SA204 Qib B Siab Vessel Steel yog cov pa roj carbon zoo tshaj-molybdenum (C-Mo) alloy steel phaj tsim nyob rau hauv nruj ua raws li ASME SA204 tus qauv, tshwj xeeb tsim rau fabricating nruab nrab thiab siab- cov hlab ntsha siab ua haujlwm nyob rau hauv qhov kub thiab txias. Raws li kev lees paub dav dav dav hlau qib steel qib hauv kev lag luam hlau thoob ntiaj teb, nws cov txiaj ntsig tseem ceeb nyob hauv kev tshawb fawb ntxiv ntawm molybdenum, uas ua rau muaj txiaj ntsig zoo rau cov khoom siv thermal stability, creep resistance, thiab siab - kub txhua yam lub zog piv rau cov pa roj carbon zoo tib yam.
Gneesteel tshwj xeeb hauv kev muab ASME SA204 steel phaj hauv SA204 Qib B. Yog xav paub ntxiv ntawm SA204 Qib B steel phaj, thov xyuas lawv hauv qab no:
