430 ibyuma bitagira umuyonga byoroshye, umunaniro wubushyuhe, aside, gaze ya alkaline, igisubizo nibindi birwanya ruswa.Ububasha bukabije, ubukana nimbaraga za mashini;201 Umuyoboro w'icyuma udafite umwanda ufite ibiranga aside irwanya, kurwanya alkali, ubucucike bukabije butagira pinhole, nibindi, ni ugukora ibintu bitandukanye byisaha, igipfundikizo cyo hepfo hamwe nibindi bikoresho byujuje ubuziranenge.201 Imiyoboro idafite ibyuma irashobora gukoreshwa mu miyoboro ishushanya, imiyoboro yinganda, hamwe nibicuruzwa bishushanyije.
430 ibyuma bitagira umuyonga na 201 itandukaniro ryicyuma
430 ibyuma bitagira umuyonga ni martensitike idafite ibyuma, ibyuma bya martensitike bitagira ibyuma hamwe nicyuma gisanzwe cya alloy ibyuma bifite imiterere imwe yo gukomera binyuze mu kuzimya, martensitike ya chromium idafite ibyuma mu kuzimya - ibihe byubushyuhe, kongera ibikubiye muri chromium bishobora kongera ibintu bya ferritic, bityo bikagabanya ubukana kandi imbaraga.Mugihe cya annealing, ubukana bwa karubone ya martensitike ya chromium idafite ibyuma byiyongera hamwe no kwiyongera kwa chromium, mugihe kurambura kugabanuka gato.Ukurikije ibintu bimwe na bimwe bya chromium, kwiyongera kwa karubone bizongera ubukana bwibyuma nyuma yo kuzimya, kandi plastike izagabanuka.
Nyuma yo kuzimya ubushyuhe buke, ingaruka zinyongera za molybdenum ziragaragara cyane.Intego nyamukuru yo kongeramo molybdenum nukuzamura imbaraga, gukomera ningaruka zo gukomera kwicyuma.Muri martensitike chromium-nikel ibyuma bitagira umuyonga, ibirimo δ ferrite mubyuma birashobora kugabanywa na nikel runaka, kugirango ibyuma bibone agaciro gakomeye.
210 ibyuma bidafite ingese ni chromium-nikel austenitis ibyuma bitagira umuyonga, ibyuma bya austenitike bidafite ibyuma bya magnetique kandi bifite ubukana bwinshi na plastike, ariko imbaraga ni nke, ntibishoboka gukomera binyuze mumihindagurikire yicyiciro, gusa binyuze mubukonje bukora kugirango ushimangire.Niba S, Ca, Se, Te nibindi bintu byongeweho, bifite imashini nziza.Niba irimo Mo, Cu nibindi bintu, irashobora kandi kurwanya ruswa ya acide sulfurike, aside fosifori, aside aside, aside acike, urea nibindi.Niba karubone yibyuma bitarenze 0.03% cyangwa irimo Ti, Ni, irashobora kunoza cyane kurwanya kwangirika kwimitsi.Silicon yo hejuru austenitike idafite ibyuma bya acide nitricike irwanya ruswa.Kuberako ibyuma bya austenitis bidafite ibyuma byuzuye kandi byiza byuzuye, byakoreshejwe cyane mubice byose.
Muri make, ibyuma 430 bidafite ingese na 201 ibyuma bitagira umwanda bifite inyungu ninyungu zabyo, 430 irwanya aside ibyuma bitagira umwanda, kurwanya alkali, agaciro gakomeye birakomeye, plastike 210 idafite ibyuma nibyiza, ifite imikorere yuzuye, irashobora gukwiranye nibikenewe, hitamo ubwoko bukwiye bwibyuma.
