347 Ibha Yensimbi Engagqwali

I-UNS S34700 (Grade 347)

Ibha yensimbi engagqwali engu-347, eyaziwa nangokuthi i-UNS S34700 kanye ne-Grade 347, iyinsimbi engagqwali ye-austenitic eyenziwe nge-.08% carbon maximum, 17% kuya ku-19% chromium, 2% manganese esiphezulu, 9% kuya ku-13% nickel, 1% i-silicon ephezulu , iminonjana ye-phosphorus nesibabule, i-1% ubuncane kuya ku-10% i-columbium ephezulu ne-tantalum enebhalansi yensimbi. IBanga lama-347 linenzuzo ensizakalweni yokushisa okuphezulu ngenxa yezakhiwo zalo ezinhle zemishini; futhi inokumelana okuhle kakhulu nokugqwala kwe-intergranular kulandela ukuchayeka emazingeni okushisa ebangeni lemvula ye-chromium carbide ukusuka ku-800 ° kuya ku-1500 ° F. Iyafana neBanga 321 ngokuphathelene nokugqwala kwe-intergranular okutholakala ngokusebenzisa i-columbium njengento yokuzinzisa wandise lesi sici. IBanga 347 alikwazi ukwenziwa lukhuni ngokwelashwa ngokushisa, kodwa izakhiwo eziphakeme zingatholakala ngokunciphisa amakhaza.

Izimboni ezisebenzisa i-347 zifaka:

• I-Aerospace
• Ivalvu

Imikhiqizo eyakhiwe ngokwengxenye noma ngokuphelele ye-347 ihlanganisa:

• Izindandatho zokuqoqa izindiza
• Imishini yokukhiqiza amakhemikhali
• Izingxenye zenjini
• Exhaust manifolds
• Ama-gaskets okushisa aphezulu kanye namajoyinti okwandisa
• Izingxenye zenjini yerokhethi
