Tab sis dab tsi raws nraim muab nws nws cov khoom zoo tshaj?
Cia peb ua kom tawg nws cov tshuaj muaj pes tsawg leeg tshuaj thiab yog vim li cas cov teeb meem rau cov engineers, cov neeg tsim qauv, thiab cov kws tshaj lij tshwj xeeb.
Dab tsi yog en 10028-2 16 mo3 steel?
16mo3 yog molybdenum -} alloyed steel phaj teev nyob rau hauv European cov qauv en 10028-2. Nws yog tshwj xeeb tsim rau welded siab cov hlab ntsha, boilers, thiab lwm yam khoom siv uas yuav tsum ua haujlwm nyob rau hauv siab kub thiab txhawb nqa qhov kub.
Tshuaj lom neeg muaj pes tsawg leeg ntawm 16mo3
Cov lus zais rau 16mo3 kev ua tau zoo nyob hauv nws cov mis tawv ncauj. Ntawm no yog cov ncauj lus kom ntxaws ntawm nws cov pes tsawg leeg los ntawm qhov hnyav (%):
| Lub ntsiab | Cov ntsiab lus (%) | Tseem ceeb tsheej |
|---|---|---|
| Carbon (c) | 0.12 - 0.20 | Muab lub zog muaj zog thiab hardness. |
| Manganese (MN) | 0.40 - 1.00 | Txhim kho lub zog thiab cov tawv nqaij tawv. |
| Silicon (si) | Tsawg dua los yog sib npaug rau 0.35 | Ua rau deoxidizer thaum lub sij hawm statmaking statmaking. |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.025 | Impurity; khaws cia tsawg los khaws cov tawv tawv. |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.010 | Impurity; pheej nyob tsis tshua muaj kev txhim kho weldability. |
| Molybdenum (mo) | 0.25 - 0.35 | Neeg uas ua ntawv lub hnub qub. Confers high - kub lub zog thiab cov plaw ua haujlwm. |
| Chromium (cr) | Tsawg dua los yog sib npaug rau 0.30 | Muab cov oxidation me oxidation tiv taus. |
| Aluminium (AL) | Ntau dua los yog sib npaug rau 0.020 (ah) | Grain confiner rau kev txhim kho kev txhim kho. |
Vim li cas Molybdenum (mo) yog cov khoom tseem ceeb
Kev tsim qauv "16mo3" cov lus qhia ntawm nws tus tub ntxhais tus kheej: kwv yees li 0.3% molybdenum. Cov ntsiab lus no yog hloov:
- Creep Kuj:Nws tseem nce cov hlau lub zog ntawm qhov kub tshaj 400 degree, tiv thaiv kev deformation nyob rau hauv kev ntxhov siab tas li.
- Tem Siab Postrittlement Kuj: Nws pab tswj kev nruj tom qab kis tau rau kev ua haujlwm siab kub.
16mo3 vs. Cov hlau pob roj carbon ntau (P265GHGH, P295GHH)
Thaum tsis -}} alloy class zoo li P265GH yog qhov zoo heev rau General siab rau siab- lub luag haujlwm.
- P265GHGHGH / P295GHGH: Qhov zoo tagnrho rau kev kub siab. Lawv lub zog tau ntws tawm qhov kub thiab txias.
- 16MO3: Tshwj xeeb rau kev pab txhawb nqa kev pab txhawb nqa ntawm qhov kub txog li 550-600 degree. Nws qhov kev sib ntxiv ntawm molybdenum tso cai rau nws mus rau outperform cov hlau ntaus hauv cov chaw xav tau.
Cov Ntawv Qhia Tseem Ceeb ntawm 16MO3 Hlau
Boiler Nplooj Thiab Drums
Superheaters thiab cua sov sib pauv
High - kub cov hlab ntsha
Cov Khoom Piping Rau Cov Nroj Hluav Taws Xob
Tsis yog ib qho stainless hlau: 16mo3 yog qhov qis-} riam hlau. Rau kev ua kom zoo dua corrosion tsis kam, cov qhab nia tsis zoo (piv txwv li 304, 316) yuav tsum muaj.
Lub zog los ntawm aloying: nws siab - kub muaj peev xwm los ntawm molybdenum, tsis yog cov carbon xwb.
Foom cov phooj ywg: txawm hais tias nws cov ntsiab lus alloy, nws tuav tau zoo weldability thiab muaj peev xwm nrog cov txheej txheem txheem.
Nkag siab "vim li cas" qab cov ntaub ntawv muaj pes tsawg leeg yog qhov tseem ceeb rau kev xaiv cov khoom tseem ceeb rau lub zog, tshuaj lom neeg hauv ntiaj teb.

Cov FAQ
Q: Dab tsi yog sib npaug ntawm en 10028 16 mo3 hauv ASME / ASTM cov qauv?
A: Qhov ze tshaj plaws yog Astm A204 qib A lossis Qib A, uas tseem muaj kwv yees li 0.3% molybdenum.
Q: Qhov kev pabcuam kub tshaj plaws rau 16mo3 steel?
A: Nws yog feem ntau siv rau kev pab txhawb nqa mus txog 550 degree. Rau luv - kev pab rau lub sijhawm, nws tuaj yeem siv txog 600 degree, tab sis ib txwm sab laj cov qauv ntaub ntawv rau cov qauv tsim tshwj xeeb.
Q: yog 16mo3 steel corrosion - tsis kam?
A: Nws tau zoo tsis kam mus rau oxidation (scaling) ntawm qhov kub tshaj carbon hlau, tab sis nws tsis yog corrosion {} {resistant alloy rau tshuaj ib puag ncig. Tej zaum nws yuav xav tau kev tiv thaiv kev tiv thaiv rau kev siv sab nraud.
Q: Vim li cas yog cov lus faj sulfur hauv 16mo3 khaws cia tsawg?
A: Tsawg sulfur (tsawg dua los yog sib npaug rau 0.010%) yog qhov tseem ceeb rau kev ua kom muaj weldabry thiab nruj. Sulphur tuaj yeem tsim cov incusions uas ua rau tawg thaum lub sij hawm vuam thiab txo qis kev cuam tshuam lub zog.
