Ferrum fusum est mixtura carbonis ferrea cum fractione massa carbonis maior quam 2.11%.Ferrum projice obtinetur per remotionem suillo ferro in fornace, ferroalloy addito, faece ferro, et rediens ad fornacem componendam.Ferrum glaucum fusum et ductile ferrum sunt duo ferrea in liminis late usitata.
Gradus ferrei Sinarum iactus maxime proprietatibus mechanicis exprimuntur et distinguuntur.Prima numerus graduum in gradu distrahens vim minimam indicat (in MPa), et secunda copia numerorum (si quis) minimam distantiam in luce (%) indicat.Binae numerorum uirgula separantur "-".
Codex litteratus Anglicus ex ferro glauco fusi est HT, ubi H prima littera Sinensium Pinyin (Hui Se) griseum significat;T littera prima Sinensi Pinyin (Tie) ferrea est.Numeri in gradibus ferreis griseo Sinarum vim distrahentes minimam indicant (MPa).Exempli gratia, HT250 significat ferrum cinereum fusile cum viribus 250 MPa minimum distrahentibus.
