Term explanation: What is hydrogen corrosion? Hydrogen corrosion includes three modes: hydrogen bubbling, hydrogen embrittlement, and hydrogen erosion. Generally, it refers to various types of damage that occur in carbon steel equipment in hydrogen-containing environments, caused by the diffusion of atomic hydrogen into the metal as a result of environmental chemistry or the electrochemical reactions between the metal and its environment (including corrosion reactions); all such damages are collectively termed hydrogen corrosion. ====================================== 【Mechanical Area】Recruitment for moderators and technicians – applications and referrals are welcome. 【Valid indefinitely】If you’re interested, come ahead! http://bbs.hcbbs.com/thread-1568748-1-1.html
Hydrogen corrosion, or hydrogen attack, occurs when steel is exposed to a high-temperature, high-pressure hydrogen environment; hydrogen atoms react with unstable carbides on the surface of the equipment or within the steel itself to form methane, resulting in decarburization of the steel and permanent damage to its mechanical strength. The methane generated inside the steel cannot escape and accumulates there, creating high local pressures that lead to severe bulging and cracking.
It refers to the situation where steel is exposed to a high-temperature, high-pressure hydrogen environment; hydrogen atoms react with unstable carbides on the surface of the equipment or within the steel itself to produce methane, resulting in carbon loss from the steel and permanent damage to its mechanical strength. The methane generated inside the steel cannot escape and accumulates there, creating high local pressures that lead to severe bulging and cracking.

The methane generated inside the steel cannot escape and accumulates there, creating high local pressures that lead to severe bulging and cracking.
