ASTM A209 GR. T1 Alloy Steel Seamless Tubes
Nov 05, 2025
A209T1 Cov Yeeb Nkab HlauFeem ntau yog raws li cov pa roj carbon hlau, feem ntau muaj cov qauv me me los txhim kho nws cov khoom siv neeg. Nws muaj qhov ntsuas tensile thiab cov txiaj ntsig lub zog, ua kom muaj kev tsim nyog. Piv rau lwm hom cov kav hlau, A209T1 ua tau zoo hauv vuam thiab txias bending cov txheej txheem, nrog tsawg kev pheej hmoo ntawm kev tawg lossis deformation. Nws txoj kev kho mob saum npoo muaj qee cov kev kho corrosion, ua rau nws haum rau ntev- siv nyob rau hauv ib puag ncig ib puag ncig.
A209T1 Alloy Yeeb Nkab (ASME SA-209 Txuj Ci)Yog aCarbon - molybdenum alloy seamless steel yeeb nkabNrog rau cov tshuaj lom neeg hauv qab no:
Molybdenum (mo, 0.44% -0.65%): Lub caij tseem ceeb uas txhim kho siab siab - kub creep tsis kam, nrog lub zog tensile ntawmNtau dua los yog sib npaug rau 515 MPa ntawm 510 degree.
Cov pa roj carbon (C, 0.15% -0.25%)ThiabManganese (MN, 0.30% -0.80%): Ua haujlwm Synergistically kom nce cov khoom siv zog, ua tiav aChav - kub tensile lub zog ntawm 630 mpa.
Silicon (Si, 0.10% -0.50%): Ua ib qho anti {- oxidation tiv thaiv txheej, txo qhov corrosion tus nqi hauv high- dej sov.
Tsawg sulfur thiab phosphorus (s / p tsawg dua lossis sib npaug rau 0.025%): Tswj los ntawm Nqus Degassing Reining kom ntseeg tau cov khoom siv huv.
Qhov Zoo
High - kub ruaj khov
Ntev - Term Service ntawm510 degree, Nrognkag los tiv thaiv 3 zaug siab duaDua li cov pa roj carbon hlau, ntsib cov cai ntawm590 DEGREE /31.2 MPANyob rau hauv lub hwj huam cog boiler superheaters.
Tswj hwm cov qauv txheej txheem rauLuv - kev ua haujlwm ntawm 800 degree, Nrog aThermal nthuav tawm coefficievei tsawg dua lossis sib npaug rau 12.6 × 10⁻⁶ / degree.
Corrosion Kuj
Tsis muaj xeb tom qab 2000 teev nyob rau hauv 3.5% nacl ntsev tsuag tsuag.
Lub cev txhua xyoo tsawg dua los yog sib npaug rau 0.03 hliNyob rau hauv cov sulfide ib puag ncig.
Zoo tshajhigh - kub oxidation tsis kam, Nrog ibOxidation tus nqi tsawg dua los yog sib npaug rau 0.05 mm / xyoo ntawm 850 degree.
Cov txheej txheem hloov tau
Txhawb nqaflame cutting (for wall thickness >30 hli)ThiabLaser Txiav (Precision ± 0.1 hli), Nrog aTxiav saum npoo roughness ra tsawg dua los yog sib npaug rau 1.6 μm.
Vuam siv TIG txheej txheem (ER80s cov tub lim hlau), NrogTsis muaj tshaj tawm - Weld Kev Kho Tshav Kub Yuav Tsum TauThiabWeld lub zog ncav cuag 95% ntawm lub hauv paus hlau.
Cov ntaub ntawv no zoo tagnrho rausiab - kub thiab siab -} qhov kev siv siabNyob rau hauv cov fais fab nroj tsuag, petrochemicals, thiab lwm cov chaw xav tau kev lag luam.
