Today hydrogen for use as fuel for vehicles is getting more and more attention as an alternative to vehicles using fossil-based fuels. Hydrogen is used in both electric fuel cell cars and in heavy vehicles using direct combustion of hydrogen. Such vehicles require stainless tubing for transport of the hydrogen and for bosses to composite tanks in addition to tubing and fittings in hydrogen fueling stations.

Strain Hardened Austenitic Corrosion Resistant Alloys’ Susceptibility to Hydrogen Induced Stress Cracking

Product Number: 51323-19235-SG

Author: Amrinder P.S. Dhillon, Xu Lu, Roy Johnsen, Ida Westermann

Several offshore field failures in recent years have been attributed to Hydrogen Induced Stress Cracking (HISC) of high strength, highly corrosion resistant Precipitation Hardened Nickel Alloys (PHNA’s) such as UNS N07716, UNS N07718 and UNS N07725.

Hence, HISC is a constant concern regarding subsea components subjected to high tensile stress, and the industry is searching for solutions to their technical needs: High strength corrosion resistant alloys (CRA’s) resistant to seawater (high Pitting Resistance Equivalent number (PREN)) but also resistant to HISC.

For PHNA’s, improved processing (chemical composition limits and processing temperatures) and improved quality control methods as well as refined acceptance criteria are all under consideration.
