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 |
21, 21L | 3.00 | 1.00 |
5 | 5.00 | 0.50 |
9 | 9.00 | 1.00 |
91 | 9.00 | 1.00 |
Ibipimo byerekanwe kuri ASTM A387 Amashanyarazi ya plaque ASTM
A20 / A20M: Ibisabwa muri rusange kubisahani byumuvuduko.
A370: Ikizamini cyerekana imiterere yubukorikori
A435 / A435M: Kugirango ugenzure neza-ultrasonic isuzuma ibyapa.
A577 / A577M: Kugirango ultrasonic angle beam isuzume ibyapa.
A578 / A578M: Kuburyo bugororotse UT isuzuma ryibyuma bizunguruka mubisabwa bidasanzwe.
A1017 / A1017M: Ibisobanuro byerekana amasahani yamashanyarazi yamashanyarazi, chromium-molybdenum-tungsten.
Ibisobanuro bya AWS
A5.5 / A5.5M: Amashanyarazi make ya electrode yo gukingira ibyuma arc gusudira.
A5.23 / A5.
A5.28 / A5.28M: Kuri gusudira gaze ikingiwe arc gusudira.
A5.29 / A5.29M: Kuri flux cored arc gusudira.
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, bigakurikirwa nubushyuhe, ubushyuhe buke bwubushyuhe bugomba kuba munsi yimbonerahamwe:
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 byateganijwe nta kuvura ubushyuhe ukoresheje imbonerahamwe iri hejuru, bizarangira haba mubibazo byoroheje cyangwa byifashe neza.
