1. Q: Dab tsi yog qhov Scope ntawm DIN 17175 tus qauv?
A:DIN 17175 siv rauseamless rajua los ntawm cov cua sov-cov hlau tsis muaj zog uas tau teev tseg hauv tus qauv. Cov raj no yog siv rau hauv kev tsim cov chav boilers, cov kav dej, cov hlab ntsha siab, thiab kev ntsuas kev ua haujlwm ntawm qhov kub thiab txias mus txog.600 degree, qhov twg siab - kub lub zog thiab tshwj xeeb oxidation kuj yuav tsum tau-3-4.
2. Q: Cov qib steel twg tau teev tseg raws li DIN 17175?
A:Tus qauv npog ntau qhov cua sov-cov qib steel resistant. Ib qho siv feem ntau yog13 CrMo44, chromium -molybdenum alloy steel paub rau nws siv hauv cov hlab ntsha siab
3. Q: Dab tsi yog cov khoom tseem ceeb ntawm 13CrMo44 alloy steel ib DIN 17175?
A:13CrMo44 alloy steel muaj kev sib xyaw ua ke ntawmsiab toughness thiab siab zog, nrog rau kev ua haujlwm zoo rau hnav, qaug zog, corrosion, thiab cuam tshuam. Nws kuj muaj kev ua haujlwm zoo heev thiab formability-2.
4. Q: Dab tsi yog qhov tseem ceeb ntawm DIN 17175 raj?
A:Cov raj no feem ntau yog siv hauv cov haujlwm uas xav tau siab - kub thiab siab ua haujlwm, xws liCov hlab ntsha siab, kev tsim boiler, cov cuab yeej tsim hluav taws xob, thiab cov chaw tsim hluav taws xob nuclear-2.
5. Q: Dab tsi yog qhov tseem ceeb ntawm kev sib tw vuam rau cov kav dej ua los ntawm cov ntaub ntawv zoo li 13CrMo44?
A:Thawj qhov teeb meem ntawm vuam muaj xws lihardening nyob rau hauv lub tshav kub - cuam tshuam cheeb tsam (HAZ) thiab txias cracking. Tseem muaj kev pheej hmoo ntawmrov ua kom tawgthaum lub sij hawm tom qab-weld kev kho cua sov los yog tom qab lub sij hawm ntev raug rau siab kub nyob rau hauv kev pab cuam
