The Use of Hydrogen in the Iron and Steel Industry

EAF - Electric Arc Furnace for steel making is a rapid growing technology competing with the BF/BOF. Major feedstock is scrap steel. The purity of existing scrap steel is declining and needs virgin iron added to dilute the tramp elements such as copper and zinc to improve final product quality. DRI – Direct Reduced Iron is one of the iron ...

Metallic hydrogen

Metallic hydrogen is a phase of hydrogen in which it behaves like an electrical conductor.This phase was predicted in 1935 on theoretical grounds by Eugene Wigner and Hillard Bell Huntington. At high pressure and temperatures, metallic hydrogen can exist as a partial liquid rather than a solid, and researchers think it might be present in large …

Hydrogen embrittlement

Hydrogen embrittlement ( HE ), also known as hydrogen-assisted cracking or hydrogen-induced cracking ( HIC ), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting ...
