Ubwa mbere, tugomba gusobanukirwa imiterere y’imiti n’imiterere y’amasahani ya 201 atagira umugese. Isahani ya 201 atagira umugese ni ibikoresho bya alloy birimo 17% kugeza 19% bya chromium, 4% kugeza 6% bya nikeli na 0.15% kugeza 0.25% by'icyuma gito cya karuboni. Iyi alloy ifite ubushobozi bwo kurwanya ingese n’ubushyuhe bwinshi, kandi ishobora gukoreshwa igihe kirekire mu bushyuhe bwinshi n’ibintu byangiza. Byongeye kandi, isahani ya 201 atagira umugese ifite ubushobozi bwo gutunganya no gukomera, ishobora guhaza ibyifuzo by’inganda zitandukanye.
Icya kabiri, tugomba gusobanukirwa imikorere y'ubushyuhe bwinshi bw'icyuma gikozwe muri 201. Dukurikije ubushakashatsi bufatika, imikorere y'ubushyuhe bwinshi bw'icyuma gikozwe muri 201 iterwa n'ingano ya chromium n'ingano ya karuboni. Iyo ingano ya chromium iri hejuru ya 10.5%, icyuma gikozwe muri 201 gifite ubushyuhe bwinshi kandi gishobora gukoreshwa igihe kirekire mu bushyuhe bwinshi. Uko ingano ya karuboni iba nke, ni ko ingano y'ubushyuhe bwinshi bw'icyuma gikozwe muri 201 iba nziza. Kubwibyo, imikorere y'ubushyuhe bwinshi bw'icyuma gikozwe muri 201 iterwa n'imiterere yacyo yihariye y'ibinyabutabire n'uburyo gikorwa.
Amaherezo, tugomba gusobanukirwa imikorere y'ubushyuhe bwinshi bw'icyuma cya 201 mu bikorwa bifatika. Dukurikije igerageza n'uburambe mu ikoreshwa, icyuma cya 201 gishobora gukoreshwa igihe kirekire mu bushyuhe bwinshi buri munsi ya 500 ℃, kandi imikorere yacyo izagabanuka buhoro buhoro mu bushyuhe bwinshi buri hejuru ya 500 ℃. Kubwibyo, iyo ukoresha icyuma cya 201 mu bushyuhe bwinshi, ni ngombwa guhitamo no gushushanya hakurikijwe ibisabwa byihariye byo gukoresha n'imiterere y'ibidukikije.
Muri make, icyuma cya 201 cya stainless steel ni icyuma cya stainless steel gifite ubushyuhe bwinshi. Ubushyuhe bwacyo bukabije buterwa n'imiterere yacyo yihariye y'ibinyabutabire n'uburyo cyakozwemo, kandi muri rusange gishobora gukoreshwa igihe kirekire mu bushyuhe buri munsi ya 500 °C. Mu bikorwa bifatika, kigomba gutoranywa no gushushanywa hakurikijwe ibisabwa byihariye byo gukoreshwa n'imiterere y'ibidukikije kugira ngo kigire imikorere myiza n'igihe kirekire cyo gukora.
