I-SUS304 (i-SUS ithetha insimbi engenasici yentsimbi) i-austenite yensimbi engenasici idla ngokubizwa ngokuba yi-SS304 okanye i-AISI 304 ngesiJapan.Umahluko omkhulu phakathi kwezinto ezimbini azikho naziphi na iimpawu ezibonakalayo okanye iimpawu, kodwa indlela ezicatshulwe ngayo eUnited States naseJapan.
Nangona kunjalo, kukho ukungafani komatshini phakathi kweentsimbi ezimbini.Kumzekelo omnye, iisampulu ze-SS304 ezifunyenwe kwimithombo yase-US kunye neesampulu ze-SUS304 ezifunyenwe kwimithombo yaseJapan zathunyelwa elabhoratri ukuze zivavanywe.
I-SUS304 (umgangatho we-JIS) yenye yezona nguqulelo zisetyenziswa kakhulu kwintsimbi engenasici.Yenziwe nge-18% yeCr (chromium) kunye ne-8% ye-Nickel.Isenako ukugcina amandla ayo kunye nokumelana nobushushu kumaqondo aphezulu kunye namaqondo aphantsi.Ikwanayo ne-weldability elungileyo, iipropathi zoomatshini, ukusebenza okubandayo kunye nokumelana nomhlwa kwiqondo lobushushu begumbi.I-SS304 (ANSI 304) iyona nto isetyenziswa ngokuqhelekileyo insimbi engenasici xa isenza ezinye izinto ezingenasici kwaye zivame ukuthengwa phantsi kweemeko ezibandayo okanye ezinqabileyo.Ngokufanayo ne-SUS304, i-SS304 nayo iqulethe i-18% Cr kunye ne-8% ye-Ni, ngoko ibizwa ngokuba yi-18/8.I-SS304 ine-weldability elungileyo, ukuxhathisa ubushushu, ukuxhathisa ubushushu, amandla asezantsi obushushu, ukusebenza, iipropathi zoomatshini, unyango lobushushu aluqiniswanga, ukugoba, ukunyathela ukusebenza kwe-isothermal kulungile.I-SS304 isetyenziswa ngokubanzi kumashishini amaninzi, kubandakanywa ukutya, umsebenzi wonyango kunye nomsebenzi wokuhombisa.Ukwakhiwa kweekhemikhali ze-SUS304 kunye ne-SS 304.

Ukumelana ne-Corrosion ye-304 yensimbi engenasici njengoko sonke sisazi, i-304 yensimbi engenasici isebenza kakuhle kwiindawo ezahlukeneyo zomoya kunye neendaba ezitshabalalisayo.Nangona kunjalo, kwindawo efudumeleyo yekloridi, xa iqondo lobushushu lingaphezulu kwe-60 ° C, lithanda ukugrumba, ukubola kunye noxinzelelo lwe-corrosion.Kwiqondo lokushisa eliphantsi, likwabonwa ukuba liyakwazi ukumelana namanzi okusela aqulethe malunga ne-200 mg / l chloride.Iimpawu ezibonakalayo ze-SUS304 kunye ne-SS304
Ezi zinto zimbini zisondele kakhulu kwizinto eziphathekayo kunye neekhemikhali, ngoko kulula ukuthetha ukuba zizinto ezifanayo.Ngokufanayo, umahluko omkhulu phakathi kwala mazwe mabini kukubekwa emgangathweni phakathi kweUnited States neJapan.Oku kuthetha ukuba ngaphandle kokuba imimiselo ethile okanye iimfuno zichazwe lilizwe okanye umthengi, into nganye ingasetyenziselwa enye indlela.
