18CrMnNi2MoA yog ibqis-carbon alloy carburizing steelengineered rausiab -load iav thiab kis tau tus mob Cheebtsam. Nws yog tsim los ua kom tiav anyuaj, hnav- tiv taus nto tom qab carburizing, thaum tuav atawv thiab cuam tshuam -resistant core.
Lub alloy muaj pes tsawg leeg muab:
Chromium (Cr):Txhim kho hardenability thiab hnav tsis kam
Manganese (Mn):txhim kho lub zog thiab toughness
Nickel (Ni):nce kev cuam tshuam tsis kam thiab qaug zog lub neej
Molybdenum (Molybdenum):txhim kho lub zog thiab tiv thaiv temper embrittlement
Piv nrog rau cov qauv carburizing steels xws li 20CrMnTi, qib no muaj:
tob duacase hardening qhov tob
Siab duaqaug zog kuj nyob rau hauv hnyav loads
Zoo duakev ua tau zoo hauv cov iav loj
Nws yog dav siv nyob rau hauvmining, cua zog, hnyav machinery, thiab automotive kis industries.
