04151 High Strength Fasteners for Subsea Applications

Product Number: 51300-04151-SG

ISBN: 04151 2004 CP

Author: Khlefa A. Esaklul, BP Exploration; John W. Martin, BP Amoco

Laboratory testing to qualify several materials for high strength fastener applications for two projects has shown that, in the presence of cathodic protection, nickel alloys 718 and 725 offer the best resistance to hydrogen embrittlement and are available in the strength/size required for high pressure and moderate temperature applications for sub-sea applications.

Domain Diagrams for the Sulfide Stress Cracking Resistance of High Strength Low Alloy steel 41xx Bar Stocks

Product Number: 51320-14590-SG

Author: Vipul Shinde, Manuel Marya

Publication Date: 2020

High-strength low-alloy steel bar stocks with 110ksi (758MPa) and 125ksi (862MPa) specified minimum yield strength (SMYS) are in demand for temporary and permanent downhole tools for sour service. NACE MR0175/ISO15156 currently allows the use of low-alloy steel bar stocks without any environmental restrictions up to 22HRC, which, by most specifications, corresponds to 80ksi (552MPa) SMYS. At higher SMYS, and with exclusions of API and proprietary sour tubular grades, NACE MR0175/ISO15156 does not address solid bar stocks, a gap and opportunity addressed by this investigation. Specifically, in this paper, the sulfide-stress cracking (SSC) of commercial UNS G41xxx (41xx) alloys, including 41xxMod (i.e., carefully selected or mill modified) is investigated following a series of NACE TM0177 Method A tests in either Solution B or A (NACE Region 3). Domain diagrams for 41xx alloys are disclosed, all demonstrating that 41xx solid bar stocks are SSC resistant above 150°F (66°C) when under a new and improved specification. When SMYS is raised to 125ksi (862MPa) with 34HRC max, a safe minimum temperature of 175°F (79.5°C) is confirmed for hollow bars, well in line with current NACE MR0175/ISO15156. The metallurgical and hardness requirements of 41xx alloys are also briefly discussed, along with opportunities for further modifications of 41xx bar stocks.

High Strength Austenite For Additive Manufacturing

Product Number: 51322-17496-SG

Author: Dr. Andreas Mohr, Dr. Horst Hill, Dipl.-Ing. Karlheinz P.J. Hoeren, M.sc. Janosch Conrads

Publication Date: 2022

$20.00

Typical austenitic stainless steels like 316L (S31603) contain chromium, nickel, and, optionally, molybdenum as major alloying elements. These are required to provide their beneficial properties, which include e.g. very high corrosion resistance and high ductility and toughness, yet showing comparably low strength and hardness. General corrosion resistance is primarily achieved by the element chromium, which causes formation of a thin but dense chromium oxide layer on the surface, when the amount of chromium dissolved in the metallic matrix is larger than approximately 10.5 wt%.

Very High Strength Low Alloy Steels For HPHT Applications

Product Number: 51322-17721-SG

Author: Florian Thebault, Julien Pennequin, John Fortaillier, Carine Landier

Publication Date: 2022

$20.00

More and more High Pressure High Temperature (HPHT) sour wells are operated worldwide. Challenging material selection is required for such severe operating conditions.^1,2 Very high strength materials, presenting yield strength above 896 MPa (130 ksi), are required for sustaining the pressure. Consequently, even a low amount of H₂S in the gas phase may lead to a H₂S partial pressure beyond the limit of 3.5 mbar (0.05 psi) established in NACE MR0175 / ISO 15156 standard.³ Indeed, both high yield strengths and partial pressures of H₂S contribute to a situation where the risk of Sulfide Stress Cracking (SSC) is high. The present paper is focusing on the SSC resistance of 130 ksi minimum yield strength material developed for covering such HPHT applications.
