Pipeline Steel

, 2011
The nominal yield ratio, true yield ratio and static toughness of five materials X80, X65, X60, X46 and Q235 have been tested in this paper. The yield ratio of pipeline steel is rising with the increase of strength level, which is inevitable for the high

Effect of Applied Potentials on Stress Corrosion Cracking Susceptibility of X80 Pipeline Steel in Simulated Soil Solution

, 2010
The stress corrosion cracking susceptibility of X80 pipeline steel was investigated in a simulated soil solution using slow strain rate tensile (SSRT) tests. The different potentials were applied in the tests.
