Waa maxay faraqa u dhexeeya 17-4PH iyo Biraha kale ee Roob-adag (PH)?

Hordhac

Biraha aan miridhku adkaynayn ee roobka (biraha PH) waa nooc ka mid ah biraha u adkaysta daxalka kuwaas oo isku daraya xoogga biraha martensitic iyo austenitic oo leh iska caabin aad u fiican oo daxalka ah. Kuwaas waxaa ka mid ah,Bir aan miridh lahayn oo 17-4PH ahWaxaa la dhihi karaa waa kan ugu isticmaalka badan sababtoo ah sifooyinkiisa farsamo ee gaarka ah iyo fududaynta farsamaynta. Laakiin sidee ayay ula barbar dhigtaa darajooyinka kale ee PH sida 15-5PH, 13-8Mo, 17-7PH, iyo Custom 465? Maqaalkani wuxuu si qoto dheer u eegayaa kala duwanaanshaha qaab-dhismeedka, daaweynta kulaylka, sifooyinka farsamada, iska caabbinta daxalka, iyo codsiyada.

Dulmar guud oo ku saabsan Biraha aan lahayn ee Roobka oo Adkaanaya

Biraha adag ee roobka waxay xooggooda ka helaan sameynta roobab yaryar oo ku jira shaxda birta inta lagu jiro daaweynta kulaylka gabowga. Birahaan waxaa loo qaybiyaa saddex qaybood oo waaweyn:

1. Biraha PH ee Martensitic(tusaale ahaan,17-4PH, 15-5PH)
2. Biraha PH ee semi-austenitic(tusaale ahaan, 17-7PH)
3. Biraha PH ee Austenitic(tusaale ahaan, A286)

Qayb kastaa waxay bixisaa isku-darka gaarka ah ee hantida loogu talagalay baahiyaha warshadaha gaarka ah.

Gunaanad

In kasta oo 17-4PH ay tahay birta aan miridhku lahayn ee PH ee loogu talagalay codsiyada guud ee badan, haddana heer kasta oo PH ah oo beddel ah wuxuu leeyahay faa'iidooyin gaar ah oo ka dhigaya mid si fiican ugu habboon shuruudo gaar ah. Fahmidda kala duwanaanshaha u dhexeeya alwaaxyadan waxay u suurtagelinaysaa injineerada agabka iyo iibsadayaasha inay sameeyaan go'aanno xog ogaal ah oo ku salaysan xoogga, adkeysiga, iska caabbinta daxalka, iyo kharashka.
