Ifishi yatumijwe igomba kuba ikubiyemo ibintu 11 bikurikira:
1. Umubare (ibirenge, metero cyangwa umubare winkoni)
2. Izina ryibikoresho (umuyoboro utagira ibyuma)
3. Inzego (16 zose hamwe: P1, P2, P22, P11, P22, P91)
4. Uburyo bwo gukora (gushushanya bishyushye cyangwa gushushanya ubukonje)
5. Koresha kimwe mubisobanuro bikurikira: 1), NPS hamwe nuburinganire bwurukuta rwumubare wurutonde, 2), diameter yinyuma nubunini bwurukuta rwizina, 3), diameter yo hanze nuburebure bwurukuta ruto, 4), diameter yimbere nubunini bwurukuta, 5), diameter y'imbere hamwe n'uburebure bw'urukuta ntarengwa rwo gutumiza amabwiriza
6. Uburebure (bugabanijwemo uburebure bwagenwe n'uburebure butazwi)
7. Kurangiza gutunganya.
8. Ibisabwa byo gutoranya (umuvuduko wamazi no kwemerera gutandukana ibiro).
9. Raporo y'ibizamini bisabwa (reba A530).
10. Umubare usanzwe.11Ibisabwa byihariye cyangwa ibisabwa byose byiyongera.
Ibikoresho no gukora
1. Imiyoboro yicyuma irashobora gushyukwa cyangwa gukonjeshwa imbeho, kandi ikaba yarangije ubushyuhe bwa nyuma busabwa nibisanzwe.
2. Icyuma cya P2 na P12.Ibyiciro byombi byibyuma bigomba gukorwa hifashishijwe uburyo bwo gushonga ingano.Niba hari ibisabwa byihariye kubunini bwingano cyangwa inzira ya deoxidation, bigomba kumvikana nuwaguze nuwakoze ibyuma.
3. Kuvura ubushyuhe
1. Usibye ibyuma bya PSC, P23, P91, P92, P122 na P911 kandi nkuko byavuzwe, ibyiciro byose byimiyoboro yizina bizashyuha kandi bitangwe muburyo bwuzuye, isothermal annealed cyangwa bisanzwe kandi bisanzwe.Niba itanzwe muburyo busanzwe kandi bushyushye, ubushyuhe bwo hasi bwubushyuhe bwa P5, P5B, P9, P21 na P22 bugomba kuba 675 ° C.Ubushyuhe bwo hasi bwubushyuhe bwa P1, P2, P11, P12 na P15 bugomba kuba 650 ℃
2. Ubushyuhe bwa nyuma bwo kuvura ibyuma bya P92 na P911 bigomba kuba bisanzwe byibuze 1040 ℃ no gushyuha byibuze 730 ℃.
