Ubwoko 321 Icyuma kitagira umuyonga nicyuma cya austenitis. Ifite imico myinshi yubwoko 304, usibye urwego rwo hejuru rwa titanium na karubone. Ubwoko 321 butanga abahimbyi b'ibyuma birwanya ruswa kandi irwanya okiside, hamwe n'ubukomere buhebuje ndetse kugeza no ku bushyuhe bwa kirogenike. Ibindi biranga Ubwoko 321 Ibyuma bitagira umuyonga birimo:
- Gukora neza no gusudira
- Ikora neza kugeza kuri 900 ° C.
- Ntabwo ari ugukoresha imitako
Bitewe ninyungu nubushobozi bwinshi, Ubwoko 321 bukoreshwa muburyo butandukanye burimo:
- Igifuniko
- Ibikoresho byo hejuru cyane
- Ibikoresho byo gutunganya imiti
- Sisitemu yo gusohora ibinyabiziga
- Firewall
- Amabati
- Indege isohora ibirindiro hamwe na manifold
- Amashanyarazi
- Ibikoresho byo gutunganya gaz na peteroli
Ubwoko 321 bufite imiterere yihariye yimiti ikubiyemo:
- Cr 17-19%
- Ni 9-12%
- Si 0,75%
- Fe 0.08%
- Ti 0,70%
- P .040%
- S .030%
Turashobora gutanga ibigo hamwe nubwoko 321 mubunini butandukanye, nka plaque, urupapuro, na coil. Ubwoko 321 bwose buboneka binyuze kuri cepheus idafite ibyuma Ibyuma bihura cyangwa birenga AMS 5510 na ASTM A240.
