Dab tsi yog cov khoom thiab kev siv ntawmferromolybdenum?
Lub atomic luj ntawm molybdenum nyob rau hauv ferromolybdenum yog 95.94, lub sab nrauv hluav taws xob qauv yog 4d5s, lub melting point yog 2615 degrees, lub boiling point yog 461 0 degrees, thiab qhov ceev (20) yog 10.2g / cm2. Muaj ferromolybdenum muaj li 60% molybdenum, muaj ib tug melting point ntawm 1800 ~ 1900 degree, thiab ib tug ceev ntawm txog 9.0g / cm2.
Kev ua haujlwm ntawm molybdenum hlau tuaj yeem ua tiav raws li kev txhim kho hardenability, thiab thermal zog, tiv thaiv temper brittleness, txhim kho remanence thiab coercive quab yuam, corrosion kuj nyob rau hauv tej yam xov xwm, thiab tiv thaiv pitting corrosion tendencies.
Ferromolybdenum tau siv dav hauv ntau hom hlau xws li cov qauv hlau, lub caij nplooj ntoos hlav steel, cov kabmob hlau, cov cuab yeej steel, stainless acid-resistant steel, steel-resistant steel (tseem hu ua cov hlau tsis muaj cua sov), thiab hlau nplaum. Vim tias nws muaj ntau qhov txiaj ntsig zoo ntawm cov hlau, molybdenum hauv cam khwb cia hlau muaj txiaj ntsig zoo hauv kev ua kom muaj zog thiab tawv.
Thaum tus nqi ntxiv yog 0.25% ~ 1.25%, cov qauv pearlite matrix kuj tuaj yeem tsim rau nruab nrab thiab loj hla ntu castings, uas feem ntau yog siv los hnav-resistant castings xws li yob.
