It is not to be confused with hydrogen embrittlement or other forms of low temperature hydrogen damage. HTHA is the result of hydrogen dissociating and dissolving in the steel, and then reacting with the carbon in solution in the steel to form methane. This causes the fissures and cracking which are typical of HTHA. Surface decarburisation results in a decrease in hardness and increase in ductility of the material near the surface.
Molybdenum is a chemical element with the symbol Mo and atomic number The metal was first isolated in by Peter Jacob Hjelm. Molybdenum does not occur naturally as a free metal on Earth; it is found only in various oxidation states in minerals. The free element, a silvery metal with a gray cast, has the sixth-highest melting point of any element. Molybdenum-bearing enzymes are by far the most common bacterial catalysts for breaking the chemical bond in atmospheric molecular nitrogen in the process of biological nitrogen fixation.
