FAQ
1.Dab tsi yog cov qib alloy steel feem ntau siv hauv boilers thiab fais fab nroj tsuag?
Cov qib uas nquag siv feem ntau suav nrog2Cr12NiMo1W1V, 12Cr1MoV, P91 (9Cr1MoVNb), P92, 20Cr1Mo1VTiB, thiab1Cr11Ni2W2MoV. Cov hlau no muab lub zog nkag siab, tiv thaiv tshav kub, thiab lub neej ua haujlwm ntev nyob rau hauv siab - kub thiab siab - siab.
2.Yuav ua li cas kuv thiaj xaiv cov hlau alloy zoo rau qib siab -kub siv?
Kev xaiv nyob ntawm qhov kub thiab txias, siab, ib puag ncig corrosion, thiab mechanical load. Rau qhov kub siab tshaj 600 degree,P91, P92, thiab 2Cr12NiMo1W1Vnyiam. Rau cov tshuaj tiv thaiv, Cr-Ni-Mo steels nyiam1Cr18Ni9 los yog 25Cr2MoVAtsim nyog.
3.Dab tsi yog cov qauv thoob ntiaj teb thiab sib npaug rau cov qib hlau alloy?
Cov qauv tseem ceeb suav nrogGB, ASTM, ASME, DIN, EN, thiab JIS. Piv txwv li:
- 2Cr12NiMo1W1V (GB) ≈ ASTM 617 / P91
- 12Cr1MoV (GB) ≈ ASTM A335 P11
- 25Cr2MoVA (GB) ≈ DIN 1.7335
4.Yuav ua li cas alloy hlau yuav muab nyob rau hauv seamless thiab welded hom?
Yog lawm, alloy steel muaj nyob rau hauv seamless, ERW (Electric Resistance Welded), kub- dov, thiab txias- daim ntawv kos. Qhov kev xaiv nyob ntawm cov yeeb nkab txoj kab uas hla, phab ntsa thickness, thiab daim ntawv thov yuav tsum tau.
5.Dab tsi yog cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm alloy steels?
Txhua qib muaj cov ntsiab lus C, Cr, Mo, Ni, V, W, cuam tshuam lub zog tensile, hardness, creep, thiab qaug zog. Piv txwv li:
- 2Cr12NiMo1W1V: 0.12%C, 12%Cr, 1%Mo, 1%Ni, 0.2%V, 1%W, 750–900 MPa tensile, 250–280 HB hardness.
- P91: 0.09%C, 9%Cr, 1%Mo, 0.07%V, 690–830 MPa tensile, 230–260 HB hardness.
6.Puas kev cai qhov ntev thiab specifications muaj?
Yog lawm, peb muab kev cai OD, phab ntsa thickness, ntev, thiab cov duab rau alloy steel tuav, raj, thiab kav. Ob qhov metric thiab imperial loj tuaj yeem muab tau raws li cov neeg siv khoom lossis cov haujlwm xav tau.
7.Yuav ua li cas yog qhov zoo ntawm alloy steel guaranteed?
Cov khoom yog tsim nyob rau hauv ISO 9001 thiab API 5L cov txheej txheem ntawv pov thawj, kuaj lub zog tensile, hardness, cuam tshuam, thiab tsis yog -kev kuaj kev puas tsuaj (UT, PT, RT). Thib peb-kev tshuaj ntsuam xyuas thiab Mill Test Certificate (MTC) tau muab.
8.Dab tsi yog cov ntawv thov tseem ceeb ntawm cov hlau hlau hauv kev lag luam?
Alloy steel yog dav siv nyob rau hauv: boilers, superheaters, petrochemical pipelines, siab hlab ntsha, tshav kub exchangers, aerospace, nuclear, marine engineering, automotive, thiab hnyav machinery.
9.Yuav ua li cas mus cuag lub neej kev pab cuam ntawm alloy steel khoom?
Kev kho cua sov kom zoo, txo kev ntxhov siab, tiv thaiv corrosion, thiab kev tshuaj xyuas tsis tu ncua yog qhov tseem ceeb. Xaiv cov qib raug rau qhov chaw ua haujlwm ua rau txo qis hnav, nkag, thiab qaug zog.
10.Cas alloy steel yuav welded los yog machined yooj yim?
Cov hlau alloy feem ntau yog weldable thiab machinable, tab sis qib zoo li siab -chromium los yog siab-vanadium steels yuav xav tau preheating thiab tswj ncej-weld tshav kub kho kom muaj zog txhua yam.
