Book Description
This report deals with the deleterious effects of hydrogen gas on steel at elevated temperatures and/or pressures. Hydrogen attack on steels is manifest as decarburization, intergranular fissuring, or blistering. These conditions result in lowered tensile strength, ductility, and impact strength. The reaction of hydrogen with iron carbide to form methane is probably the most important chemical reaction involved in the attack on steel by hydrogen. Attack of steel at elevated temperatures and pressures is limited or prevented by the following measures: (1) use of steel alloyed with strong carbide-forming elements, (2) use of liners of resistant alloy steels, and (3) substitution of resistant nonferrous alloys.

Book Description
The nucleation and growth of methane bubbles in the hydrogen attack of pressure vessel steel has been shown to obey models developed to describe the growth of bubbles limiting the creep ductility of metals. This has been done through studies of the effect of prior deformation on bubble nucleation as well as the effect of methane pressure (stress) and temperature on growth kinetics. A comprehensive model of the factors limiting growth has been developed. Its application to the hydrogen attack of a 2 1/4 Cr-1 Mo steel leads to several interesting predictions.

Book Description
As geologic environments associated with oil and gas production have become increasingly aggressive, aqueous corrosion at high temperatures in the presence of hydrogen sulfide (H2S) is more frequently encountered. The understanding of sour corrosion mechanisms is an important but still largely elusive target, especially at high temperatures. The purpose of this project is to explore the thermodynamics and kinetics of H2S corrosion at high temperature, and to develop a thermodynamic model to predict the corrosion product layer formation, as well as a mechanistic kinetic model to predict the corrosion rate of mild steel at high temperature in the presence of H2S.
