Cais
Defnyddir bariau molybdenwm yn bennaf yn y diwydiant dur, i wneud gwell dur di-staen. Gall molybdenwm fel elfen aloi o ddur gynyddu cryfder dur, caiff ei ychwanegu at ddur di-staen i gynyddu ymwrthedd cyrydiad. Mae tua 10 y cant o gynhyrchiad dur di-staen yn cynnwys molybdenwm, ac mae'r cynnwys tua 2 y cant ar gyfartaledd. Yn draddodiadol, y dur di-staen gradd moly pwysicaf yw'r math austenitig 316 (18% Cr, 10% Ni a 2 neu 2.5% Mo), sy'n cynrychioli tua 7 y cant o gynhyrchu dur di-staen byd-eang.
