Mu nganda zidafite ingese, 201 zerekana ibikoresho.Ibyuma 201 bitagira umwanda bivuga ibyuma 201 bidafite ingese hamwe na aside irwanya aside.201 Ibyuma bitagira umwanda bivuga ibyuma birwanya ruswa idakomeye nko mu kirere, mu mazi no mu mazi, mu gihe ibyuma birwanya aside bivuga ibyuma birwanya ibyuma byangiza imiti nka aside, alkali n'umunyu, kandi icyitegererezo cy'igihugu ni 1Cr17Mn6Ni5N.
Ibyuma bitagira umwanda 201 bifite aside irwanya na alkali, ubwinshi bwinshi, gusya nta bubyimba, nta pinholes nibindi biranga.Byakoreshejwe mugukora ibintu bitandukanye byo kureba no gukenyera ibikoresho byo hasi.Ikoreshwa cyane cyane mugukora imiyoboro ishushanya, imiyoboro yinganda nibicuruzwa birambuye.
202 ni ikirango gisanzwe cyabanyamerika, gisimbuza 1Cr18Ni9.Icyuma cya Austenitike kitarangwamo ibyuma kirangwa nubushyuhe bwo hejuru, bityo birashobora gukoreshwa nkibyuma birwanya ubushyuhe.Kugirango ibyuma bya austenitike bidafite ibyuma bihindurwe icyiciro, bigomba gushyukwa hejuru ya 1000 ℃.Kuri 350 ℃, ntihazabaho impinduka muburyo bwa metallografiya, ni ukuvuga ko nta mpinduka zifatika zizaba mumiterere yicyuma.Bizaguka gusa kubera gushyuha, ariko impinduka ni nto kandi irashobora kwirengagizwa mubihe bisanzwe.Kubwibyo, ibyuma 202 bidafite ingese bifite ubushyuhe bwiza bwo guhangana.Kubera imikorere yacyo, ibyuma 202 bidafite ingese bikoreshwa cyane mugushushanya inyubako, ubwubatsi bwa komini, kurinda umuhanda, ibikoresho bya hoteri, ahacururizwa, ibirahuri, ibirahuri, ibikoresho rusange n’ahandi.
