This research effort was designed to evaluate stress-oriented hydrogen-induced cracking (SOHIC) behavior of a broad range of advanced plate steels (0.002 wt% sulfur) that were not produced to enhance resistance to cracking in wet H2S environments. Test results indicated that SOHIC resistance was adversely affected by microstructural (ferrite/pearlite) banding. However, additional factors also played a role in determining SOHIC behavior.

Today a need for a C125 Sulfide Stress Cracking (SSC) resistant material exists with the development of High Pressure/High Temperature (HP/HT) oil and gas fields. This paper focuses on the SS resistance of industrial heats.
This paper will discuss some of the reasons why some Owner/Operators are choosing to invoke NACE MR0175-20021 instead of NACE MR0175/ISO 15156. Examples of exceptions taken will be examined. And cost issues involved in meeting MR0175/ISO 15156 will be presented.
Sour service behavior of a 110ksi material was investigated in a range of production environments. Slow strain rate tests were performed at a strain rate of 510-7/s, in sweet as well as in sour production environments. The strain to failure in sweet environments is lower than the in-air values and is substantially lower in the presence of H2S.
A corrosion cracking assessment evaluated a 13Cr-5Ni-2Mo 110 ksi grade martensitic stainless steel as a potential well tubing material for oil and gas production from Gulf of Mexico reservoirs. Also, Stress Corrosion Cracking at low H2S/low temp/high acidity (pH<3.5) was tested by Cyclic Slow Strain Rate.
Lean duplex stainless steel (LDSS) can provide mechanical properties similar to that of duplex stainless steel (DSS) and is less expensive. The focus of this work was to assess the stress corrosion cracking (SCC) and SCC susceptibility of DSS and LDSS in chloride-containing sour water conditions.
The aim of this test program is to provide technical data to support the replacement of austenitic flexible pipe carcass, at Campos Basin, by low cost materials with suitable mechanical properties and corrosion resistance when the field conditions turn too aggressive to carcass materials in operation.
This paper presents environmental performance data on welded nickel alloy under high temperature, high pressure, ‘ultra-sour’ conditions. Welded coupons of nickel alloy UNS N06625 were subjected to three levels of nominal stress and tested for 30 days.
Subsea flowlines and risers experience fatigue cycles due to thermal and/or pressure transients or vortex induced vibration (VIV). Tests were performed under constant stress intensity factor (K) levels, in a mildly sour environment and in seawater under cathodic protection to understand the difference in the CRG.
The paper summarizes the theoretical and test programs to validate the aluminum cladding solution – developed to overcome sulfide stress corrosion problems in high strength steel armors in H2S/CO2 containing environment.
To explore if the sour service performance gap between SMSS tubular and bar stock could be overcome, work was conducted to optimize the performance of 110ksi specified minimum yield strength UNS(1) S41426 bar product.
The paper describes the development of the methodology for the full ring, full thickness 4-point bend (4PB) and large scale DCB specimens and the results obtained from these tests.
