Mu bwoko butandukanye bw'icyuma, amanota 304, 304l, na 304h bakunze gukoreshwa. Mugihe bashobora kusa, buri cyiciro gifite imitungo yihariye.
Amanota304 ibyuma bitagira inganonicyo gikoreshwa cyane kandi gisanzwe cyimirongo 300 idahwitse. Irimo chromium 18-20% na 8-10.5% Nikel, hamwe na karubone nto, Mangase, na Silicon. Iki cyiciro gifite ihohoterwa ryiza ryo kurwanya ibicuruzwa byiza. Bikoreshwa kenshi mubisabwa nkibikoresho byo mu gikoni, gutunganya ibiryo, no gushushanya.
304L umuyoboro w'icyumani ibyuma bike bya karubone itandukanya icyiciro cya 304, hamwe na karubone ntarengwa ya 0.03%. Ibirimo bike bya karubone bifasha kugabanya imvura ya carbide mugihe cyo gusudira, bigatuma bikwiranye no gusudira. Ibirimo byo hasi bya karubone nabyo bigabanya ibyago byo gukangurira, ni ugushiraho ibikaro bya chromium ku mbibi z'ingano, zishobora kuganisha ku gakondo. 304l ikunze gukoreshwa mugutanga isuku, hamwe nibidukikije aho ibyago byo kugaburira ari impungenge, nkibikoresho byo gutunganya imiti nibikoresho bya farumasi.
304h ibyumani verisiyo yo hejuru ya karubone yo mu cyiciro cya 304, hamwe n'ibirimo bya karubone kuva kuri 0.04-0.10%. Ibirimo byinshi bya karubone bitanga imbaraga nziza cyane yubushyuhe na creep. Ibi bituma 304h ibereye gusaba ubushyuhe bwinshi, nkigikoresho cyumuvuduko wigitutu, guhanahana ubushyuhe, hamwe nubwato bwinganda. Ariko, ibintu byinshi bya karubone nabyo bituma 304h yarushagaho gukangurira gukangurira no guhagarika ibicuruzwa byinshi, cyane cyane muburyo bwo gusudira.
Muri make, itandukaniro nyamukuru riri hagati yizi manota nibirimo karubone hamwe ningaruka zo gusudira no gutanga ubushyuhe bwo hejuru. Icyiciro cya 304 nintego ikoreshwa cyane kandi rusange, mugihe 304l nizo zahisemo gusudira porogaramu nibidukikije aho kunyeganyega ari impungenge. 304H ifite ibirimo bya karubone yo hejuru kandi bikwiranye nubushyuhe bwo hejuru cyane, ariko kongerwa no gukangurira no gukandamira no kwisuzumisha bisaba kwitabwaho neza. Mugihe uhisemo hagati yizi manota, ni ngombwa gusuzuma ibisabwa byihariye byo gusaba, harimo n'ibidukikije, ubushyuhe, no gutangara.
