Corrosion-Induced Hydrogen Entry to Steel and a Risk of Hydrogen Embrittlement

Product Number: 51323-19560-SG

Hydrogen embrittlement is a process that results in a decrease of the ductility of metals as a result of absorbed hydrogen. Advanced high-strength steels used in the automotive industry are materials that are considered prone to hydrogen embrittlement. Hydrogen can enter the material during steelmaking or processing steps, such as pickling, cleaning, phosphating, and electroplating.

Effect of H2S Fugacity on Hydrogen Uptake in Carbon Steels for Upstream Applications

Product Number: 51324-20951-SG

The presence of dissolved hydrogen sulfide in upstream or refining fluids is known to encourage hydrogen-induced mechanical failures of carbon or low alloy steel. Historically, the solution pH and the gaseous partial pressure of H2S (PH2S, bar) are used to evaluate an aqueous environment’s severity during materials corrosion cracking qualification. However, in recent years, it is suggested that the H2S fugacity (fH2S, an effective H2S partial pressure in bar) and actual dissolved H2S concentration ([H2S]aq) be used, rather than the PH2S, to better account for the effect of total pressure on steel corrosion cracking performance. In this paper, results obtained in a Joint Industry Programme (JIP) focused on evaluating the effect of fH2S on the hydrogen permeation across upstream steels using hydrogen pressure probe sensors and electrochemical Devanathan-Stachurski permeation tests are presented. A positive correlation between H-permeation rate at steady-state and environment fH2S or [H2Saq] is measured for numerous carbon steel grades in acetate-buffered 5% NaCl solution at pH ~ 4 and PH2S (~1bar), tested at total pressure between 1 – 300 bar. Furthermore, hydrogen induced cracking of a susceptible carbon steel grade increases when evaluated as a function of increasing fH2S for the same PH2S/pH combination.

Evaluation of Susceptibility of an API 5L X-52 Pipeline Steel to Hydrogen Stress Cracking and Ethanol Stress Corrosion Cracking in Bio-Based Fuel Grade Ethanol Feedstocks

Product Number: 51323-18794-SG

Author: Jie He, Brent Sherar, Peter Ellis II, Russ Kane

Publication Date: 2023

$20.00

Over the past two decades, bio-based fuel-grade ethanols (BFGEs), derived from a variety of agriculture feedstocks (e.g., corn, sugar cane, soybean oil, and sugar beet), are increasingly being used as a renewable energy source to reduce the dependence of fossil fuels for motor vehicle applications. One cost-effective and environmentally benign way to transport BFGEs is through steel transmission pipelines. However, cases of environmentally assisted cracking (EAC) in the transportation of BFGEs have been documented including some in pipelines.

With the increasing global energy demand, the transportation volume of natural gas increases rapidly, and pipeline transportation has become the most commonly used transportation mode of natural gas. Hydrogen is produced as a byproduct of ethylene production from ethane. Hydrogen is flammable and explosive. If it is directly discharged into the atmosphere, there are some safety risks. As a kind of efficient and clean secondary energy, hydrogen can not only avoid energy waste, but also increase economic benefit if it is mixed into natural gas pipeline.
