GB 18MnMoNbg GB 713
Boiler thiab Pressure Vessel SteelKhoom Taw Qhia
Nyob rau xyoo 1890, Suav engineers pib tsim ib hom tshiab boiler steel uas tiv taus qhov kub thiab txias ntau dua, hu ua GB 18MnMoNbg GB 713. Cov hlau muaj cov pa roj carbon monoxide, nrog rau manganese, chromium, thiab lwm yam hlau. Qhov kev sib xyaw ua ke ntawm cov ntaub ntawv no tau tsim los ua kom cov hlau tiv taus cua sov thiab xeb, ua rau nws nyob deb dua thiab muaj zog dua li cov tsoos cam khwb cia hlau boilers.
Peb lub tuam txhab muaj steel khoom billets, steel khoom, kub dov los xij, txias-draw los xij, seamless steel kav, steel tuav thiab lwm yam khoom.GB 18MnMoNbg GB 713muaj lub koob npe nrov hauv kev ua lag luam, cov khoom lag luam zoo, thiab kev xav zoo hauv kev lag luam steel. GB 18MnMoNbg GB 713 tau ua tiav cov lus qhia tshwj xeeb, thiab cov khoom siv dav siv hauv aerospace, petrochemical, thiab kev tsim kho cov haujlwm, nrog rau cov khoom siv tsawg, kev ua haujlwm yooj yim thiab qhov yuav tsum tau muaj qhov tseeb tsawg. Thiab muab kev txiav, khoov, vuam, drilling, thiab lwm yam kev pabcuam.
Daim ntawv thov:Cov pa roj carbon steel thiab qis alloy steel phaj rau boiler.
Thaum tshav kub kub kho:1867 degree - 1528 degree .
