SA387 GR.21 CL1 cadaadiska weelka saxan bir ah

ASTM A387 Gr 21 CL 1 waa saxan bir ah oo chromium molybdenum alloy ah oo loogu talagalay kuleyliyaha alxanka iyo weelasha cadaadiska ee loogu talagalay adeegga heerkulka sare. Ka kooban Cr 3.00 % iyo Mo ka kooban 1.00 %. Darajo kasta marka laga reebo fasalka 21L, Fasalka 22L, Fasalka 91 iyo Fasalka 911 waxaa lagu heli karaa laba qaybood oo ah heerarka xoogga korantada. saxan bir daawaha loogu talagalay si gaar ah loogu isticmaalo weelasha cadaadiska birta kaarboon weldable heerkulka sare. Molybdenum-ka lagu daray waxa ay siinaysaa maaddada xoogga xajinta heer-kulka, chromium-kuna waxa uu bixiyaa iska caabbinta daxalka oo soo hagaagtay 11Class 1 waa nooc ka mid ah taarikada birta ee Cr-Mo-alloy ee loo isticmaalo in lagu dhejiyo weelasha cadaadiska heerkulka sare.A387 waxay leeyihiin toban darajo ama heerar. Waa fasalka 2aad, fasalka 12aad, fasalka 11aad, fasalka 22aad, fasalka 22aad, fasalka 21aad, 21L, fasalka 5, fasalka 9, 91.

Daawaynta kulaylka ee SA387 Chrom Moly Alloy Steel Plate

Saxanka birta birta ah ee moly alloy ee hoos yimaada ASME SA387 waa in la dilo birta, iyada oo kulayl ahaan lagu daaweeyaa iyada oo la tirtirayo, caadiyeynayo iyo dabci. Ama haddii uu ku heshiiyo iibsadaha, qaboojinta degdega ah ee heerkulka hagaajinta hawada hawada ama dareere deminta, oo ay ku xigto heerkulka, heerkulka heerkulka ugu yar waa inuu ahaadaa sida shaxda hoose:

Darajo	Heerkulka, °F [°C]
2, 12 iyo 11	1150 [620]
22, 22L, 21, 21L iyo 9	1250 [675]
5	1300 [705]
