Amalungu angama-304 entsimbi etyebileyo enodonga olungqingqwa ukulawula ubungakanani benkozo ngexesha lonyango lobushushu luyimfuneko, umgangatho walo ophethwe ngubushushu obungama-304 ityhubhu etyebileyo enodonga unempembelelo ebaluleke kakhulu.

Nantsi indlela yokulawula ubungakanani bobungakanani benkozo yayo Indlela Isishwankathelo ngolu hlobo lulandelayo.
(1) Khetha ubushushu obufanelekileyo bokufudumeza
Ubushushu bokufudumala buphantsi kakhulu, inkqubo yokwenza i-austenitic 304 yentsimbi etyebileyo enodonga ityhubhu iyacotha, ayinako nokwakheka ngokupheleleyo, unyango lobushushu alukwazi ukufikelela kwiimfuno. Ubushushu bobushushu buphezulu kakhulu, kulula ukufumana iinkozo ezirhabaxa ze austenite. Kubangela ukuthotywa komgangatho wokusebenza. Kufuneka kube ukhetho olufanelekileyo lobushushu bokufudumala iyahluka ngokuxhomekeke kwimiba emininzi yokwakheka kweekhemikhali ze-304 insimbi engenasici umbhobho ongqingqwa, imilo kunye nobukhulu beenxalenye, naziphi na iimfuno ezikhethekileyo, utshintsho kwicandelo lomnqamlezo kunye neemfuno ezithile zobugcisa.

Ukubamba ixesha kuthathelwa ingqalelo iingongoma ezimbini lide kakhulu okanye kubangele ingqolowa austenite enkulu iya kwandisa umjikelo wemveliso, ukunciphisa ukusebenza kakuhle, unyango ubushushu akwenzeki ukulawula umbutho eyiyo umbutho original ichaphazela intsimbi yokuqala Ngoko ke, ubukhulu eziziinkozo iintsimbi eziphezulu zekhabhoni, ukwenzela ukunqanda ukutshisa kakhulu kunye nokuqina okongeziweyo, khetha i-annealing encinci ye-spherical divergence annealing Organisation;. iklabhu emva kokukhetha ukusasazwa okukhulu kwepearlite entle ye-lamellar okanye ukucima kunye nombutho wonyango olushushu. Khetha undoqo wengqolowa ecikizekileyo 304 ityhubhu yentsimbi etyebileyo enodonga ukuya kubuntununtunu bobushushu bendalo encinci yentsimbi ecolekileyo, kwaye ke iimeko zokufudumeza eziqhelekileyo ngokupheleleyo ziqinisekisa iinkozo ezintle ze austenite.
