Effect of Pipe Steel Strength on Sulfide Stress Cracking Resistance
- 20 Downloads
Based on test results for low-alloy steel of strength categories X42–X70 the effect is established of loading and strength properties on sulfide stress corrosion (SSC) cracking resistance with uniaxial tension. A favorable effect is demonstrated for a reduction in loading factor and an increase in strength on an increase in steel SSC resistance. The level of steel yield and ultimate strengths providing good SSC resistance is determined.
