IS G3462 STBA 12 qib specification npog carbon steel kav rau kev pabcuam siab. Feem ntau yog siv rau sab hauv thiab sab nraud kev sib hloov cua sov hauv boilers thiab kub exchangers.
JIS G3462 STBA 12 tshav kub-resistant alloy yeeb nkab yog cov yeeb nkab zoo alloy steel feem ntau muaj cov ntsiab lus xws li chromium, molybdenum, thiab manganese, nrog lub zog tensile yam tsawg kawg nkaus ntawm 380 Mpa. Nws muaj qhov kub thiab txias tsis kam thiab tuaj yeem ua haujlwm hauv qhov kub thiab txias hauv qab 500 degree. Nws tuaj yeem siv los tswj qhov kub thiab txias tshaj tawm.
Tsis tas li ntawd, JIS G3462 STBA 12 qhov kub thiab txias seamless steel yeeb nkab kuj muaj kev ua haujlwm siab zoo thiab tuaj yeem tiv taus siab.
GNEE yog ib qho kev paub txog boiler thiab siab steel yeeb nkab xa khoom thiab tuaj yeem muab koj JIS G3462 STBA 12 kub boiler raj hauv txhua qib thiab qhov loj me.
