1. Tus lej: 1.8935
Nov yog aWerkstoffnumummer(Cov ntaub ntawv tus lej) los ntawm German Din thiab European en qauv.
1.8935sib raug rau cov qib steel25Cro4.
Nws yog qhov qis -} alloy, cua sov - Cov hlau kho tau zoo thiab lub zog zoo.
2. Cov khoom siv muaj pes tsawg leeg thiab cov khoom (25CRRO4 / 1.8935)
Lub npe "25crmo4" tawg cia nws kwv yees li kwv yees tshuaj tivthaiv:
25: ~ 0.25% carbon -}}} Nrhiav lub zog thiab cov neeg ua haujlwm tsis txaus ntseeg.
Cr: ~ 1% chromium - muaj ntau zog, txhim kho corrosion tsis kam, thiab tswj lub zog ntawm qhov kub.
Mo: ~ 0.2% molybdenum - txhim kho lub zog ntawm kev kub siab, txhim kho kev pheej hmoo, thiab txo qhov kev pheej hmoo ntawm embrittlementlement.
Cov yam ntxwv tseem ceeb:
Lub zog siab - rau - qhov hnyav} qhov hnyav. Piv
Zoo toughness thiab ductility
Foob zoo heev
Zoo Weldability(Nrog rau pre -- cua sov thiab tshaj tawm - weld kev kho cua sov)
Lub tshuab zoo
Cov cuab yeej siv tau ruaj khov kho ntawm kev nce siab kub(Txog rau kwv yees li . 500-550 degree)
3. "Seamless" txheej txheem tsim khoom (sms)
Lub yeeb nkab uas tsis muaj tseeb yas yog tsim los ntawm tho qhov khoom siv cov khoom siv hollow yam tsis muaj nqaws lossis Welds.
Qhov zoo ntawm cov kav dej seamless:
Lub zog hnav zoo li:Tsis muaj cov ntsiab lus tsis muaj zog los ntawm kev sib tshuam weld.
Zoo dua rau kev kub siab:Withstands siab dua sab hauv thiab sab nraud pressures.
Zoo li phab ntsa tuab:Ntau txhim khu kev qha rau cov ntawv thov tseem ceeb.
Superior ovality thiab eccentricity:Feem ntau cov khaub ncaws tsis zoo tshaj plaws.
4. Cov Ntawv Thov Tib Neeg
Vim nws ua ke ntawm lub zog, kev ua kom muaj zog, thiab kub kuj, 1.8935 seamless kav yog siv nyob rau hauv cov ntawv thov xav xws li:
Lub zog tiam:Tuber boiles, lub leeg supertheat, thiab siab-} qhov siab cov kab hauv cov nroj tsuag fais fab.
Roj & Roj Kev Lag Luam:Downhole tubing, casing, thiab cov khoom siv hauv kev ua kom huv thiab cov nroj tsuag petrochemical.
Automotive thiab Aerospace:High - Kev siv kev ntxhov siab cov txheej txheem, cov kab hydraulic, thiab tsav cov phuam.
Neeg Kho Tshuab Engineering:Hydraulic Thooj Voos Kheej Kheej, Piston Rods, thiab lwm qhov siab - lub zog tshuab qhov chaw.
Siab Hlab:Rau khaws cov roj thiab cov kua hauv qab kev kub siab.
5. Cov qhab nia sib npaug hauv lwm cov qauv
Cov hlau no tau lees paub thoob ntiaj teb nyob rau hauv cov rooj sib tham uas sib txawv:
| Lub hom phiaj | Xws li qib |
|---|---|
| Din / en | 1.8935, 25CRMO4 |
| ASTM | A519 (rau lub raj), zoo ib yam li 4130 (txawm tias 4130 muaj me ntsis sib txawv CR / MO Ratios) |
| Tsis yog | G41300 |
| JIS | SCM425 |
Lub ntsiab
A 1.8935 Seamless steel yeeb nkabyog ahigh - kev ua tau, chromium - molybdenum alloy steel rajtsim kom tsis muaj ib leeg. Nws yog xaiv rau cov ntawv thov uas ntseeg tau, muaj zog, siab tsis kam, thiab ua haujlwm nyob rau hauv kev ntxhov siab lossis kub kub yog qhov tseem ceeb.
Thaum sourcing cov khoom no, nws yog qhov tseem ceeb los qhia ob yam khoom (1.8935 / piv txwv li cov qauv tseem ceeb (EN, EN 1091) kom ntseeg tau tias koj tau txais cov khoom raug.
