FAQ
Q: Qhov txawv ntawm TP321H thiab TP347H yog dab tsi?
A: TP321H yog alloyed nrog titanium (Ti), thaum TP347H yog alloyed nrog niobium (Nb). Txij li thaum niobium carbides ruaj khov dua li titanium carbides, TP347H tuaj yeem muab kev ua tau zoo me ntsis hauv cov cheeb tsam tshuaj lom neeg hnyav lossis cov ntawv thov cuam tshuam nrog kev rov ua dua vuam. TP321H feem ntau yog tus nqi ntau dua- siv tau thiab yooj yim dua rau qhov chaw tshaj TP347H, ua rau nws yog tus qauv xaiv rau feem ntau siab -kub muaj piping applications.
Q: Puas yog TP321H piping yuav tsum tau ncej-weld heat treatment (PWHT)?
A: Feem ntau, tsis yog. Raws li TP321H yog qib stabilized, cov tshuaj annealing feem ntau tsis tas yuav tsum tau tom qab vuam los kho corrosion kuj. Txawm li cas los xij, nyob rau hauv tej yam kub siab heev los yog corrosive ib puag ncig, tsim specifications yuav tsum stabilization annealing ntawm 845℃-900℃los xyuas kom meej tag nrho kev sib raug zoo ntawm carbon nrog titanium, yog li ua tau zoo corrosion kuj.
Q: Dab tsi yog hom kev ua tsis tiav rau TP321H?
A: Txawm hais tias nws qhov siab -kub tsis kam, TP321H muaj qhov cuam tshuam rau kev ntxhov siab corrosion tawg nyob rau hauv qhov chaw ntub dej uas muaj chloride ions. Kev raug kub ntev ntev ntawm 590℃thiab 870℃tuaj yeem ua rau nag lossis daus ntawm sigma (Σ) theem nyob rau hauv cov khoom, ua rau txo qis hauv chav- kub toughness (txawm hais tias toughness ntawm siab kub yog khaws cia).
