Alloy Tsim thiab Metallurgical Cov Qauv
Qib P22 belongs rau lubChav kawm ferritic-temperedntawm cov hlau. Nws cov kev ua tau zoo los ntawm ib qho kev tsim kho microsered microstructure muaj litempered ferrite thiab ruaj khov chromium-molybdenum carbides (M₂₃c₆, M₆C).
| Alloy keeb | Cov ntsiab lus (%) | Lub luag haujlwm hauv kev ua tau zoo |
|---|---|---|
| CR (chromium) | 1.90 – 2.60 | Ua cov txheej oxide tiv thaiv thiab txhim kho cov ntsuas ntsuas tsis kam tiv taus |
| Mo (Molybdenum) | 0.87 – 1.13 | Muab cov kua -}} kev tov khoom ntxiv thiab nkag mus |
| C (carbon) | 0.05 – 0.15 | Kev tswj hwm lub hardness thiab ductancable sib npaug |
| Mn (manganese) | 0.30 – 0.60 | Txhim kho Weldability thiab tawv |
| Si (silicon) | 0.50 – 1.00 | Txhim kho cov oxidation thiab corrosion tsis kam |
| P / S | Tsawg dua los yog sib npaug rau 0.025 | Tswj hwm ductility thiab tiv thaiv qoob loo ciam teb brittleness |
Qhov kev teeb tsa metallurgical no kom ntseeg tau:
- Ruaj khov ferrite - carbide microstructuretiv taus coarsening nyob rau hauv thermal load.
- Nkag reep - rupture ruaj khovHla 100,000 teev cov kev pabcuam ntawm 540-600 degree.
- Zoo heev Weld muaj kev ncaj nceesThaum Post - weld cua sov {}}}} kho (pwht).
- Tswj Oxidation Scaling, txo cov raj nplaim roughness thiab hlau wastage.
Mechanical NTSEEG THIAB Kub Kuj
| Ntiag tug | Qhov toob kas | Engineering Lub Hom Phiaj |
|---|---|---|
| Lub zog tensile | Ntau dua los yog sib npaug rau 415 MPa (60 ksi) | Withstands ntev - lub sij hawm axial ntxhov siab |
| Paib lub zog | Ntau dua los yog sib npaug rau 205 MPa (30 ksi) | Tiv thaiv kev tiv thaiv yas |
| Elongation | Ntau dua los yog sib npaug rau 30% | Muab FOORICATION DRIVILIS |
| Kev nyuaj | Tsawg dua los yog sib npaug rau 163 hbw | Txhim Kho Weld Tougness Thiab Qoob Luv Ncuas Ncauj |
Ntawm kev nce qib kub, P22 tswj ibnkag ov - rupture lub zog saum 60 mpa ntawm 600 degree, khaws nws cov duab thiab kev ncaj ncees txawm nyob hauv lub siab ua tiav thiab kev co.
Kev Raug Tshuab Thiab Kho Cua Sov
Tsis zoo li cov hlau nplaum qis dua, P22 yuav tsum muaj tseebThermal-Neeg Khothoob plaws tsim khoom.
Octal Yeeb Nkab ntiav cov txheej txheem kev sib txuas ua ke nrogNtau - theem kev kho cua sovTxhawm rau kom ntseeg tau tias nws yog xim hlau uniformity thiab sab nraud precision.
Kev tsim khoom:
- Billet Tho & Txoj Kev Lom Zem Kub- Cr - mo billces yog chob ntawm 1100-1150℃siv extrusion extrusion.
- Mob khaub thuas drawuction / Kub Rolling- Ua kom qhib cov qoob loo loj thiab phab ntsa sib dhos.
- Normalization (940-980 Qib)- Ua kom muaj cov nplej ferritic nplej thiab yaj tau cais carbides.
- Tempering (675-760 degree)- Relieves sab hauv kev ntxhov siab, restores ductility, thiab stabilizes carbides.
- Hydrostatic / Ultrasonic Kuaj- Siv tau lub siab muaj peev xwm thiab lub suab zoo.
TusDual -} theem kub kho(normalize + Tauj) yog qhov tseem ceeb. Nws yields zoo {{2} nplej, tempered ferrite mibrix, txhawb nqa kev nkag siab weld, thiab muab kev txiav txim siab paub txog ntau xyoo dhau los ntawm kev pabcuam.
