Hydrogen Stress Cracking

Materials and corrosion trends in offshore and subsea oil and gas production – Publication

August 8, 2017 by Mariano Iannuzzi

In this article, we discuss materials and corrosion research topics that could have a transformative effect on the business. In particular, we discuss how scientists and engineers could push the boundaries of existing technologies, learning from the experience gained by other industries such as the nuclear, aerospace, and defense sectors.

Sulfide stress cracking of nickel-containing low-alloy steels

September 29, 2014 by Mariano Iannuzzi

Low alloy steels with a nickel content greater than 1% are not allowed in sour service applications. This paper reviews the effect of nickel on the hydrogen embrittlement performance of low alloy steels.
