Nuxurka Alloy ee Plate Moly Chrome
Qalabka moly-chrome ee hoos yimaada ASTM A387 ee darajooyinka server-ka oo leh waxyaabo ka kooban alloy kala duwan sida hoose, darajooyinka isticmaalka guud waa Gr 11, 22, 5, 9 iyo 91.
Marka laga reebo 21L, 22L iyo 91, darajo kasta waxaa lagu heli karaa laba qaybood oo ah heerarka xoogga xajinta sida lagu qeexay jaantusyada shuruudaha xajinta. Fasalada 21L iyo 22L waxay leeyihiin kaliya Fasalka 1, iyo Fasalka 91 wuxuu leeyahay oo kaliya Class2.
Darajo | Macnaha Chromium, % | Nuxurka Molybdenum magac ahaan, % |
2 | 0.50 | 0.50 |
12 | 1.00 | 0.50 |
11 | 1.25 | 0.50 |
22, 22L | 2.25 | 1.00 |
21, 21L | 3.00 | 1.00 |
5 | 5.00 | 0.50 |
9 | 9.00 | 1.00 |
91 | 9.00 | 1.00 |

Daawaynta kulaylka ee A387 Chrom Moly Alloy Steel Plate
Saxanka birta birta ah ee moly alloy ee ka hooseeya ASTM A387 waa in la dilo birta, iyada oo kulayl ahaan loola dhaqmo 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] |
Fasalka 91 taarikada birta daawaha ah waa in lagu daaweeyaa kulayl caadiyadejin iyo qaboojin ama qaboojin degdeg ah hawo qarxin ama dareere deminta, oo ay ku xigto dabci. Fasalka 91 taarikada waxay u baahan yihiin in la hagaajiyo 1900 ilaa 1975°F [1040 ilaa 1080°C] waana in lagu kululeeyaa 1350 ilaa 1470°F [730 ilaa 800°C]
Fasalka 5, 9, 21, 21L, 22, 22L, iyo 91 saxan lagu dalbado iyada oo aan lagu daawayn kulaylka miiska sare, waa in lagu dhammeeyaa xaalad walbahaarka la khafiifiyo ama la daboolay.
