SA387 GR.12 CL2 Pressure Vessel Steel plate

I-A387 iBanga le-12 CL 1, i-A387 iBanga le-12 i-CL 2 iphantsi komgangatho wensimbi ye-ASTM A387 / A387M yeeplate zentsimbi yoxinzelelo, i-alloy steel ne-Chromium-Molybdenum. ziphantsi American steel stamdard SA 387/SA 387M.Zonke ezi iipleyiti intsimbi ingxubevange ezijoliswe ngokuyintloko kwiibhoyila ezidityanisiweyo kunye nemikhumbi yoxinzelelo & tanks.Ukuqengqeleka ubukhulu iipleyiti kunqandwa kuphela umthamo wokwakheka ukuhlangabezana neemfuno ezichaziweyo mechanical impahla.
Ngoxinzelelo lwesitya sentsimbi yesitya se-SA387 iBanga le-12 CL 1, amandla okuqina aya kuba phakathi kwe-380 ukuya kwi-550, amandla amancinci angama-230 Mpa. Kwi-SA387 iBanga le-12 CL 2 isitya soxinzelelo lwesitya sentsimbi, amandla e-tensile kwi-450-585 Mpa kunye nesivuno. inqaku liya kuba ngasentla kwe-275 Mpa. Ngaphandle kwezinto ezintlanu eziphambili, i-Cr-Mo ikwakubunjwa beekhemikhali kwezi zintsimbi zealloy.

Unyango loBushushu lwe-SA387 Chrom Moly Alloy Steel Plate

I-Chrome moly alloy steel plate phantsi kwe-ASME SA387 iya kubulawa intsimbi, iphathwe ngokushushumbisa nokuba kufakwe i-annealing, i-normarlizing kunye nokufudumeza. Okanye kwimeko ekuvunyelwene ngayo ngumthengi, ukupholisa okukhawulezileyo ukusuka kwiqondo lobushushu le-austenitizing ngokuqhushumba komoya okanye ukucinywa kolwelo, kulandelwa kukufudumeza, amaqondo obushushu asezantsi ayakuba njengalapha ngezantsi kwetheyibhile:
