1. Q: Dab tsi yog qhov tseem ceeb ntawm cov lus "H" hauv qib zoo li TP446H?
A:Cov lus "H" qhia txog qib uas yuav tsum tau ua kom muaj qhov kub thiab txias yield zog. Cov qib no muaj cov ntsiab lus nruj dua cov pa roj carbon monoxide kom ntseeg tau tias muaj kev tiv thaiv creep.
2. Q: Dab tsi yog qhov permissible weld kho qhov tob ntawm lub raj tiav?
A:Weld kho feem ntau tsis tso cai rau ntawm lub raj tiav yam tsis muaj kev pom zoo ua ntej ntawm tus neeg yuav khoom. Cov lus qhia tshwj xeeb tsom rau qhov zoo ntawm cov khoom raws li - tsim khoom.
3. Q: Cov tshuaj dab tsi yog qhov tseem ceeb rau kev tiv thaiv corrosion hauv Qib TP446?
A:Chromium (Cr). TP446 muaj cov ntsiab lus chromium siab (23.0 - 27.0%) uas muab kev tiv thaiv zoo rau oxidation thiab corrosion.
4. Q: Dab tsi yog qhov kev txhawj xeeb loj tshaj plaws thaum vuam ferritic stainless hlau zoo li TP430?
A:Kev loj hlob ntau dhau ntawm cov qoob loo hauv tshav kub- thaj chaw cuam tshuam (HAZ) tuaj yeem ua rau embrittlement thiab txo cov tawv nqaij. Kev tswj cov cua sov nkag thiab tom qab-weld annealing feem ntau tseem ceeb heev.
5. Q: Puas A268 / A268M cov raj yuav tsum tau soj ntsuam cov khoom los ntawm cov chaw tsim khoom?
A:Cov lus qhia tshwj xeeb yuav tsum muaj tshuaj ntsuam xyuas (kub ntsuas) los ntawm cov neeg tsim khoom steel. Kev tshuaj xyuas cov khoom yuav ua tau los ntawm tus neeg yuav khoom, nrog rau kev zam tau teev tseg hauv cov lus qhia tshwj xeeb.
