Siab Carbon Chromium Bearing Steelyog cov khoom siv kub kub rau kev tsim precision dov bearings. Feem ntau hu ua yooj yim li"Chrome hlau, "Nws nta cov ntsiab lus carbon ntawm ~ 1.00% thiab cov ntsiab lus chromium ntawm ~ 1.50%.
Peb tus chijip qib,GCr15 (AISI 52100 / 100Cr6), yog tsim los sivNqus Degassing (VD)thiab tswj cov txheej txheem refining nruj me ntsis kom txo qis tsis yog -metallic inclusions (oxides thiab sulfides). Qhov siab purity no ua kom cov hlau muaj qhov tshwj xeebHu rau kev qaug zog, tso cai rau cov bearings khiav mus rau tsheej lab ntawm cov kiv puag ncig yam tsis muaj kev cuam tshuam lossis tsis ua haujlwm. Peb muab cov khoom no rau hauv aSpheroidize Annealedmob, kom ntseeg tau zoo heev machinability rau tig thiab sib sau ua ntej heat kho.

Cov yam ntxwv tseem ceebthiab Qhov Zoo
- Superior Fatigue Resistance:Kev huv huv siab (oxygen Tsawg dua lossis sib npaug li 12 ppm) txo qis qhov tsis xws luag hauv microscopic, tiv thaiv kev qaug zog tawg los ntawm kev pib nyob rau hauv siab - kev sib hloov ceev.
- High Hardness & Wear Resistance:Tom qab quenching thiab qis -kub tempering, lub hardness ncav cuag60-64 HRC, muab kev tiv thaiv zoo heev rau kev puas tsuaj thiab deformation nto.
- Spheroidized Microstructure:Peb cov txheej txheem annealing ua tiav ib qho kev nplua zoo, kev faib tawm ntawm kheej kheej carbides. Qhov no yog qhov tseem ceeb rauzoo machinabilitythiab xyuas kom cov hlau tsis tawg thaum quenching.
- Dimensional Stability:Kev kho cua sov meej kom ntseeg tau tias cov kabmob muaj peev xwm tswj tau lawv cov kev ua haujlwm nruj rau ntau xyoo ntawm kev ua haujlwm.

FAQ
Q1: Qhov txawv ntawm 52100 thiab Stainless Bearing Steel (440C) yog dab tsi?
A1: 52100 (GCr15) yog cov pa roj carbon -chromium steel uas muaj kev qaug zog zoo dua lub neej thiab kev thauj khoom- nqa lub peev xwm tab sis tsis zoo corrosion kuj. Nws yuav tsum tau lubrication. 440C yog stainless hlau siv nyob rau hauv corrosive ib puag ncig (khoom noj khoom haus, kev kho mob, thiab marine) tab sis muaj ib tug me ntsis load peev xwm thiab yog kim dua.
Q2: "Spheroidize Annealing" yog dab tsi thiab vim li cas nws tseem ceeb?
A2: Spheroidize Annealing yog kev kho cua sov uas hloov cov carbides hauv cov hlau rau hauv cov duab kheej kheej. Qhov no ua rau cov hlau mos txaus los ua machined (tig los yog txias tsim) thiab xyuas kom nws hardens uniformly thaum lub sij hawm kawg quenching txheej txheem. Peb muab tag nrho cov kabmob steel hauv qhov xwm txheej no.
Q3: 52100 steel puas tuaj yeem welded?
A3: Tsis yog vim nws cov ntsiab lus carbon siab heev (~ 1.0%), 52100 steel muaj qhov tsis zoo weldability. Vuam yuav ua rau brittle cracking. Cov khoom yuav tsum tau sib sau ua ke siv cov khoom siv los yog cov nplaum, tsis yog vuam.
Q4: Koj puas muab "Peeled" lossis "Centerless Ground" tuav?
A4: Yog. Rau automated machining (CNC Swiss Lathes), peb pom zoo Peeled & Polished los yog Centerless Ground tuav. Cov no muaj txoj kab uas hla nruj (ISO h9 / h10) thiab tsis pub dawb los ntawm decarburization, tso cai rau kev ua haujlwm tam sim.
