Molybdenum(feem ntau hu ua "moly") muaj ntau yam tseem ceeb siv nyob rau hauv alloy thiab stainless hlau, alloy cam khwb cia hlau thiab super alloys. Molybdenum yog ib tug muaj zog hardenability tus neeg sawv cev thiab yog ib tug ntawm ntau yam tshav kub kho alloy hlau.
Nws retards softening ntawm siab kub thiab yog li ntawd siv nyob rau hauv boiler thiab siab hlab ntsha steels, raws li zoo raws li ob peb qib ntawm kev kub ceev thiab lwm yam cuab yeej steels. Molybdenum txhim kho corrosion kuj ntawm stainless hlau.
Hauv HSLA steels, nws tsim cov qauv acicular ferrite. Molybdenum yog lub hauv paus rau ntau yam ntawm cov dov dual theem steels siv nyob rau hauv kev siv tsheb.
Thaum molybdenum feem ntau yuav siv sib hloov nrog chromium thiab vanadium, nyob rau hauv ntau zaus cov khoom nws imparts yog tshwj xeeb.
Yog li ntawd, nws txoj kev siv tau nthuav dav heev nyob rau ntau xyoo dhau los, nrog rau kev thov feem ntau nthuav tawm cov khoom siv.
Molybdenum yog muab los ua ferromolybdenum. Ferromolybdenum muaj qhov tsawg kawg nkaus ntawm 60% Mo. Txog li 1% txhua tus silicon thiab tooj liab tuaj yeem muaj. Ua ib qho khoom kim heev thiab siv cov khoom sib txuas ntxiv, ferromolybdenum tau ntim rau hauv cov kaus poom los yog lub hnab kom tiv thaiv kev poob.
