Ni gute igiciro cy’ibikoresho by’icyuma gikozwe mu buryo bwa 430 Stainless Steel Grade kidahinduka ugereranyije n’icya 304 na 316 gihagaze neza?
Ingano ya 430 irahamye cyane bitewe n’uko nikeli iri hasi ndetse n’imiterere ya chromium gusa. Ingano ya 430 ishyigikira ikiguzi cya 15% kugeza kuri 25% kuri buri kg ugereranije n’icyiciro cya 304 n’ikiguzi cya 25% kugeza kuri 35% kuri buri kg ugereranije n’icyiciro cya 316.
Ni ubuhe bunini busanzwe bw'icyuma kitagira umugese cya 430 mu bikoresho byo mu rugo?
Igipimo gito (milimetero 0.3 kugeza kuri 0.5) ni icy'inyuma y'icyuma gikaraba amasahani n'akayunguruzo k'imashini. Igipimo giciriritse (milimetero 0.5 kugeza kuri 1.0) ni icy'ingoboka y'imbere y'imashini imesa. Igipimo gisanzwe (milimetero 1.0 kugeza kuri 2.0) ni icy'igikoni n'inyuma y'ifuru.
Ni ubuhe buryo busanzwe bwo kurangiza icyuma cya 430 cya stainless steel mu bikoresho byo mu rugo?
2B ni iy'imbere. BA ni iy'inyuma. No.4 ni iy'igikoni n'urugi. No.8 ni iy'ibikoresho byo mu rugo byo hanze bigezweho.
Ni ikihe giciro cya nikeli cya LME ku giciro cya 430 ugereranije n'icyiciro cya 304 na 316L?
Ingano ya 430 ifite igiciro cya nickel cya 0% cya LME. Ingano ya 304 ifite igiciro cya nickel cya 8% cya LME. Ingano ya 316L ifite igiciro cya nickel cya 10% cya LME. Ingano ya 430 ishyigikira ibiciro by'ibiciro biteganyijwe mu mezi 12 y'umusaruro.
Ni iyihe gabanuka risanzwe rya TCO kuva ku rwego rwa 430 ugereranyije n'urwego rwa 304 ku bikoresho byo mu rugo?
Ingano ya 430 ubusanzwe ishyigikira TCO yose iri hasi ya 18% kugeza kuri 25% mu gihe cy'amezi 12 yo gukora kuri buri giciro gito cya buri kilo n'igiciro gito cya lisansi ugereranije n'icyiciro cya 304.
Ibyerekeye Umwanditsi
Bwana Chen — Umuyobozi wa Tekiniki, w’inzobere mu gutoranya ibikoresho by’icyuma kitagira umugese, gukoresha ibikoresho bikonjesha, no gutanga ibisubizo ku bikoresho by’inganda.
