Intangiriro kuri
304 ibyuma nicyuma gisanzwe kidafite ingese, kizwi kandi nka 18/8 ibyuma bitagira ingese mu nganda.Kurwanya kwangirika kwayo kurenza ibyuma 430 bidafite ingese, ariko igiciro gihendutse kuruta 316 ibyuma bitagira umuyonga, bityo rero bikoreshwa cyane mubuzima, nka: bimwe mubikoresho byo mu rwego rwohejuru bidafite ibyuma byo kumeza, ibikoresho byo hanze bidafite ibyuma, nibindi Nubwo ibyuma 304 aribyo bikunze kugaragara cyane mu Bushinwa, izina "304 ibyuma" rikomoka muri Amerika.Abantu benshi batekereza ko ibyuma 304 nizina ryicyitegererezo mubuyapani, ariko tuvugishije ukuri, izina ryicyuma 304 mubuyapani ni "SUS304".304 ibyuma ni ubwoko bwibyuma bitagira umwanda, bikoreshwa cyane mugukora ibikoresho nibice bisaba imikorere myiza yuzuye (kurwanya ruswa no guhinduka).Kugirango ukomeze kurwanya ruswa igaragara mubyuma bidafite ingese, ibyuma bigomba kuba birimo chromium irenga 16% nibirimo nikel irenga 8%.304 ibyuma bidafite ingese ni ikirango cyibyuma bikozwe muburyo bwa ASTM bwabanyamerika.304 ihwanye na 0Cr18Ni9 ibyuma bitagira umwanda mugihugu cyacu.

Igipimo cya
Kuri 304 ibyuma ni ikintu cyingenzi cyane, kigena mu buryo butaziguye kurwanya ruswa, ariko kandi kigena agaciro kacyo.Ibyingenzi byingenzi muri 304 ibyuma ni Ni na Cr, ariko ntibigarukira kuri ibi bintu byombi.Ibisabwa byihariye bisobanurwa nibipimo byibicuruzwa.Urubanza rusanzwe rwinganda rwemeza ko mugihe cyose ibirimo Ni birenze 8%, Ibirimo Cr birenze 18%, birashobora gufatwa nkibyuma 304.Niyo mpamvu inganda zita ubu bwoko bwibyuma 18/8 ibyuma.Mubyukuri, ibipimo ngenderwaho bijyanye nibicuruzwa 304 bifite ingingo zisobanutse neza, kandi ibipimo byibicuruzwa kumiterere itandukanye yicyuma kandi hari itandukaniro.
