Cov khoom siv ntau tshaj plaws rau cov kabmob rau cov kabmob steel yog siv. Cov khoom siv feem ntau siv hauv cov kabmob steel yog: carburizing bearing steel(G20CR2NI4A)thiab high-carbon chromium bearing steel(GCR15/GCR15SMN/GCR18M0). Raws li kev nkag siab tshwj xeeb, qhov kev ua tau zoo ntawm ob cov khoom siv steel yog sib koom. Kuv vam tias txhua tus tuaj yeem paub txog thaum yuav cov khoom siv bearing thiab yuav cov kabmob uas haum tshaj plaws.
Carburizing hlau (G20CR2NI4A)
G20CR2NI4A bearing steel is a high -quality alloy carburizing steel (low carbon C: 0.17 ~ 0.23) for carburizing steel for manufacturing bearing parts. The bearing parts made with such steels are used to produce heat treatment by carburizing, raising fire, and fire. After the process, the surface has high hardness (hardness> HRC60) and a certain abrasion resistance and high resistance to contact fatigue. Low carbon C: 0.17 ~ 0.23 ensures that the heart has good toughness (hardness>HRC33 -48). Qhov saum npoo no muaj cov yam ntxwv ntawm toughness, uas ua rau cov carburizing bearing steel ua haujlwm ruaj khov nyob rau hauv cov xwm txheej uas muaj kev cuam tshuam loj. Nyob rau hauv luv luv, qhov zoo ntawm carburizing steel bearings yog:
1. Qhov saum npoo ntawm qhov chaw yog khaws cia tom qab carburizing thiab quenching, thiab lub zog tiv thaiv kev qaug zog yog qhov zoo.
2. Nws muaj peev xwm cuam tshuam lub peev xwm, thiab txheej txheej sclerosis muaj qhov tawg me ntsis thiab nws tsis yooj yim los nthuav sab hauv. Qhov saum npoo muaj siab hardness thiab lub plawv tsis tshua muaj zog (feem ntau 35HRC ~ 40HRC). Piv nrog rau high-carbon chromium bearing steel, nws muaj lub plawv zoo toughness.
3. Qhov tob thiab concentration ntawm carburizing tuaj yeem hloov kho raws li qhov xav tau.
4. Kev txwv ntawm qhov loj thiab tuab ntawm cov kabmob.
High-carbon chromium bearing hlau(GCR15/GCR15SMN/GCR18M0)
High-carbon chromium bearing steel yog high-carbon alloy steel uas muaj 1.30 ~ 1.65 feem pua ntawm chromium, uas yog tus cwj pwm los ntawm: micro-cov ntaub so ntswg tom qab kev kho cua sov yog qhov sib xws thiab ruaj khov, siab thiab tsis sib xws hauv hardness, zoo hnav tsis kam, siab sib cuag. qaug zog, zoo, zoo, zoo Size stability thiab corrosion kuj. Tom qab lub ballistic annealing, nws cov kev ua tau zoo yog zoo. Cov hlau no tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov kabmob ntawm cov kabmob khiav hauv cov xwm txheej dav dav.
1. High-carbon chromium bearing steel yog dav siv thoob plaws ntiaj teb. Feem ntau siv daim npav yogGCR15thiabGCR15Simn. Hauv kuv lub tebchaws, nws suav txog li 80 feem pua ntawm tag nrho cov kabmob steel. Lub quenchtability yog zoo duaGCR15steel, yog li rau qhov loj-qhov loj qhov bearings, GCR15Simn steel yuav tsum tau siv.
2. GCR15 bearing steel yog siv los ua cav bearing, tshuab cuab yeej, motors, thiab lwm yam siv los ntawm tsheb, tsheb laij teb, tso tsheb hlau luam, aircraft, thiab lwm yam., raws li zoo raws li railway tsheb, mining machinery, universal mechanical bearings.
3. GCR15SIMN bearing steel yog tsuas yog siv los ua cov kabmob loj nrog cov phab ntsa loj, xws li ntau yam loj thiab cov kabmob loj ntxiv, uas feem ntau yog siv rau hauv kev ua haujlwm tsis muaj kev cuam tshuam loj ntawm cov cuab yeej siv tshuab hnyav thiab cov tshuab dov.
4. Vim hais tias cov kab nrib pleb ntawm GCR15SIMN steel yog ntau rhiab heev thiab muaj kev poob siab tsis zoo, cov phab ntsa tuab nrog cov kev cuam tshuam tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev siv. Nyob rau hauv cov xwm txheej ntawm kev cuam tshuam loj, GCR15Simn steel tseem txwv tsis pub siv nyob rau hauv cov xwm txheej ntawm kev cuam tshuam loj.GCR18MOtau tsim kho tam sim noGCR18MOhigh-quenching steel thiab abrasion tsis kam. Nws qhov kev ua tau zoo yog qhov zoo tshaj rau GCR15SIMN steel, thiab tuaj yeem hloov GCR15Simn steel ntawm kev tsheb nqaj hlau bearings, dov tshuab bearing, thiab mining mechanical bearings.
