Product and Company Advantages Overview
Forged 42CrMo Power Transmission Shaft yog ib qho tseem ceeb ntawm kev ua haujlwm hnyav - cov khoom siv tshuab ua haujlwm, ua lub luag haujlwm tseem ceeb hauv siab - lub zog kinetic zog xa mus rau hauv cov tshuab. Cov khoom no yog tsim los ntawm 42CrMo alloy structural steel - thoob ntiaj teb lees paub ultra- siab- lub zog steel muaj npe nrov rau nws qhov tshwj xeeb ua ke ntawm lub zog, toughness, thiab hardenability - xa cov xaim hluav taws xob txhim khu kev qha txawm nyob rau hauv cov ntawv thov kev lag luam tshaj plaws.
42CrMo yog cov khoom siv zoo tshaj plaws rau lub zog xa hluav taws xob, cov ncej tsav tsheb, cov ncej iav, thiab cov ncej tseem ceeb, thiab yog siv dav hauv kev tsim kho tshuab, hnyav- tsheb thauj mus los, cov khoom siv hluav taws xob, cov tshuab mining, thiab cov ntawv thov marine. Nws qhov sib npaug thoob ntiaj teb suav nrog AISI 4140/4142 (USA), DIN 42CrMo4 (Lub Tebchaws Yelemees), thiab SCM440 (Nyiv), ua rau nws yog cov khoom siv thoob ntiaj teb lees paub thiab ntseeg siab.
Peb lub tuam txhab muaj tshaj li kaum tsib xyoos ntawm kev paub tshwj xeeb hauv forging thiab machining ntawm 42CrMo alloy steel shafts, muab tus nqi - zoo, siab - cov kev daws teeb meem zoo rau ntau pua tus neeg siv khoom thoob ntiaj teb.
Khoom Khoom - Vim li cas 42CrMo?
Qhov kev ua tau zoo ntawm peb cov forged kis tau tus mob pib nrog cov khoom siv nws tus kheej . 42CrMo alloy structural steel muaj kev sib xyaw tshwj xeeb ntawm cov khoom uas ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob sib kis:
Tshuaj muaj pes tsawg leeg (GB/T 3077 Standard)
| Element | Cov ntsiab lus (%) |
| Cov pa roj carbon (C) | 0.38 – 0.45 |
| Silicon (Si) | 0.17 – 0.37 |
| Manganese (Mn) | 0.50 – 0.80 |
| Chromium (Cr) | 0.90 – 1.20 |
| Molybdenum (hli) | 0.15 – 0.25 |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.035 |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.035 |
|
Qhov sib ntxiv ntawm molybdenum (Mo) - kwv yees li 0.15%–0.25% - yog qhov sib txawv tseem ceeb uas teeb tsa 42CrMo sib nrug ntawm 40Cr thiab lwm cov hlau alloy. Molybdenum yog ib qho muaj zog carbide- tsim cov ntsiab lus uas ua kom muaj zog hardenability thiab zoo suppresses temper brittleness. Thaum 40Cr ua tiav cov roj-quenched tseem ceeb txoj kab uas hla ntawm 25–40mm, 42CrMo txuas qhov no mus rau 40–80mm los yog ntau dua, kom ntseeg tau tias txawm loj -section shafts ua tau zoo ib yam hardness thiab lub zog thoob plaws tus ntoo khaub lig{17}}section.

Key Performance Advantages
Superior Strength & Hardenability
Nrog lub zog tensile tshaj 1080 MPa thiab tawm lub zog siab tshaj 930 MPa, 42CrMo muab lub siab load- bearing peev xwm yuav tsum tau rau hnyav- lub luag hauj lwm fais fab kis shafts raug siab torque thiab dabtsi yog khoov loads. Qhov tshwj xeeb hardenability ua kom cov cuab yeej ua haujlwm zoo ib yam hla cov ntoo khaub lig loj - ntu, tshem tawm cov kev ua haujlwm tsis zoo uas txwv qis dua - cov ntaub ntawv qib zoo li 45 # steel hauv cov kab loj dua.
Zoo heev Toughness & Fatigue Resistance
Tom qab quenching thiab tempering (Q&T), 42CrMo nthuav tawm kev qaug zog siab thiab ua haujlwm zoo rau ntau yam kev cuam tshuam. Cov khoom siv qhia tias tsis muaj qhov kub hnyiab tseem ceeb thiab tuav tau zoo heev qis - qhov kub thiab txias cuam tshuam toughness. Qhov kev sib xyaw ua ke ntawm lub zog thiab lub zog yog qhov tseem ceeb rau kev sib kis ntawm cov ncej uas muaj kev sib tsoo, kev poob siab, thiab kev ntxhov siab rov qab los ntawm kev ua haujlwm hauv ntiaj teb tiag -.
High -Tsub Ua Haujlwm
42CrMo tuav lub zog nkag siab thiab ua kom muaj zog ntawm qhov kub siab, ua rau nws tsim nyog rau kev siv hluav taws xob xa hluav taws xob uas muaj kev sib txhuam cua sov thiab ambient kub muaj kev txhawj xeeb.
Sib piv nrog 40Cr
Cov khoom siv kho tshuab dav dav ntawm 42CrMo ua tau zoo dua li ntawm 40Cr. Thaum 40Cr yog tus nqi-kev xaiv zoo rau nruab nrab- ntu ntu cov khoom raws li cov khoom siv sib xyaw ua ke, 42CrMo yog "siab-kawg configuration" rau loj-section, huab- qhov xwm txheej tseem ceeb ntawm cov khoom tsis ua haujlwm tsis yog qhov kev xaiv.
