Hariho ibintu bitatu by'ingenzi bigira ingaruka ku kwangirika kw'icyuma hepfo:
1.Ibiri mu bintu bivangavanze, muri rusange, ibikubiye muri chromium mu byuma 10.5% ntabwo bizangirika byoroshye.
Iyo hejuru ya chromium na nikel, niko birwanya ruswa.Kurugero,
ibirimo nikel mubikoresho 304 ni 8-10%, naho chromium igera kuri 18-20%.
Ibyuma nkibi bidafite ingese ntibishobora kubora mubihe bisanzwe.
| Icyiciro | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Bisanzwe |
| 1070 | 0.2 | 0.25 | 0.04 | 0.03 | 0.03 | / | 0.04 | 0.03 | EN / ASTM |
| 3003 | 0.6 | 0.7 | 0.05-0.2 | 1.0-1.5 | / | / | 0.10 | / | EN / ASTM |
| 5052 | 0.25 | 0.40 | 0.10 | 0.10 | 2.2-2.8 | 0.15-0.35 | 0.10 | 0.10 | EN / ASTM |
2.Uburyo bwo gushongesha uruganda bizagira ingaruka no kurwanya ruswa yibyuma.
Uruganda runini rudafite ibyuma bifite tekinoroji nziza yo gushonga,
ibikoresho bigezweho hamwe nikoranabuhanga rigezweho birashobora kwemeza kugenzura ibintu bivangavanze,
kuvanaho umwanda, no kugenzura ubushyuhe bukonje bwa bilet,
ubwiza bwibicuruzwa rero burahamye kandi bwizewe, ubwiza bwimbere nibyiza, kandi ntabwo byoroshye kubora.Ahubwo,
insyo ntoya ntoya ifite ibikoresho nubuhanga byasubiye inyuma.Mugihe cyo gushonga,
umwanda ntushobora gukurwaho, nibicuruzwa byakozwe byanze bikunze byangirika.
3.Ibidukikije byo hanze, ibidukikije byumye kandi bihumeka ntabwo byoroshye kubora.Ariko,
ubuhehere bwo mu kirere buri hejuru, ibihe by'imvura bikomeza, cyangwa ibidukikije bifite pH nyinshi mu kirere byoroshye kubora.
304 ibyuma bidafite ingese, niba ibidukikije bidukikije ari bibi cyane, bizangirika.
Abakiriya benshi bajya ku isoko kugura ibyuma bitagira umwanda bakazana na magneti nto.
Hatabayeho magnetisme, ntihazabaho ingese.Mubyukuri, ibi ni imyumvire itari yo.
Icyuma kitari magnetiki kitagira ibyuma kigenwa nuburyo bwimiterere.
Mugihe cyo gukomera, ibyuma bishongeshejwe bizakora "ferrite", "austenite",
"Martensite" hamwe nibindi byuma bidafite ingese hamwe nuburyo butandukanye.Muri bo,
"Ferrite" "Umubiri" na "Martensitike" ibyuma bitagira umwanda byose ni magnetique.
"Austenitike" ibyuma bidafite ingese bifite imiterere rusange yubukanishi,
imikorere yimikorere no gusudira, ariko mubijyanye gusa no kurwanya ruswa,
magnetiki "ferritic" ibyuma bidafite ingese birakomeye kuruta "austenitis" ibyuma bitagira umwanda.
Kugeza ubu, ibyo bita 200 serie na 300 serie idafite ibyuma hamwe na hejuru
ibirungo bya manganese hamwe na nikel nkeya ku isoko ntabwo ari magnetique,
ariko imikorere yabo iratandukanye cyane niyya 304 ifite nikel nyinshi.Ahubwo,
304 yararambuwe, irashyirwa, irasukurwa, kandi iraterwa.Kuvura inzira nabyo bizaba micro-magnetique,
rero ni ukutumva kandi siyansi gucira urubanza ubuziranenge bwibyuma bidafite ingese nta magnetisme.
