30CrNi4MoA (EN30B) yog aqis-carbon Ni-Cr-Mo alloy carburizing steeltsim rauhnyav- lub luag haujlwm gears, ncej, thiab kis tau tus mob. Nws tsim ibnyuaj, hnav-resistant ntothaum tuav atawv, ductile core, kom ntseeg tauntev - kev cia siab rau lub sij hawm nyob rau hauv siab load thiab cyclic stress.
Cov ntsiab lus tseem ceeb Alloying:
Chromium (Cr):nce hardenability thiab nto hnav tsis kam
Nickel (Ni):txhim kho toughness thiab cuam tshuam tsis kam
Molybdenum (Molybdenum):txhim khu lub zog thiab txo cov temper embrittlement
Piv nrog 20CrMnTi thiab lwm yam carburizing steels:
Ua tiavsib sib zog nqus cov ntaub ntawv hardening
Muabsiab zog kuj thiab toughness
Ua kev ntseeg siab hauvloj - txoj kab uas hla gears thiab hnyav ncej
Cov ntawv thov feem ntau suav nrogautomotive kis systems, industrial machinery, thiab hnyav - lub luag haujlwm gearboxes.
