SUS304 (SUS bisobanura ibyuma bidafite ibyuma) ibyuma bitagira umuyonga austenite mubisanzwe byitwa SS304 cyangwa AISI 304 mukiyapani. Itandukaniro nyamukuru hagati yibikoresho byombi ntabwo ari ibintu bifatika cyangwa ibiranga, ahubwo ni uburyo byavuzwe muri Amerika no mu Buyapani.
Ariko, hariho itandukaniro ryibikoresho hagati yibyuma byombi. Urugero rumwe, ingero za SS304 zabonetse muri Amerika hamwe na SUS304 zakuwe mu Buyapani zoherejwe muri laboratoire kugira ngo zipime.
SUS304 (JIS isanzwe) nimwe muburyo bukoreshwa cyane mubyuma bidafite ingese. Igizwe na 18% Cr (chromium) na 8% Ni (nikel). Irashobora gukomeza imbaraga zayo nubushyuhe bukabije mubushyuhe bwo hejuru kandi buke. Ifite kandi gusudira neza, imiterere yubukanishi, gukora ubukonje no kurwanya ruswa mubushyuhe bwicyumba. SS304 (ANSI 304) nicyo cyuma gikoreshwa cyane mugihe cyo gukora ibindi bikoresho byuma, kandi mubisanzwe bigurwa mubihe bikonje cyangwa bifatika. Kimwe na SUS304, SS304 nayo irimo 18% Cr na 8% Ni, bityo yitwa 18/8. SS304 ifite gusudira neza, kurwanya ubushyuhe, kurwanya ruswa, imbaraga zubushyuhe buke, gukora, imiterere yubukanishi, kuvura ubushyuhe ntabwo bikomera, kunama, kashe ya isothermal akazi ni byiza. SS304 ikoreshwa cyane mu nganda nyinshi, zirimo ibiryo, ubuvuzi n'imirimo yo gushushanya. Ibigize imiti ya SUS304 na SS 304

Kurwanya ruswa ya 304 ibyuma bitagira umwanda Nkuko twese tubizi, 304 ibyuma bitagira umwanda bikora neza mubidukikije bitandukanye byikirere hamwe nibitangazamakuru byangirika. Nyamara, ahantu hashyushye ya chloride, iyo ubushyuhe burenze 60 ° C, bukunze kwibasirwa na ruswa, imitsi ya ruswa hamwe na ruswa. Ku bushyuhe bw’ibidukikije, bifatwa kandi ko ishobora guhangana n’amazi yo kunywa arimo chloride igera kuri 200 mg / l.Ibiranga umubiri bya SUS304 na SS304
Ibikoresho byombi byegeranye cyane mubintu byumubiri nubumara, biroroshye rero kuvuga ko aribikoresho bimwe. Mu buryo nk'ubwo, itandukaniro nyamukuru hagati y’ibihugu byombi ni uburinganire hagati y’Amerika n'Ubuyapani. Ibi bivuze ko keretse niba amabwiriza cyangwa ibisabwa byihariye bigaragazwa nigihugu cyangwa umukiriya, buri kintu gishobora gukoreshwa muburyo butandukanye.
