Effect of Structural State on Tendency Towards Stress Corrosion Cracking of Ultralow-Carbon Martensitic and Low-Alloy Pipe Steels

Effect of Structural State on Tendency Towards Stress Corrosion Cracking of Ultralow-Carbon Martensitic and Low-Alloy Pipe Steels

Mechanical properties as well as crack resistance and stress corrosion cracking (SCC) resistance parameters of ultralow-carbon martensite steels (ULMS) type 05H2G2B and HSLA pipe steel 10G2FB with a different structures depending on processing are investigated. It is shown that despite a higher stre...

Zusammenfassung:Mechanical properties as well as crack resistance and stress corrosion cracking (SCC) resistance parameters of ultralow-carbon martensite steels (ULMS) type 05H2G2B and HSLA pipe steel 10G2FB with a different structures depending on processing are investigated. It is shown that despite a higher strength level, SCC resistance of ULMS steel is 25–30% higher than for HSLA steel with ferrite-perlite structure and close to that for this steel subjected to quenching and tempering.
