ASME Q245R ASME SA / GB 713 Boiler Steel Phaj
nkoj steel phaj Khoom Taw qhia
Ib qho ntawm qhov zoo tshaj plaws ntawm ASME Q245R ASME SA / GB 713 steel phaj yog nws cov khoom zoo heev los tiv thaiv. Lub phaj muaj peev xwm tiv taus kev ua haujlwm hnyav hauv qhov kub ntawm 500 degree -650 degree . Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv kub kub xws li cov khoom siv boiler thiab cov hlab ntsha. Tsis tas li ntawd, txij li cov hlau no muaj cov ntsiab lus carbon tsawg heev, nws tsis tshua muaj kev tiv thaiv rau inter-granular corrosion, tshwj xeeb tshaj yog thaum muaj dej thiab chav.
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.ASME Q245R ASME SA/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. ASME Q245R ASME SA / 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 tsawg tsawg qhov tseeb. Thiab muab kev txiav, khoov, vuam, drilling, thiab lwm yam kev pabcuam.
Daim ntawv thov:Specification rau Steel Phaj rau Boilers thiab Siab Vessels.
Thaum tshav kub kub kho:1268 degree - 1546 degree .

ASME Q245R ASME SA / GB 713 Cov Khoom Siv Tshuaj
ASME Q245R ASME SA / GB 713 ntxiv rau cov pa roj carbon, hlau kuj tseem muaj ib qho me me ntawm manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) thiab hydrogen. (H). Cov ntsiab lus no tsis txhob txwm ntxiv los txhim kho cov hlau zoo, tab sis raug coj los ntawm cov txheej txheem ore thiab smelting, yog li lawv hu ua impurity ntsiab. Cov impurities no muaj qee yam cuam tshuam rau cov khoom ntawm cov hlau. Txhawm rau kom ntseeg tau qhov zoo ntawm cov hlau, cov tshuaj muaj pes tsawg leeg ntawm txhua yam hlau yog nruj me ntsis raws li cov qauv kev.
