15CrNi4MoA yog aqis-carbon alloy carburizing steeldav siv nyob rau hauvsiab -load gears thiab shafts. Nws yog tsim los ua kom tiav anyuaj, hnav-resistant ntotom qab carburizing thaum tuav atawv, ductile core, ua rau nws zoo tagnrho rauhnyav-cov khoom siv kis tau tus mob.
Cov ntsiab lus tseem ceeb ntawm alloying:
Chromium (Cr):txhim kho hardenability thiab hnav tsis kam
Nickel (Ni):txhim kho toughness thiab cuam tshuam tsis kam
Molybdenum (Molybdenum):nce lub zog thiab txo cov temper embrittlement
Piv rau cov pa carburizing steels zoo li 20CrMnTi:
tob duacarburized case qhov tob
Zoo duaqaug zog kuj nyob rau hauv hnyav load
Txhim khocuam tshuam kev ua tau zoo rau cov iav loj
Cov ntawv thov suav nrogautomotive kis tau tus mob, hnyav machinery, thiab industrial gear systems.
