SHARAXA
Nooca 347/347H birta aan lahayn waa darajada austenitic ee birta chromium, kaas oo ka kooban kolumbium oo ah curiye xasilin ah. Tantalum sidoo kale waxaa lagu dari karaa si loo gaaro xasilinta. Tani waxay meesha ka saaraysaa roobabka carbide, iyo sidoo kale daxalka intergranular ee tuubooyinka birta. Nooca 347 / 347H tuubooyinka birta aan fiicnayn waxay bixiyaan guryaha dillaaca iyo walbahaarka sare marka loo eego fasalka 304 iyo 304L. Tani waxay ka dhigaysaa inay ku habboon yihiin muujinta dareenka iyo daxalka intergranular. Intaa waxaa dheer, ku darida kolumbium waxay u oggolaaneysaa 347 tuubooyinka inay yeeshaan iska caabin aad u wanaagsan, xitaa ka sarreeya tan 321 tuubooyinka birta ah. Si kastaba ha ahaatee, birta 347H waa kaarboonka sare ee beddelka ah ee heerka tuubooyinka birta aan fiicnayn
347 / 347H HANTIDA TUBE-GA AAN XANUUNKA LAHEYN
Kuwa soo socdaa waa sifooyinka 347/347H tuubooyinka birta aan fiicnayn ee ay bixiso Arch City Steel & Alloy:
Iska caabinta daxalka:
- Waxay muujisaa iska caabbinta oksaydhka oo la mid ah birta kale ee austenitic-ka ah
- Loo door biday in ka badan fasalka 321 ee aqueous iyo meelaha kale ee heerkulka hooseeya
- Heerkul sare oo ka wanaagsan 304 ama 304L
- Iska caabbinta wanaagsan ee dareenka jawiga heerkulka sare
- Ku habboon qalabka alxanka culus ee aan la daabi karin
- Loo isticmaalo qalabka ku shaqeeya inta u dhaxaysa 800 ilaa 150F (427 TO 816°C)
Weldability:
-
347 / 347H tuubooyinka birta ah ee aan fiicnayn waxaa loo tixgeliyaa inay yihiin kuwa ugu alxanka badan dhammaan tuubooyinka birta ee heerka sare ah
-
Waxaa lagu alxan karaa dhammaan hababka ganacsiga
Daawaynta Kulaylka:
-
347/347H Tubooyinka birta aan fiicnayn iyo tuubooyinka waxay bixiyaan heerkul heerkul ah 1800 ilaa 2000 ° F
-
Waxay noqon karaan nafis walbahaarka oo la tirtiro iyada oo aan wax khatar ah u iman daxalka intergranular ee xiga gudaha qiyaasta roobabka carbide ee 800 ilaa 1500 ° F
-
Laguma adkeyn karo daawaynta kulaylka
Codsiyada:
Tuubooyinka 347/347H ayaa inta badan loo isticmaalaa samaynta qalabka ay tahay in loo isticmaalo xaaladaha daxalka daran. Sidoo kale, waxaa caadi ahaan loo isticmaalaa warshadaha sifaynta batroolka. Codsiyada waaweyn waxaa ka mid ah:
- Hababka kiimikada heerkulka sare
- Tuubooyinka kulaylka
- Dhuumaha uumiga cadaadiska sare
- Uumi heerkul sarreeya iyo tuubooyinka kululeeyaha
- Nidaamyada qiiqa culeyska culus
- Kuleyliyaha sare ee shucaaca
- Tuubooyinka sifaynta guud
