1. Ukwelashwa Kokushisa Kwesixazululo
Ukucaciswa okujwayelekile kokwelashwa kokushisa kwesisombululo yikho: ukushisa ukukhishwa ku-950 ° C - 1175 ° C nokuyibeka emanzini, uwoyela noma emoyeni ngemva kokugcinwa kokushisa ukuze kuqedwe ngokuphelele ama-carbides ensimbi engagqwali ukuze uthole isakhiwo sesigaba esisodwa. Ukukhethwa kwezinga lokushisa lesisombululo kuncike kokuqukethwe kwekhabhoni ensimbi ekhonjiwe. Uma kuphakeme okuqukethwe kwekhabhoni, kulapho izinga lokushisa eliqinile lesisombululo liphakama.
Ukuze kuncishiswe umehluko wokushisa phakathi kwendawo yokukhipha insimbi kanye nengqikithi phakathi nenqubo yokushisa, indlela yokushisa yokwelashwa kwesisombululo se-austenitic insimbi engagqwali kufanele ishiswe ngaphambi kokushisa okuphansi bese ishisa ngokushesha ekushiseni kwesisombululo. Isikhathi sokubamba kufanele sikhule ngokuhambisanayo njengoba ukushuba kodonga lokubunjwa kwanda.
Indawo yokupholisa yokwelapha isixazululo kungaba amanzi, uwoyela noma umoya, amanzi awo asetshenziswa kakhulu. Ukupholisa komoya kulungele kuphela ukusakaza kwensimbi enezindonga ezincane.

2. Ukuzinzisa
Insimbi engagqwali ye-Austenitic inokumelana nokugqwala okuhle kakhulu ngemuva kokwelashwa kwesixazululo. Kodwa-ke, uma ukusakaza kushisa kabusha ku-500°C-850°C noma ukusakaza kusebenza kuleli banga lokushisa, i-chromium carbide izophinde inemvula eduze komngcele wezinhlamvu ze-austenite, ibangele ukugqwala komngcele wokusanhlamvu noma ukuqhekeka kwe-weld. Lesi simo sibizwa ngokuthi ukuzwela. Ukuze kuthuthukiswe ukumelana nokugqwala kwe-intergranular kwalolu hlobo lwe-austenitic stainless steel castings, ngokuvamile kuyadingeka ukwengeza izakhi ze-alloying ezifana ne-titanium ne-niobium. Ngemuva kokwelashwa kwesisombululo, shisa kabusha ku-850 ° C - 930 ° C, bese upholisa ngokushesha. Ngale ndlela, ama-carbides e-titanium ne-niobium aqala ukunathwa yi-austenite, ngaleyo ndlela avimbele ukuna kwe-chromium carbide futhi athuthukise ukumelana nokugqwala komngcele wokusanhlamvu wensimbi engagqwali.
