304 umuyoboro wibyuma udafite ibyuma byuzuye
Uburyo busanzwe bwo gushira akamenyetso ku isoko burimo 06cr19ni10 na SUS304, muri zo 06cr19ni10 muri rusange zerekeza ku musaruro usanzwe w’igihugu, 304 muri rusange zerekeza ku musaruro usanzwe wa ASTM, naho SUS 304 yerekeza ku bicuruzwa bisanzwe by’Ubuyapani.
304 nicyuma rusange kitagira umwanda, gikoreshwa cyane mugukora ibikoresho nibice bisaba imikorere myiza yuzuye (kurwanya ruswa no guhinduka). Kugirango ukomeze kwangirika kwangirika kwibyuma bitagira umwanda, ibyuma bigomba kuba birimo chromium irenga 18% na nikel irenga 8%. 304 ibyuma bidafite ingese ni ikirango cyibyuma bidafite ingero zakozwe ukurikije ibipimo bya Amerika ASTM.

Ku byuma 304 bidafite ingese, Ni element mu bigize ni ngombwa cyane, igena mu buryo butaziguye kurwanya ruswa ndetse n’agaciro ka 304 ibyuma bitagira umwanda.
Ibintu byingenzi muri 304 ni Ni na Cr, ariko ntibigarukira kuri ibi bintu byombi. Ibisabwa byihariye bisobanurwa mubicuruzwa bisanzwe. Ukurikije imyanzuro isanzwe mu nganda, ibyuma 304 bidafite ingese birashobora gufatwa igihe cyose ibirimo Ni birenze 8% naho Cr ikarenga 18%. Niyo mpanvu ubu bwoko bwibyuma bitagira ibyuma byitwa 18/8 ibyuma bidafite inganda. Mubyukuri, ibipimo ngenderwaho bijyanye nibicuruzwa bifite ingingo zisobanutse neza kuri 304, kandi ibipimo byibicuruzwa bifite aho bihuriye nuburyo butandukanye bwibyuma. Hano hari ibicuruzwa bisanzwe hamwe nibizamini.
Kugirango umenye niba ibikoresho ari 304 ibyuma bidafite ingese, bigomba kuba byujuje ibisabwa bya buri kintu mubicuruzwa. Igihe cyose umuntu atujuje ibisabwa, ntishobora kwitwa 304 ibyuma bitagira umwanda.

Ibipimo bine byavuzwe haruguru ni bike mubisanzwe. Mubyukuri, ibirenze aya mahame avugwa muri ASTM na JIS. Mubyukuri, buri gipimo gifite ibisabwa bitandukanye kuri 304, niba rero ushaka kumenya niba ibikoresho ari 304, imvugo nyayo igomba kuba niba yujuje ibisabwa 304 mubicuruzwa.
