High strength low alloy steels and hydrogen – Presentation

November 8, 2015 by Mariano Iannuzzi

I was invited by Prof. Roy Johnsen and the Norsk Forening for Vedlikehold committee to give a presentation at the 2015 Robust materialvalg i oljeindustrien conference, which was held in Stavanger on October 27-28.

The title of the lecture was “High strength low alloy steels and hydrogen: microstructure, strength, and hardness limits”. In this presentation, we discussed the origins of the famous 22 HRC hardness limit in NACE MR0175, posteriorly adopted by the current ISO 15156-2 standard. We also talked about the environmental boundaries of corrosion resistant alloys as presented in ISO 15156-3 and the limitations of the approach. Finally, we discussed the future of materials for subsea oil and gas production, and the need for a common industry approach for qualification testing of low alloy steels with strength and hardness outside ISO 15156-2 option 1 limits.

The presentation is embedded below.
