Txheej txheem cej luam
TIAB SA 2391yog tus qauv German uas qhia txog cov txheej txheem xa khoom rauseamless, precision steel raj. Cov hlab no yog tus cwj pwm los ntawm lawv qhov zoo ntawm qhov tseeb, du nto tiav, thiab lub zog siab. Lawv feem ntau yog txias- kos (thiab qee zaum txias- dov) kom ua tiav cov kev zam no.
Tus qauv muab faib ua ob qhov tseem ceeb:
DIN 2391 Ntu 1:Npog seamless, txias - kos precision steel raj.
DIN 2391 Ntu 2:Npog welded, txias - kos precision steel raj.
Thaum tus qauv npog ntau qib steel, nws yog qhov muaj npe nrov tshaj plaws nrogcarbon hlauqib.
Cov yam ntxwv tseem ceeb thiab cov yam ntxwv
High Dimensional Accuracy:Cov kav dej no muaj kev tiv thaiv nruj heev ntawm sab nraud (OD) thiab phab ntsa tuab. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas cov khoom yuav tsum tau ua kom haum ua ke yam tsis muaj kev siv tshuab ntxiv.
Zoo heev Surface Finish:Qhov txias- txheej txheem kos duab ua rau muaj kev sib tw heev, nplai -dawb nto, uas feem ntau txaus rau kev siv zaum kawg yam tsis tas yuav ua tiav ntxiv.
Siab zog:Qhov txias- txheej txheem ua hauj lwm (kos duab los yog dov) ua hauj lwm- hardens cov hlau, ua rau nws cov yield zog thiab tensile zog piv rau kub- cov hlab tiav.
Seamless Construction (Part 1):Seamless variant tsis muaj weld seam, ua rau nws muaj zog ib puag ncig nws ncig thiab zoo tagnrho rau kev siv siab -siab.
Common Steel Qib thiab tshuaj muaj pes tsawg leeg
DIN 2391 qhia ntau qib steel. Cov qib carbon steel feem ntau yog:
| Qib Steel | Khoom Naj Npawb (Werkstoffnummer) | Kev piav qhia | Standard sib npaug (Approx.) |
|---|---|---|---|
| St 35 | 1.0308 | Tsawg- carbon steel, zoo weldability thiab formability. | ASTM A513 Hom 1, EN 10305-1 E235 |
| St 52 | 1.0530 | Siab dua - lub zog carbon steel nrog ntau dua yield zog. | ASTM A519 Qib 1020/1026, EN 10305-1 E355 |
| C 35 | 1.0506 | Nruab nrab- carbon steel, tuaj yeem ua cua sov- kho kom muaj zog dua. | ASTM A 519 1035 |
| C 45 | 1.0507 | Nruab nrab - carbon steel, siab zog thiab hardness. | ASTM A 519 1045 |
Hom Tshuaj Chemical Composition (Piv txwv):
Tshooj 35:C max 0.17%, Mn max 0.70%, Si max 0.30%, P max 0.035%, S max 0.035%
Qhov 52:C max 0.22%, Mn max 1.60%, Si max 0.55%, P max 0.035%, S max 0.035%
Mechanical Properties
Cov khoom siv kho tshuab tau txhim kho tau zoo los ntawm qhov txias - txheej txheem ua haujlwm.
| Qib Steel | Yield Strength (Re) Min. (MPa) | Tensile zog (Rm) (MPa) | Elongation (A) Min. (%) |
|---|---|---|---|
| St 35 | 390 MPa ua | 490 - 690 MPa | 12% |
| St 52 | 490 MPa ua | 610 - 840 MPa | 10% |
Nco tseg: Cov txiaj ntsig tiag tuaj yeem sib txawv raws li cov txheej txheem tsim khoom tshwj xeeb thiab qhov ntev ntawm lub raj.
Tolerances (Qhov tseem ceeb)
DIN 2391 cov kav dej tau paub txog lawv cov kev ua siab ntev. Piv txwv li, rau qhov ntau thiab tsawg:
Sab nraud Diameter Tolerance:Feem ntau h8 lossis h9 (nruab heev).
Piv txwv li: Rau 50 hli OD raj, h8 kam rau ua0 / -0.046 hli.
Phab ntsa Thickness kam rau ua:Feem ntau nyob ib ncig ntawm ± 10% ntawm nominal phab ntsa thickness.
Daim ntawv thov
Vim lawv qhov tseeb thiab lub zog, DIN 2391 cov kav dej tau siv rau hauv ntau qhov kev lag luam:
Hydraulic thiab Pneumatic Systems:Rau lub tog raj kheej, pistons, thiab actuator vaj tse.
Automotive Kev Lag Luam:Shock absorber cylinders, roj txhaj tshuab, cov khoom siv kauj.
Mechanical Engineering:Precision shafts, linear motion systems, bearings vaj tse, tshuab guards.
General Precision Machinery:Txhua daim ntawv thov uas yuav tsum tau muaj qhov siab - zoo, npaj tau- los - siv lub raj nrog cov machining tsawg.
Sib npaug thiab Superseding Standards
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias ntau lub teb chaws German cov qauv (DIN) tau hloov los ntawm European Norm (EN) cov qauv kom sib haum xeeb thoob plaws Tebchaws Europe.
Tus neeg sawv cev ncaj qha rau DIN 2391-1 yog EN 10305-1.Cov qauv no, lub npe "Steel tubes for precision applications - Technical delivery conditions - Part 1: Seamless cold drawn tubes," hais txog tib yam khoom ntau yam.
Thaum xaj lossis qhia meej, koj tam sim no yuav pom cov ntawv xa musEN 10305-1 E235(sib npaug rau St 35) los yogEN 10305-1 E355(sib npaug rau St 52).
