ASME SA 387 GRADE 12 Kalasi 1 zitsulo

ASME SA 387 GRADE 12 Class 1,ASME SA387 Grade 12 Alloy Steel Plates
Chopangidwa kuti chigwiritsidwe ntchito pa kutentha kwakukulu, ndi chitsulo cha chrome molybdenum carbon alloy kuti chigwiritsidwe ntchito muzotengera zowotcherera zowotcherera ndi ma boiler a mafakitale.
Zomwe zimapindula ndi chromium yowonjezeredwa yomwe imapereka dzimbiri komanso kukana kwa okosijeni kupangitsa kuti ikhale yabwino pakugwiritsa ntchito ntchito zowawa pamakampani amafuta ndi gasi.
