Ubwoko 347H ni karubone ndende ya austenitis chromium idafite ibyuma. Byabonetse mubisabwa bisaba ubushyuhe bwo hejuru, ibindi bintu byingenzi bishushanya birimo:
- Kurwanya kimwe no kurinda ruswa nka Alloy 304
- Ikoreshwa mubikoresho biremereye byo gusudira mugihe annealing bidashoboka
- Kurwanya okiside nziza, kuringaniza nibindi byuma byinshi bya austenitis
- Carbone yo hejuru itanga ubushyuhe bwiza bwo hejuru
Bitewe nubwoko 347H budasanzwe bukoreshwa muburyo butandukanye bukoreshwa muruganda runini rukomeye:
- Imiyoboro yo gutekesha hamwe
- Imiyoboro ya peteroli na gaze
- Imirasire yumucyo
- Imiyoboro yumuvuduko mwinshi
- Ubushyuhe bwo guhinduranya
- Amashanyarazi
- Ibikoresho bikomeye byo gusudira
- Indege isohora indege hamwe nimpeta zo gukusanya
Hamwe nurwego rwohejuru rwa karubone noneho Ubwoko bwa 347 busanzwe, Ubwoko 347H ibyuma bidafite ingese bifite imiti idasanzwe ikubiyemo ibi bikurikira:
- Kuringaniza
- Cr 17-20%
- Ni 9-13%
- C 0.04-0.08%
- Mn 0.5-2.0%
- S 0,30% max
- Si 0,75% max
- P 0.03% max
