Waliwo enjawulo 3 wakati w’ekyuma ekitali kizimbulukuse 304 n’ekyuma ekitali kizimbulukuse ekya austenitic:
Ekisooka, engeri z’ebintu bino ebibiri za njawulo:
1. Ebifaananyi by’ekyuma ekitali kizimbulukuse 304: ekyuma ekitali kizimbulukuse 304 kintu kya bulijjo mu kyuma ekitali kizimbulukuse, nga kirimu density ya 7.93g/cm³ Obuziyiza bw’ebbugumu eringi obwa 800 °C, erina engeri z’okukola obulungi mu kukola n’obugumu obw’amaanyi.
2. Ebifaananyi by’ekyuma ekitali kizimbulukuse ekya austenitic: Ng’oggyeeko okuziyiza okukulukuta kw’ekirungo kya asidi ekiziyiza omukka, singa kibaamu MO, Cu n’ebintu ebirala, esobola n’okuziyiza okukulukuta kwa asidi wa sulfuric, asidi wa phosphoric, asidi wa formic, acetic acid, urea, etc. Singa ekirungo kya kaboni mu kika kino kibeera kitono okusinga 0.03% oba ni, kisobola okugumira tigran. Silicon austenitic stainless steel enkulu erina okuziyiza okukulukuta okulungi eri asidi wa nitric omungi.Okukozesa

ebibiri bino kwa
1. Enkozesa y’ekyuma ekitali kizimbulukuse 304: esaanira okulongoosa emmere, okutereka n’okutambuza. Alina enkola ennungi n’okuweta. ebikyusa ebbugumu mu pulati, ebiwujjo, ebintu eby’omu nnyumba (class 1 ne 2 tableware, kabineti, payipu z’omunda, ebyuma ebibugumya amazzi, bboyiyira, bathtubs); Auto parts (windshield wipers, mufflers, ebintu ebibumbe), ebyuma eby’obujjanjabi, ebizimbisibwa, eddagala, amakolero g’emmere , ebyobulimi, ebitundu by’emmeeri, n’ebirala 304 Ekyuma ekitali kizimbulukuse kye kyuma ekimanyiddwa mu ggwanga eky’omutindo gw’emmere.
. Olw’ebintu ebijjuvu era ebirungi eby’ekyuma ekitali kizimbulukuse ekya austenitic, kibadde kikozesebwa nnyo mu makolero ag’enjawulo.
Ekyokusatu, ebika bino ebibiri bya njawulo:
. Ekirala ye Division of National Standard, Japaned Standard, American Standard n’ebirala.
. Mu mbeera ya C entono, CR erimu eri 18% ~28%, ate NI erimu 3%~10%. Ebyuma ebimu era birimu ebintu ebikola aloy nga MO, Cu, Si, Nb, Ti, ne n.
Ekyuma kino eky’ekika kino kirina ebyuma ebitaliimu buwuka (austenitic) n’eby’ekyuma ekitaliimu nsa. Bw’ogeraageranya ne ferrite, erina obuveera obusingako n’obugumu, tewali bbugumu lya kisenge brittleness, n’okulongoosa ennyo intergranular corrosion resistance n’okukola welding.
Mu kiseera kye kimu, era ekuuma 475 °C brittleness n’obutambuzi obw’ebbugumu obw’amaanyi obw’ekyuma ekitali kizimbulukuse eky’ekika kya ferritic, era erina engeri za superplasticity. Bw’ogeraageranya n’ekyuma ekitali kizimbulukuse ekya austenitic, kirina amaanyi mangi era nga kirongooseddwa nnyo okuziyiza okukulukuta wakati w’ensengekera n’okukulukuta kwa chloride stress. Duplex stainless steel erina okuziyiza okukulukuta okulungi ennyo era nga nayo kyuma ekitali kizimbulukuse ekikekkereza nikele.
Londa Hangao Tech (Ebyuma bya Seko) High precision ekyuma ekitali kizimbulukuse welded payipu okufulumya layini austenitic tube mill ekyuma . okukola ku kukola ebyuma ebitali bimenyamenya 304 ne payipu za austenitic stainless steel welded mu kiseera kye kimu. Enzimba ya archway ne roller bearing zirongoosebwa okukendeeza ku shaft runout n’okulongoosa ennyo precision ya steel pipe. Ekitundu kya forming welding era kisobola okukozesa shielding gas welding box okukendeeza oxidation n’okufuna weld ey’omutindo ogwa waggulu.
