Dab tsi txawv ntawm ASTM A204 qib b thiab en 10028 16 mo3 boiler hlau?
A204 qib bthiab16mo3yog ob qho tib si lub nkoj siab hlau thiab yog siv los ua cov rwj thiab cov hlab ntsha siab.
A204 qib B siab Lub Hlua Ntses Hlau Belong yog rau American Standard ASTM thiab tuaj yeem siv rau nruab nrab thiab qis-kub siab rau cov nkoj.
16MO3 siab rau lub raj Hlau Hlau yog rau European Cov Qauv EN10028 thiab muaj qhov kub ua tsis kam.
ASTM A204 qib bCov phaj steel tau zoo corrosion tsis kam thiab kev ua haujlwm vuam ua tau zoo, ua rau muaj qee qhov chaw nyob hauv ib puag ncig thiab ib puag ncig kom tawg thiab porosity thaum lub sij hawm vuam. ASTM A204 GRB Hlau Phaj tau siv dav hauv cov roj av, tshuaj lom neeg, tshwj xeeb yog cov khoom lag luam, tso tsheb hlau luam, cov tshuaj tso tsheb hlau luam, reactors thiab lwm yam khoom siv. A204 qib siab rau lub nkoj ua haujlwm hlau kuj tseem siv tau los tsim cov qauv txheej txheem xws li txuas hniav thiab vaj tse.
16mo3Hlau yog ib tug carbon steel phaj rau cov khoom lag luam European, thiab muaj peev xwm ua haujlwm tau zoo nyob rau hauv mo3} Cov khoom siv siab Reactors, Roj thiab Roj Pipelines, thiab lwm yam} mo3} mo3} mo3} mo3} mo} mo3} mo3}} mo} Heat} Heat} Heev} mechanical້ນ kuj muaj cov tshuaj zoo heev, aerospace, tsheb thiab lwm thaj chaw.

Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | ASTM A204 qib b | En 10028-2 16 mo3 |
|---|---|---|
| Lub zog tensile | 485 - 620 MPa | 450 - 600 MPA |
| Yield zog (min) | 275 MPa (rau thickness tsawg dua los yog sib npaug rau 50mm) | 290 MPa (rau thickness tsawg dua los yog sib npaug rau 16 hli) |
| Kev Cuam Tshuam | Tsis tau hais meej meej (sib txawv los ntawm kev kho cua sov) | Ntau dua los yog sib luag rau 27 j ntawm -20℃(Yuav tsum tau Charpy V-Nti Kuaj) |
| Cov Kev Pab Ntau Tshaj | ~ 550 degree | ~ 5 |
Hwj txwv
A204 qib b: Weldability yog ib nrab vim yog nws cov ntsiab lus cr. Preheating (150-250 degree) thiab kev kho cua sov tom qab weld (duab) feem ntau yuav tsum tiv thaiv kev tawg kom txias thiab ua rau muaj kev ntxhov siab.
16mo3: Zoo Weldability vim tias txo cov roj carbon thiab stricter tswj ntawm impurities (p, s). Preheard yog tseem pom zoo tab sis tej zaum yuav tsawg dua kev ua kom muaj zog, thiab pwhalt feem ntau yuav tsum tau rau cov ntu tuab.
Cov Kev Siv Raug Raug
A204 qib b: Siv rau hauv qhov kub-kub, corrosive ib puag ncig (piv txwv li cov nroj tsuag, thiab cov tshuaj tiv thaiv kub, thiab ua tsaug rau cr-mo corrosion tsis kam).
16mo3: Feem ntau siv nyob rau hauv European boiler lub tshuab (piv txwv, cov tshuab tsim hluav taws xob ua haujlwm ntawm kev nce qib siab thiab kev cuam tshuam nyuaj yog qhov tseem ceeb rau kev ntseeg tau ntev.
