SA387 GR.12 CL2 Pressure Vessel Steel plate

Fa'ainisinia mo le fa'aogaina i le maualuga o le vevela auaunaga, ASME SA387 Vasega 12 o le chrome molybdenum carbon alloy steel mo le fa'aogaina i va'a mamafa ma fa'avela fale gaosi oloa.
SA387 GR.12 CL2 Pressure Vessel Steel plate Fa'amatalaga:
A387 Vasega 12 CL 1, A387 Vasega 12 CL 2 o loʻo i lalo o le faʻamatalaga uʻamea tulaga masani ASTM A387 / A387M mo ipu uʻamea uʻamea ipu, uamea faʻafefiloi ma Chromium-Molybdenum.O le ipu uamea tutusa SA387 Vasega 12 CL 1 ma SA387 Vasega 12 CL 2 o loʻo i lalo o Amerika uamea stamdard SA 387 / SA 387M.All nei uʻamea uʻamea ipu ua faamoemoe faapitoa mo boilers uelo ma vaʻa mamafa & tanks.Rolling mafiafia aupito maualuga o papatusi ua faatapulaaina na o le gafatia o le tuufaatasiga e ausia ai manaoga faapitoa o meatotino.
Mo ipu uamea ipu mamafa SA387 Vasega 12 CL 1, o le tensile malosi e tatau ona i totonu o le 380 i le 550, maualalo maua malosi o le 230 Mpa. Mo SA387 Vasega 12 CL 2 ipu mamafa ipu uamea, o le malosi tensile i le 450-585 Mpa ma maua. mata e tatau ona i luga o le 275 Mpa. E ese mai i elemene autu e lima, o loʻo i ai foi Cr-Mo i le vailaʻau vailaʻau mo nei uʻamea uʻamea.

Togafitiga vevela mo SA387 Chrom Moly Alloy Plate uamea

Chrome moly u'amea ipu uamea i lalo ASME SA387 e tatau ona fasiotia uʻamea, ma thermally togafitia e ala i annealing, normarlizing ma tempering. Po'o le tulaga ua malilie i ai le tagata fa'atau, fa'avaveina le mālūlū mai le vevela fa'aaustenitizing e ala i le fa'afefe o le ea po'o le tineia o le vai, soso'o ai ma le fa'afefeteina, e tatau ona fa'apena le la'ititi la'ititi o le vevela fa'afefeteina:
Vasega Vevela, °F [°C]
2, 12 ma le 11 1150 [620]
22, 22L, 21, 21L ma le 9 1250 [675]
