Chromium-molybdenum cam khwb cia hlau yog dav siv nyob rau hauv kev lag luam teb nrog kuj zoo heev mechanical zog. Qhov sib ntxiv ntawm molybdenum rau chromium hlau tuaj yeem ua kom lub zog ntawmhlau castingstsis muaj qhov cuam tshuam loj rau qhov cuam tshuam toughness ntawm cam khwb cia hlau. Tsis tas li ntawd, chromium-molybdenum cam khwb cia hlau muaj qhov kub thiab txias kev ua haujlwm zoo heev. Tom qab quenching thiab tempering los yog normalizing kev kho cua sov, chromium-molybdenum cam khwb cia hlau tuaj yeem tau txais cov khoom zoo heev.
Molybdenum tuaj yeem txhim kho lub hardenability ntawm cam khwb cia hlau thiab txo cov temper brittleness ntawm cam khwb cia hlau. Chromium-molybdenum cam khwb cia hlau yog siv rauloj-section castingsthiab steel castings uas yuav tsum tau sib sib zog nqus hardening.
