1. Solution Heat Treatment
Iyo yakajairika yemhinduro yekupisa kurapwa ndeye: kupisa kukanda ku950 ° C - 1175 ° C uye kuiisa mumvura, mafuta kana mhepo mushure mekuchengetedza kupisa kuti iparadze zvachose iyo carbides musimbi isina tsvina kuti uwane imwe-chikamu chimiro. Sarudzo yekupisa tembiricha inoenderana nekabhoni yemukati musimbi yakakandwa. Iyo yakakwirira iyo kabhoni yemukati, inokwira iyo yakasimba mhinduro tembiricha inodiwa.
Kuti uderedze mutsauko wekushisa pakati pepamusoro pesimbi yekukanda uye musimboti panguva yekupisa, nzira yekudziya yemhinduro yekurapa austenitic simbi isina tsvina inofanira kupiswa pamhepo yakadzika uye nekukurumidza kupisa kune tembiricha yemhinduro. Iyo nguva yekubata inofanirwa kuwedzera zvinoenderana nekuwanda kwemadziro ekukanda kunowedzera.
Iyo yekutonhodza yekurapa mhinduro inogona kunge iri mvura, mafuta kana mhepo, iyo mvura ndiyo inonyanya kushandiswa. Kutonhodza kwemhepo kwakakodzera chete kune dzakatetepa-madziro simbi castings.

2. Kudzikamisa
Austenitic Stainless simbi ine yakanakisa corrosion resistance mushure mekugadzirisa mhinduro. Nekudaro, kana kukanda kuchipisazve kusvika ku500 ° C-850 ° C kana kukanda kunoshanda mune ino tembiricha renji, chromium carbide inonaya zvakare ichitevedza muganho wezviyo we austenite, zvichiita kuti zviyo muganhu zviite ngura kana weld kuputika. Chiitiko ichi chinonzi sensitization. Kuti uvandudze iyo intergranular corrosion resistance yeaustenitic stainless simbi castings, zvinowanzodiwa kuwedzera alloying zvinhu senge titanium uye niobium. Mushure mekugadzirisa kugadzirisa, dzorerazve ku 850 ° C - 930 ° C, uye wobva wakurumidza kutonhora. Nenzira iyi, ma carbides etitanium uye niobium anotanga kudonha kubva ku austenite, nekudaro kudzivirira kunaya kwe chromium carbide uye kuvandudza muganhu wezviyo kuramba ngura yesimbi isina tsvina.
