45CrNiMoV (Q45CrNiMoV) is asiab-lub zog qis- alloy structural steelntxiv dag zog nrognickel (Ni), chromium (Cr), molybdenum (Mo), thiab vanadium (V). Nws yog engineered rauCov khoom tseem ceeb ua haujlwm nyob rau hauv kev ntxhov siab, cuam tshuam kev thauj khoom, thiab kev qaug zog.
Piv nrog cov tsoos alloy steels, qib no muaj:
Siab zog thiab toughness sib npaug
Txhim kho kev qaug zog
Txhim kho hardenability rau cov ntoo khaub lig loj -sections
Zoo dua tsis kam mus rau temper embrittlement
Vim cov khoom no, 45CrNiMoV tau siv dav hauvaerospace, zog, khoom hnyav, thiab siab -kawg kev lag luam.
