Chithandizo cha Kutentha kwa A387 Chrom Moly Alloy Steel Plate

Chitsulo cha Chrome moly alloy zitsulo pansi pa ASTM A387 chidzaphedwa chitsulo, ndi kutenthedwa ndi kutentha, kutentha, kutentha ndi kutentha. Kapena ngati wogula avomereza, kuziziritsa kofulumira kuchokera ku kutentha kozizira kwambiri ndi kuphulika kwa mpweya kapena kuzimitsa kwamadzimadzi, kutsatiridwa ndi kutentha, kutentha kochepa kudzakhala monga pansipa:

Gulu	Kutentha, °F [°C]
2, 12 ndi 11	1150 [620]
22, 22L, 21, 21L ndi 9	1250 [675]
5	1300 [705]

Zitsulo zazitsulo zamtundu wa 91 ziyenera kutenthedwa ndi kutentha ndi kutentha kapena kuzizira kofulumira ndi kuphulika kwa mpweya kapena kuzimitsa kwamadzimadzi, kutsatiridwa ndi kutentha. Ma plates a Giredi 91 ayenera kutenthedwa pa 1900 mpaka 1975°F [1040 mpaka 1080°C] ndipo azitenthedwa pa 1350 mpaka 1470°F [730 mpaka 800°C]

Mambale a Giredi 5, 9, 21, 21L, 22, 22L, ndi 91 oyitanidwa popanda kutenthedwa ndi tebulo pamwambapa, adzamalizidwa mukakhala kupsinjika kapena kupsinjika.
