Abantu bakunze gutekereza ko magneti zifata icyuma kitagira umugese kugira ngo barebe ubuziranenge bwacyo n'ukuri kwacyo. Iyo kidakuruye ibintu bitari magneti, gifatwa nk'ikintu cyiza kandi cy'ukuri; iyo gikuruye magneti, gifatwa nk'ikinyoma. Mu by'ukuri, ubu ni uburyo bwo kumenya ibintu bushingiye ku ruhande rumwe gusa, budahuje n'ukuri kandi butari bwo.
Hari ubwoko bwinshi bw'ibyuma bitarangirika, bushobora kugabanywamo ibyiciro byinshi hakurikijwe imiterere yabyo ku bushyuhe bw'icyumba:
1. Ubwoko bwa Austenitike: nka 304, 321, 316, 310, n'ibindi;
2. Ubwoko bwa Martensite cyangwa ferrite: nka 430, 420, 410, n'ibindi;
Austenite ntabwo ari magnetic cyangwa ngo ibe ya magnetic idakomeye, mu gihe martensite cyangwa ferrite ari magnetic.
Ibyinshi mu byuma bitagira umugese bikunze gukoreshwa mu mpapuro z'imitako ni ibikoresho bya austenitic 304. Muri rusange, ntabwo ari rukuruzi cyangwa ngo ibe ikomeye cyane. Ariko, bitewe n'ihindagurika ry'imiterere y'ibinyabutabire bitewe n'ishongeshwa cyangwa uburyo butandukanye bwo gutunganya, rukuruzi na yo ishobora kubaho, ariko ibi ntibishobora gufatwa nk'ibihimbano cyangwa ibidafite ishingiro, ni iyihe mpamvu?
Nkuko byavuzwe haruguru, austenite ntabwo ari rukuruzi cyangwa ifite imbaraga nke za rukuruzi, mu gihe martensite cyangwa ferrite ari rukuruzi. Bitewe no gutandukanya ibice cyangwa uburyo butari bwiza bwo gushyushya mu gihe cyo gushongesha, hazabaho ingano nto ya martensite cyangwa ferrite mu cyuma cya austenitic 304. Muri ubwo buryo, icyuma cya 304 kizagira imbaraga nke za rukuruzi.
Byongeye kandi, nyuma yo gukoresha icyuma gikonjesha 304, imiterere y’ikigo izahinduka na martensite. Uko urwego rw’ihinduka ry’imikorere y’icyuma gikonje rurushaho kuba rwinshi, ni ko ihinduka ry’icyuma gikonjesha rirushaho kwiyongera, kandi ni ko icyuma gikurura imbaraga. Kimwe n’umubare w’imirongo y’icyuma,ΦImiyoboro 76 irakorwa. Nta gikoresho cy’ubudahangarwa kigaragara, kandiΦImiyoboro 9.5 irakorwa. Kubera ko imiterere y’ingufu iringaniye ari minini, imiterere y’ingufu izagaragara cyane. Imiterere y’ingufu z’urukiramende rwa kare ni nini kuruta iy’ingufu z’uruziga, cyane cyane igice cy’imfuruka, imiterere y’ingufu irushaho kuba ikomeye kandi imiterere y’ingufu irushaho kugaragara.
Kugira ngo icyuma cya 304 gitangire burundu gukuraho rukuruzi iterwa n’impamvu zavuzwe haruguru, imiterere ya austenite ihamye ishobora kugarurwa binyuze mu gutunganya umuti ushyushye cyane, bityo rugakuraho rukuruzi.
By’umwihariko, bikwiye kugaragazwa ko rukuruzi y’icyuma cya 304 kidashonga bitewe n’impamvu zavuzwe haruguru itari ku rwego rumwe n’ingufu zikoreshwa mu bindi bikoresho by’icyuma cya 304 kidashonga, nka 430 na karuboni. Mu yandi magambo, rukuruzi y’icyuma cya 304 ihora igaragaza rukuruzi ruto.
Ibi bitubwira ko niba icyuma kitagira umugese gifite ingufu nke cyangwa kidafite ingufu nke, kigomba kumenyekana nk'ibikoresho 304 cyangwa 316; niba gifite ingufu zimwe na icyuma cya karuboni kandi kikagira ingufu zikomeye, kigomba kumenyekana nk'ibikoresho bitari 304.
Itsinda rya Jindalai Steeltanga inama ko mu gihe uguze ibikoresho by'icyuma kidashonga, ugomba guhitamo ibicuruzwa bivuye mu nganda zizwi. Ntukagire umururumba w'ibiciro bihendutse kandi witondere gushukwa. Jindalai Steel Group ni ikigo kinini cy’inganda zikora ibyuma bitagira umugese n’ubucuruzi gihuza ibyuma bitagira umugese bigurishwa, bitunganywa, bibikwa mu bubiko no gukwirakwiza. Yishingikirije ku cyizere n’ubufasha bw’abakozi bakorana mu gihugu no mu mahanga, ikigo cyakuze kiba kimwe mu bigo binini bihuza umusaruro n’ubucuruzi mu nganda zikora ibyuma bitagira umugese nyuma y’imyaka irenga icumi y’iterambere n’iterambere.
