Taw qhia rau 10CrMo9-10 Carbon Steel Boiler Pipe
10CrMo9-10yog ib qho qis- alloy cua sov- cov hlau resistant dav siv nyob rau hauv kev tsim cov hlab ntsha siab, boilers, thiab siab - cov kav dej kub. Nws lub npe ua raws li European tus qauv EN 10216-2. Cov lej thiab cov tsiaj ntawv hauv nws lub npe qhia nws cov ntsiab lus tseem ceeb alloying: kwv yees li1% Chromium (Cr)thiab0.9-1.2% Molybdenum (Mo), nrog cov ntsiab lus carbon nyob ib puag ncig0.10%.
Lub ntsiab kom zoo dua ntawm 10CrMo9-10 nyob rau hauv nwsenhanced creep kuj thiab elevated kub zog. Qhov sib ntxiv ntawm molybdenum txhim kho cov hlau lub zog ntawm qhov kub thiab txias thiab txo qhov cuam tshuam rau temper embrittlement. Chromium pab txhim kho oxidation thiab corrosion kuj piv rau cov pa roj carbon steels. Qhov kev sib xyaw ua ke no ua rau nws tsim nyog rau lub sijhawm ntev - kev pabcuam hauv ib puag ncig uas muaj qhov kub thiab txias txog li kwv yees580℃(1076℃F).
Cov ntawv thov raug suav nrog:
Superheater thiab reheater raj nyob rau hauv lub hwj chim chaw nres tsheb boilers
Siab - kub taub hau thiab chav kab
Thaum tshav kub kub exchangers nyob rau hauv cov txheej txheem industries
Cheebtsam hauv cov nroj tsuag petrochemical
Cov hlau no feem ntau muab nkag rau hauv cov xwm txheej zoo li qub thiab ua kom muaj kev pom zoo microstructure uas sib npaug zog, ductility, thiab toughness.
Cov yam ntxwv tseem ceeb thiab cov khoom ntawm 10CrMo9-10
Cov lus hauv qab no qhia txog cov yam ntxwv tseem ceeb thiab cov ntsiab lus ntawm 10CrMo9-10 steel yeeb nkab raws li cov qauv sib txawv.
Cov lus: Cov ntsiab lus ntawm 10CrMo9-10 Boiler Steel Pipe
| Yam khoom | Paub meej / Hom Tus Nqi |
|---|---|
| Khoom Txheem | TS EN 10216-2: Seamless steel raj rau lub hom phiaj siab |
| Qib sib npaug | ASTM / ASME: A335 P12, DIN:13CrMo4-5,JIS:SIB 22,GB:15 CrMoG |
| Tshuaj muaj pes tsawg leeg | C: 0.08-0.14%, Si:Tsawg dua lossis sib npaug li 0.35%,Mn: 0.40-0.80%, P:Tsawg dua lossis sib npaug li 0.025%,S:Tsawg dua lossis sib npaug li 0.015%,Cr: 2.00-2.50%, Mo: 0.90-1.20% |
| Mechanical Properties (ntawm chav tsev temp) | Yield zog (Rp0.2):Ntau dua lossis sib npaug li 280 MPa,Tensile zog (Rm):460-590 MPa,Elongation (A):Ntau dua lossis sib npaug li 22% |

| Qhov Zoo Tshaj Plaws | Weldability zoo (nrog ua ntej- thiab tom qab-weld kev kho cua sov), Zoo heev creep zog, Txhim kho oxidation kuj piv rau C-Mo steels |
| Cov ntawv thov tseem ceeb | Siab -kub cov kav dej thiab cov kav dej hauv lub zog tsim hluav taws xob, cov boilers muaj, thiab cov nroj tsuag petrochemical. |
Cov Lus Qhia Tseem Ceeb rau Daim Ntawv Thov:
Vuam:Thaum nws muaj qhov zoo weldability, cov txheej txheem tsim nyog yuav tsum tau ua raws. Ua ntej- cua sov (200-300 degree) thiab tom qab vuam cua sov kho (PWHT) nyob ib ncig ntawm 650-700℃feem ntau yuav tsum tau ua kom tsis txhob muaj qhov txias txias thiab txo qis kev ntxhov siab.
Corrosion Resistance:Txawm hais tias nws muaj oxidation zoo dua li carbon steel, nws tsis yog stainless hlau. Rau ib puag ncig uas muaj kev xeb tseem ceeb los yog xav tau oxidation ntau dua, cov hlau alloy siab dua (xws li, muaj ntau dua Cr) yuav tsum xav txog.
Kev ua raws cai:Nco ntsoov xyuas kom meej tias cov khoom tau muab nrog cov ntawv pov thawj tsim nyog (piv txwv li, EN 10204 3.1/3.2) thiab ua tau raws li cov cai tshwj xeeb ntawm tus qauv tsim (xws li EN 12952, ASME BPVC).
