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

Product Number: 51323-19235-SG

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.

The Susceptibility Of Spheroidal Graphite Cast Iron To Hydrogen Induced Stress Cracking

Product Number: 51322-17796-SG

Cast Iron with its ancient history, traced back to 6th century BCE1, has been used for centuries to anything from manhole covers & fire hydrants to bridges. However, the development of Spheroidal Graphite Cast Iron (SGCI) or Nodular Cast Iron, in the 1940’s, with resulting improvement in mechanical properties such as ductility and fracture toughness, paved the way for further growth in industrial usage of cast iron.² The material has been adopted by several industries such as automotive-, nuclear-, and wind turbine industry. During the last decade, SCGI has gained increased attention as construction material for subsea equipment in offshore oil & gas production, mainly competing with welded and bolted steel assemblies.
