Abstract :Steel is an alloy of iron and carbon and various other elements including chromium, nickel, manganese, vanadium,
titanium, cobalt and tungsten. Steel is known for its high tensile and high fatigue strength and is employed hugely in
buildings, weapons, and tool and automobile applications. In modern era, the production and consumption of steel
has become a measure of a Nations economic strength. Therefore the maintenance of steel and prevention from
corrosion is a matter of worldwide concern. The chief corrosion method of steel is hydrogen embrittlement. Various
experimental researches and theoretical investigations have been carried out to study about the mechanism of
hydrogen embrittlement in industrial steels and its prevention.
