Q235A poleiti ea tšepe

Letlapa la tšepe la boiler le sebelisoa haholo ha ho etsoa li-boilers tse fapaneng le lisebelisoa tsa bohlokoa. Kaha poleiti ea tšepe ea boiler e sebetsa ka mocheso o bohareng (ka tlase ho 350 ° C) le khatello e phahameng, ho phaella khatellong e phahameng, e boetse e tlas'a tšusumetso, mokhathala le mouoane oa metsi. Hoa hlokahala ho netefatsa matla a itseng, 'me e na le ts'ebetso e ntle ea welding le e batang ea ho koba. Limaraka tse tloaelehileng: Q245R, A5155 grade 55, A5156 grade 60, Q235A carbon steel plate, A5166 grade 65, A51670 grade.

Bolelele ba tšepe e matla e tlase ea alloy ke 15% -23%, 'me matla a ho monya matla ka mocheso oa kamore e kholo ho feta 34J. Q235A carbon steel plate, low alloy high strong steel steel e na le polasetiki e ntle le ho hanyetsa tšusumetso, e ka qobang ho robeha ha brittle nakong ea tšusumetso le ho etsa hore ho kobeha ha serame le ho tjheseletsa ho be bonolo. Ho phaella moo, mocheso oa phetoho ea brittle ea tšepe e tlaase ea alloy e matla e tlaase, 'me boleng ba ho sebetsa ba tšepe ea E-grade ho -40 ° C ha bo ka tlase ho 27J. Sena se bohlokoa haholo bakeng sa likarolo tsa boenjiniere le mekhoa ea lipalangoang joalo ka likoloi, likepe, sethala sa oli sa kantle ho naha, lijana, marokho, jj.
