Kuvanga Ibirimo bya Chrome Moly

Chrome moly plaque munsi ya ASTM A387 mubyiciro bya seriveri ifite ibintu bitandukanye bivanze nkuko biri munsi, amanota yo gukoresha ni Gr 11, 22, 5, 9 na 91.

Usibye 21L, 22L na 91, buri cyiciro kiraboneka mubyiciro bibiri byingufu zingana nkuko byasobanuwe mumeza asabwa.Icyiciro cya 21L na 22L gifite icyiciro cya 1 gusa, naho icyiciro cya 91 gifite Class2 gusa.

Icyiciro	Nominal Chromium Ibirimo,%	Nominal Molybdenum Ibirimo,%
2	0.50	0.50
12	1.00	0.50
11	1.25	0.50
22, 22L	2.25	1.00

Kuvura Ubushyuhe kuri A387 Chrom Moly Alloy Icyuma

Icyuma cya Chrome moly alloy icyuma munsi ya ASTM A387 kigomba kwicwa ibyuma, hamwe no kuvurwa nubushyuhe haba muburyo bwa annealing, normarlizing and tempering.Cyangwa mugihe byumvikanyweho nabaguzi, gukonjesha byihuse biturutse ku bushyuhe bukabije bwo guhumeka ikirere cyangwa kuzimya amazi, hanyuma bigakurikirwa nubushyuhe, ubushyuhe buke bwubushyuhe bugomba kuba munsi yimeza:

Icyiciro	Ubushyuhe, ° F [° C]
2, 12 na 11	1150 [620]
22, 22L, 21, 21L na 9	1250 [675]
5	1300 [705]

Icyiciro cya 91 cyuma cyuma kigomba gushyukwa nubushyuhe nubushyuhe cyangwa gukonjeshwa byihuse no guturika ikirere cyangwa kuzimya amazi, hanyuma bigakurikirwa nubushyuhe.Icyapa cyo mu cyiciro cya 91 kigomba guhagarikwa kuri 1900 kugeza 1975 ° F [1040 kugeza 1080 ° C] kandi kigashyuha kuri 1350 kugeza 1470 ° F [730 kugeza 800 ° C]

Icyiciro cya 5, 9, 21, 21L, 22, 22L, na 91 byategetswe nta kuvura ubushyuhe ukoresheje imbonerahamwe iri hejuru, bizarangira haba mubibazo byoroheje cyangwa byifashe nabi.
