Mu moko atandukanye y'ibyuma bitarangirika, ibipimo bya 304, 304L, na 304H bikunze gukoreshwa. Nubwo bishobora gusa, buri gipimo gifite imiterere yacyo n'uburyo gikoreshwa.
IcyiciroIbyuma 304 bita icyuma gifunganyeni cyo cyuma gikoreshwa cyane kandi gishobora gukoreshwa mu buryo butandukanye mu byuma 300 bita stainless. Gifite chromium 18-20% na nikeli 8-10.5%, hamwe n'ingano nto ya karuboni, manganese, na silikoni. Iki gipimo gifite ubushobozi bwo kurwanya ingese kandi gishobora gushingwa neza. Gikunze gukoreshwa mu bikoresho nko mu gikoni, mu gutunganya ibiribwa, no mu mitako y'inyubako.
Umuyoboro w'icyuma kitagira umwanda wa 304Lni ubwoko bw'imiyoboro y'icyuma ifite karuboni nkeya ya 304, ifite karuboni ntarengwa ya 0.03%. Ubu bwoko bw'ikaruboni nkeya bufasha kugabanya imvura ya karuboni mu gihe cyo gusudira, bigatuma ikoreshwa mu gusudira. Ubunini bwa karuboni nkeya bugabanya kandi ibyago byo kwangirika, ari byo kurema karuboni za chromium ku mbibi z'ingano, bishobora gutera ingese hagati y'uduce duto. 304L ikunze gukoreshwa mu gusudira, ndetse no mu bidukikije aho ibyago byo kwangirika ari ikibazo, nko gutunganya imiti n'ibikoresho by'imiti.
Icyuma kitagira umwanda cya 304Hni verisiyo ya karuboni iri hejuru ya 304, ifite ingano ya karuboni iri hagati ya 0.04 na 0.10%. Iyo karuboni iri hejuru itanga imbaraga nziza z'ubushyuhe bwinshi no kudacika intege. Ibi bituma 304H ikoreshwa mu bushyuhe bwinshi, nko mu byuma bishyushya, mu byuma bihindura ubushyuhe, no mu byuma bishyushya mu nganda. Ariko, iyo karuboni iri hejuru inatuma 304H irushaho kwangirika no kwangirika hagati y’udusimba, cyane cyane mu byuma bisudira.
Muri make, itandukaniro rikomeye riri hagati y’ibi byiciro ni ingano ya karuboni ikoreshwamo n’ingaruka zayo ku gusudira no gukoresha ubushyuhe bwinshi. Icyiciro cya 304 ni cyo gikoreshwa cyane kandi gikoreshwa muri rusange, mu gihe 304L ari yo ikoreshwa cyane mu gusudira no mu bidukikije aho ingese ari ikibazo. 304H ifite ingano ya karuboni nyinshi kandi ikwiriye gukoreshwa mu bushyuhe bwinshi, ariko ishobora kwangizwa no gukururwa no kwangirika hagati y’uduce duto bisaba kwitabwaho cyane. Mu guhitamo hagati y’ibi byiciro, ni ngombwa gusuzuma ibisabwa byihariye by’ikoreshwa, harimo ibidukikije bikorerwamo, ubushyuhe, n’ibikenewe mu gusudira.
