TS EN 10297-1 Seamless Alloy Tubes rau kev tsim kho tshuab
TS EN 10297-1yog European tus qauv tswj hwmseamless ncig raj ntawm non{0}}alloy thiab alloy steelsrau mechanical thiab general engineering. Tsis zoo li lub siab- cov qauv nkoj, EN 10297-1 yog sau rau cov khoom uas nqa cov khoom hnyav zoo li qub thiab dynamic loads - tsav shafts, axles, crane booms, telescopic cylinders thiab fais fab - kis tau tus mob - qhov twg lub raj feem ntau machined ib feem ua tiav.
Thawj Tswj Hwm Alloy Qib
| Qib | Khoom No. | Hom kev siv |
|---|---|---|
| 30 CrMo4 | 1.7218 | Automotive steering qhov chaw, lub teeb iav ncej, siab -toughness Cheebtsam |
| 42CrMo4 | 1.7225 | Heavy machinery qag, siab - lub zog ncej (European sib npaug ntawm AISI 4140) |
| 34 CrNiMo6 | 1.6582 | Heev heev -cov khoom ua haujlwm yuav tsum tau ductility ntawm siab hardness |
| 34 CrMo4 | 1.7220 | General engineering qhov yuav tsum tau sib sib zog nqus hardenability |
Mechanical Properties (Quenched thiab Tempered)
| Qib | Khoom No. | Tensile zog min. (+ QT) | Yield zog min. (+ QT) |
|---|---|---|---|
| 30 CrMo4 | 1.7218 | 800 MPa | 550 MPa |
| 42CrMo4 | 1.7225 | 900-1100 MPa | 650 MPa |
| 34 CrMo4 | 1.7220 | 850-1050 MPa | 600 MPa |
Tubes feem ntau muab nkag rau hauvnormalized (+ N)los yogquenched thiab tempered (+ QT)mob. Cov xwm txheej +QT ua rau tempered martensite, xa cov toughness siab tshaj plaws - mus rau - lub zog piv thiab cov lus teb kwv yees rau tom qab machining thiab hauv zos hardening.
Manufacturing Advantages ntawm Seamless Tsim
TS EN 10297-1 Cov hlab ntsha tshwj xeeb yog seamless, tsim los ntawm kev tho kub thiab dov ntawm cov khoom sib dhos. Qhov no yields ahomogeneous microstructureuas tsis muaj weld- seam irregularities - ib tug txiav txim kom zoo dua rau rotating los yog heev stressed qhov chaw, qhov twg metallurgical tsis muaj zog taw tes los yog loj imbalance yuav pib qaug zog tsis ua hauj lwm. Cov txheej txheem seamless tseem muab cov phab ntsa tuab, uas ua rau cov khoom sib npaug sib npaug thiab kwv yees tau nyob rau hauv tshav kub- kho cov lus teb.

Vuam thiab Fabrication Guide
Alloy qib xws li 42CrMo4 yog weldable tab sis yuav tsum tau tswj: preheating rau200-300 degreethiab yuav tsum tau tshaj tawm -weld heat treatment (PWHT) kom tiv thaiv kom txhob txias tawg nyob rau hauv siab -hardenability tshav kub- cuam tshuam cheeb tsam. Qhov siab tshaj plaws qhov ntev thiab kev huv huv yog xav tau rau cov kab hydraulic, EN 10305-1 precision raj yog nyiam dua EN 10297-1.
Cov lus nug nquag nug (FAQ)
Puas yog EN 10297-1 haum rau cov hydraulics siab?
Cov khoom siv muaj zog txaus, tab sis rau kev pabcuam hydraulic kab EN 10305-1 feem ntau yog nyiam rau nws qhov nruj dua qhov ntev thiab kev ua kom huv si.
42CrMo4 raj puas tuaj yeem welded?
Yog lawm, nrog preheat ntawm 200-300℃thiab yuav tsum tau tshaj tawm -weld kho cua sov kom tsis txhob txias tawg nyob rau hauv lub hardenable tshav kub- cuam tshuam cheeb tsam.
Qhov siab tshaj plaws ua haujlwm kub yog dab tsi?
Rau cov qauv kev pabcuam cov alloys feem ntau txwv rau txog 400 degree; rau boiler thiab cua sov- rov ua haujlwm, EN 10216-2 qib siab yuav tsum tau ua.
Tus mob + QT ua haujlwm li cas?
quenching thiab tempering refines tus qauv rau tempered martensite, maximizing lub toughness - rau - zog piv thiab muab kwv yees los ntawm - hardness.
Puas muaj cov seem square lossis rectangular?
Tsis muaj - EN 10297-1 suav nrog cov kab hla hla nkaus xwb. Rau cov qauv hollow seem, saib EN 10210 (kub tiav) lossis EN 10219 (txias tsim).
Qhov loj me yog dab tsi?
Seamless raj nyob rau hauv EN 10297-1 yog tsim nyob rau hauv ntau yam, feem ntau ntawm li 20 hli mus rau tshaj 500 hli OD nyob ntawm txoj kev zeb.
