Hydrogen concentration, stress corrosion

The method can be used for studies on hydrogen diffusion and trapping in metals, which, for example, are relevant within the field of hydrogen-related stress corrosion cracking. Critical hydrogen concentrations for various types of cracking can be assessed. [Pg.312]

Sulfate ions have reactions similar to those of chloride. They are corrosion-causative agents (similar to oxygen and hydrogen) of the various types of concentration cell corrosion. In addition, they also are depassivation agents and may greatly accelerate the risk of stress corrosion mechanisms. Saline corrosion pits resulting from high concentrations of chloride and sulfate salts also may be associated with low pH corrosion because hydrochloric acid and sulfuric acid can form within the pit, under deposits. [Pg.250]

Sodium hydroxide, even at low concentrations, will cause stress corrosion cracking in stainless steel when subjected to temperatures above 100°C. Caustic solutions are much better handled in alloys with high concentrations of nickel, such as Alloy 400 or Alloy 600. Alloy 400 has also found success in applications involving fluoride, hydrogen fluoride, and hydrofluoric c dP ... [Pg.1251]
