WebHydrogen 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 ... WebOct 4, 2024 · Iron plays an important role in producing hemoglobin, an essential metalloprotein that your body uses to transport oxygen in blood. When your iron levels are low, it becomes harder to transport oxygen to important cells, such as the cells that stimulate the growth of your nails and hair.
