Waxyaabaha Daawaha ah ee Saxanka Chrome Moly

Saxanka moly-ga ee Chrome ee hoos yimaada ASTM A387 ee darajooyinka serveral-ka ah oo leh waxyaabo kala duwan oo daawaha ah sida hoos ku xusan, darajooyinka isticmaalka caadiga ah waa Gr 11, 22, 5, 9 iyo 91.

Marka laga reebo 21L, 22L iyo 91, darajo kasta waxaa laga heli karaa laba fasal oo heerarka xoogga jiidista ah sida ku qeexan jaantusyada shuruudaha jiidista. Darajooyinka 21L iyo 22L waxay leeyihiin oo keliya Fasalka 1, Darajada 91na waxay leedahay oo keliya Fasalka 2.

Daaweynta Kulaylka ee Saxanka Birta ee A387 Chrom Moly Daawaha

Saxanka birta ah ee chrome moly ee hoos yimaada ASTM A387 waa in la dilo birta, iyadoo lagu daweynayo heerkul ahaan iyadoo la isku dayo, la isku hagaajiyo oo la isku hagaajiyo. Ama haddii iibsaduhu ogolaado, qaboojinta degdega ah ee heerkulka astenitizing iyadoo la adeegsanayo qarax hawo ama damin dareere ah, oo ay ku xigto heerkulbeeg, heerkulka ugu yar ee heerkulbeeggu waa inuu ahaadaa sida hoos ku xusan:

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

Taarikada birta ah ee dahaarka leh ee heerka 91 waa in lagu daaweeyaa kulayl iyadoo la caadiyeynayo oo la kululeynayo ama qaboojin degdeg ah iyadoo la adeegsanayo qarax hawo ama damin dareere ah, ka dibna lagu kululeynayo. Taarikada heerka 91 waa in lagu kululeeyo 1900 ilaa 1975°F [1040 ilaa 1080°C] waana in lagu kululeeyaa 1350 ilaa 1470°F [730 ilaa 800°C]

Taarikada fasalka 5aad, 9aad, 21aad, 21aad, 22aad, 22aad, iyo 91aad ee lagu dalbaday iyada oo aan lagu daweyn kulaylka miiska kore, waa in lagu dhammeeyaa xaalad cadaadis yar ama mid la buufiyay.
