Kev ua tau zoo & qhov zoo:
Zoo Weldability: Tiv thaiv kev tawg thiab ua kom muaj zog, tawv welds.
Corrosion Resistance: Molybdenum cov ntsiab lus muab kev tiv thaiv zoo dua rau cov xov xwm corrosive.
Toughness: Ua kom muaj kev cuam tshuam zoo, txawm tias qhov kub thiab txias.
Formability: Exhibits zoo ductility rau txiav, dabtsi yog khoov, thiab stamping.
Daim ntawv thov:
Boilers & Pressure Vessels: Chaw tsim khoom rau kev lag luam boilers, nuclear reactors, thiab siab - siab tanks.
Petroleum & Chemical Industry: Siv nyob rau hauv reactors, separators, heat exchangers, thiab cia rau liquefied petroleum gas (LPG).
Lub Hwj Chim Muaj Peev Xwm: Ua hauj lwm hauv cov chaw nres tsheb fais fab rau siab - cov kav dej siab, lub tshuab nqus tsev, thiab cov cua kub dissipation units.
Shipbuilding: Tsim nyog rau nkoj hulls thiab lwm yam marine lug.
Aerospace: Siv rau hauv qee qhov kev siv aerospace uas xav tau lub zog siab thiab kub ua haujlwm.
