Icyuma kitagira ikinamico ni alloye ndende ibyuma bishobora kurwanya ruswa mu kirere cyangwa imiti. Icyuma kitagira ingaruka gifite ubuso bwiza kandi bwiza bwo kurwanya ibicuruzwa. Ntabwo ikeneye kuvurwa no kuvura hejuru nko kwibisha, ariko igira imitungo isanzwe yicyuma. Nubwoko bwibyuma bikoreshwa mubice byinshi kandi mubisanzwe bita ibyuma bitagira ingaruka. Umukozi uhagarariye arimo ibyuma 13 bya chromium, imyaka 18-8 chromium-nikel nandi makosa yo hejuru.

Ukurikije ibyuma bya crablipelography, kubera ko ibyuma bitagira ingano irimo chromium, film yoroheje ya chromium yakozwe hejuru. Iyi firime itandukanya ogisijeni itera ibyuma kandi igira uruhare runini.
Kugirango ukomeze kugabanuka kwangiza ibyuma bidafite ikibazo, ibyuma bigomba kubamo chromium irenze 12%.
304 nintego rusange-idafite intego ikoreshwa cyane mugutanga ibikoresho nibice bisaba imikorere myiza (ibyuma bya ruswa nicyiciro cyica cyicaraga gakongizo zakozwe na ASTM. 304 bihwanye nigihugu cyanjye 0cr19NI9 (0CR18NI9) Icyuma. 304 ikubiyemo 19% chromium na 9% nikel.
304 nicyo cyakoreshejwe cyane cyane ibyuma no kurwanya ubushyuhe. Ikoreshwa mu bikoresho byo gutanga umusaruro, ibikoresho bya shimi, ingufu za kirimbuzi, n'ibindi.
