Explain about the Hydrogen Embrittlement

As a result of the action of acids on high-tensile steels, liberation of hydrogen takes place. It penetrates into the steel surface and makes it brittle and fracture prone. Even small amounts of hydrogen can cause significant damage to the tensile strength of high-tensile steel wires. Use of high-alumina cement and blast furnace slag cement can cause hydrogen embrittlement in wires. In order to prevent it taking place, it is essential to properly protect steel from the action of acids. Protective coverings should be provided over the tendons for this puruose.
