P275NL1 Steel Phaj: Specifications thiab Properties
P275NL1 yog European txheem steel phaj npaj rau boilers thiab siab hlab ntsha. Nws yog ib tug normalized, weldable nplua - nplej hlau ua raws li covTS EN 10028-3standard, nrog rau cov khoom siv tooj1.0488.
Nws Z-kev taw qhia kev ua tau zoo (los ntawm- cov khoom tuab) tau muab faib ua peb qib:Z15, Z25, thiab Z35, uas yog tsim los ua kom tau raws li qhov yuav tsum tau muaj rau lamellar tearing resistance nyob rau hauv qis -kub ib puag ncig.
Tsis tas li ntawd, nws pom zoo hydrogen tsis kam. Thaum raug corrosive H₂S ib puag ncig (feem ntau hu ua "kev pabcuam qaub"), carbon thiab qis- alloy steels tuaj yeem raug tawg. Yog li ntawd, cov ntawv hlau tuaj yeem raug ntsuas rau Hydrogen-Induced Cracking (HIC) tsis kam. Qhov dhau los ntawm -thickness kev ua tau zoo rau P275NL1 yog Z15, Z25, thiab Z35, thiab cov khoom siv tshwj xeeb muaj qib yogP275NL1Z15, P275NL1Z25, thiab P275NL1Z35.
Cov qib kev kawm muaj feem cuam tshuam hauv tib yam xws li: P275NL1, P275NL2, P355NH, P355NL1, P355NL2, P420NH, P420NL1, P420NL2, P460NH, P460NL1, thiab P460NL2.
Delivery condition:
P275NL1 steel phaj feem ntau yog xa hauvnormalized (+ N)mob. Los ntawm kev pom zoo ntawm tus neeg yuav khoom thiab cov chaw tsim khoom, normalizing dov (+N) tuaj yeem siv los hloov lub cub tawg normalizing. Hauv cov xwm txheej zoo li no, cov qauv kuaj yuav tsum raug simulated normalizing ntawm qhov pom zoo- raws li kev sim zaus los xyuas kom meej tias cov khoom siv tshuab ua tau raws li qhov yuav tsum tau ua.

Hydrogen{0}}Induced Cracking (HIC) Resistance ntawm P275NL1
Cov pa roj carbon monoxide thiab qis- alloy steels tej zaum yuav raug cuam tshuam rau kev tawg thaum raug rau qhov chaw corrosive uas muaj H₂S (feem ntau hu ua "kev pabcuam qaub"). Thaum lub sijhawm nug thiab kev txiav txim, kev ntsuam xyuas los ntsuas HIC kuj tuaj yeem ua raws li cov kev cai hauv qab no.
Kev ntsuam xyuas ntawm HIC Resistance:Kev ntsuam xyuas yuav tsum ua raws liTS EN 10229los soj ntsuam cov khoom hlau tsis kam rau hydrogen-induced cracking. Cov txheej txheem lees txais rau Kev Xeem A (pH ≈ 3) siv rau cov chav kawm uas tau teev tseg, qhov twg tus nqi muab yog qhov nruab nrab ntawm peb tus neeg tau txais kev xeem. Thaum lub sijhawm nug thiab kev txiav txim, kev siv Test Solution B (pH ≈ 5) thiab nws cov txheej txheem lees txais yuav raug pom zoo.
Cov khoom siv
