Carburizing bearing hlauyog homqis- carbon alloy structural steel(feem ntau nrog 0.08-0.23% carbon) muaj cov ntsiab lus alloying xws li chromium, nickel, thiab molybdenum. Tom qab tau tsim los rau hauv cov kabmob, nws nkag mus rau acarburizing (los yog carbonitriding)Kev kho cua sov txheej txheem. Cov txheej txheem no diffuses carbon rau hauv txheej txheej, tsim ibnyuaj, hnav-cov ntaub ntawv sab nraudthaum tuav atawv, ductile puab core.
Qhov tseem ceeb sib txawv ntawm Ordinary (Los ntawm -Hardened) Bearing Steel
Ordinary bearing steel feem ntau yog hais txoghigh-carbon chromium bearing hlau(piv txwv li, GCr15 / 100Cr6 / SAE 52100), qib siv dav tshaj plaws. Lub ntsiab sib txawv yog raws li nram no:
| Yam | Carburizing Bearing hlau | Ordinary (Rau-Hardened) Bearing Steel | |
| Cov ntsiab lus carbon | Tsawg: 0.08-0.23% | Siab: ~ 0.95-1.10% | |
| Kev kho cua sov | Carburizing + quenching + tempering | Direct quenching + low-temperature tempering | |
| Hardness Profile | Case nyuaj: HRC 58–62Core tawv: HRC 25–45 | Ib yam nyuaj thoob plaws: HRC 61–65 | |
| Core Toughness | Zoo heev (tiv thaiv qhov cuam tshuam / poob siab) | Relatively brittle (tsawg cuam tshuam tsis kam) | |
| Hom Qib | G20CrMo, G20CrNiMo, 8620H, SNCM220 | GCr15, 100Cr6, SUJ2, SAE 52100 | |
| Cov ntawv thov tseem ceeb | Heavy-impact scenarios: railway, dov zeb, hnyav machinery, tsheb kis tau tus mob | Lub hom phiaj dav dav, siab ceev, hnyav-load bearings (xws li, sib sib zog nqus-groove pob bearings) |
Carburizing bearing steel yog tsim los rau kev ua haujlwm siab, kev poob siab-nrhiav kev siv, muab lub ntsej muag tawv rau hnav tsis kam thiab cov tub ntxhais tawv tawv rau kev cuam tshuam.
Ordinary bearing steel muab kev sib xws, ultra-siab hardness thoob plaws tag nrho cov hla ntu, zoo tagnrho rau lub hom phiaj dav dav, siab-precision, high-speed bearing daim ntaub ntawv uas cuam tshuam kev thauj khoom tsawg heev.
