11294 Susceptibility of Hydrogen Induced Stress Cracking of Duplex Stainless Steel at Elevated Temperature

Product Number: 51300-11294-SG

ISBN: 2011 11294 CP

Author: Roy Johnson, Bard Nyhus, and Ole Edvard Kongstein

Publication Date: 2011

$20.00

Experience has shown that stainless steels can suffer from Hydrogen Induced Stress Cracking (HISC) under cathodic protection in seawater. This paper presents results from a test program examining the HISC susceptibility of 25% Cr super duplex stainless steel (UNS S32750) at temperatures up to 150⁰C.

AMPP TR21524-2023, Commentary on Standards Development for Selection and Qualification of HSC-Resistant Materials in Subsea Service with Cathodic Protection

Product Number: AMPP TR21524-2023

Publication Date: 2023

$109.00

As a companion document to MR21525, this Technical Report provides results, review and commentary on many investigations of HSC and includes important literature data, references, background information, service experience and related standards that were utilized in the development of the AMPP MR21525. Most of the information in this Technical Report covers findings from HSC field experience and HSC data from brine/CP exposure tests or from other cathodic charging experiments. It is important to note, in the use of MR21525 and in the review of data contained herein, that HSC can also be induced from hydrogenating environments and conditions other than from just from CP exposure alone. A non-exhaustive list of such conditions is presented later in this Technical Report.

Comments On Standards Development For Selection And Specification Of Subsea Materials

Product Number: 51322-17491-SG

Author: Russell D. Kane

Publication Date: 2022

$20.00

In the oil and gas industry, the major standard for material selection today is ANSI¹/NACE² MR0175/ISO 15156 Parts 1-3. [1] While this standard deals extensively with environment cracking and its prevention for materials under exposure to production environments containing H₂S, CO2, chlorides, and sulfur, it does not include any guidance or material requirements for resistance to environmental cracking (such as hydrogen stress cracking – HSC, or otherwise) under variable subsea conditions that involve exposure to seawater with varying levels of cathodic protection (CP). ISO 21457 [2] provides further guidance for materials selection and corrosion control for oil and gas production systems but does not provide adequate coverage of the issue of environmental cracking in subsea applications with CP.

Susceptibility to Hydrogen Induced Stress Cracking of Alloy 718 and Alloy 725 Under Cathodic Polarization

Product Number: 51315-5597-SG

ISBN: 5597 2015 CP

Author: Gaute Stenerud

Publication Date: 2015

$20.00

A test project to examine the susceptibility of Hydrogen Induced Stress Cracking (HISC) has been executed. In this project hydrogen charged samples of Alloy 718 and Alloy 725 have been exposed under tensile stress to establish critical stress levels for initiation of HISC.

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

Product Number: 51322-17796-SG

Author: Veronika Djupvik, Cathrine Hartung, Atle H. Qvale, Roy Johnsen, Ida Westermann

Publication Date: 2022

$20.00

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.
