Solution annealing, inozivikanwawo semhinduro yekurapa, inzira yekurapa kupisa inonyanya kushandiswa kuvandudza corrosion resistance, mechanical properties, uye chimiro chakafanana chesimbi isina tsvina.
Chii chinonzi annealing?
Annealinginzira yekurapa kupisa yakagadzirirwa kusimudzira ductility uye kushanda kwezvinhu nekudzikisa kuomarara uye kubvisa kushushikana kwemukati. Maitiro acho anosanganisira kudziyisa kunodzorwa kune imwe tembiricha, kubata patembiricha iyoyo kubvumira shanduko yechimiro, uyezve kutonhora zvishoma - kazhinji muchoto. Annealing inovandudza microstructure yezvinhu, zvichiita kuti ive yakafanana uye yakagadzikana. Inowanzo shandiswa kune simbi dzakaita sesimbi, mhangura, uye ndarira, pamwe nemidziyo yakaita segirazi uye mamwe mapolymers kukwidziridza ma mechanic uye kugadzirisa zvivakwa.
Chii chinonzi Annealed Stainless Steel?
Annealed Stainless steelisimbi isina tsvina yakarapwa annealing kupisa kuti iwedzere maitiro ayo. Kuita uku kunosanganisira kudziyisa simbi kune tembiricha yakatarwa uye wozoitonhodza zvishoma nezvishoma kudzikisa kushushikana kwemukati, kunatsiridza ductility, uye kupfavisa zvinhu. Nekuda kweizvozvo, annealed Stainless simbi inopa yepamusoro machinability, yakagadziridzwa kuumbwa, uye yakawedzera corrosion resistance kana ichienzaniswa neyayo isina kubatwa.
Chii Chinangwa cheStainless Steel Annealing?
1.Bvisa Intergranular Precipitates uye Dzorera Kurwisana kweCorrosion
Nekunyungudutsa chromium carbides (semuenzaniso, Cr₃C₂) kudzokera kune austenitic matrix, kurapwa kwemhinduro kunodzivirira kuumbwa kwenzvimbo dzakapera chromium, zvinobudirira kuvandudza kuramba kune intergranular corrosion.
2.Kuwana Homogeneous Austenitic Microstructure
Kupisa simbi isina tsvina kusvika kune tembiricha yepamusoro (kazhinji 1050 ° C-1150 ° C) inoteverwa nekudzima nekukurumidza kunoguma mune yunifomu uye yakagadzikana austenitic chikamu, icho chinosimudzira kuita kwese kwezvinhu.
3.Kuvandudza Ductility uye Toughness
Kurapa kunobvisa kushushikana kwemukati uye kunokurudzira kukwenenzvera kwezviyo, zvichiita kuti kuve nani kuumbwa uye kukanganisa kupikisa.
4.Enhance Machinability
Kune simbi-inotonhora-inoshanda Stainless simbi, mhinduro annealing inobvisa basa kuomesa mhedzisiro, kufambisa machining zviri nyore uye kuumba mukugadzirisa kunotevera.
5.Gadzirira Nyaya yeKuwedzera Kurapa Kupisa
Solution annealing inopa yakakodzera microstructural hwaro hwemaitiro akadai sekuchembera kana welding, kunyanya kunaya-yakaomeswa kana duplex simbi isina tsvina.
Mienzaniso yemhando dzesimbi dzinoshanda
• Austenitic stainless simbi (yakadai se304, 316, 321): Bvisa intergranular corrosion tendency.
• Kunaya kunoomesa simbi isina tsvina (yakadai se17-4PH): Kugadziriswa kwekugadzirisa kunoteverwa nekuchembera
• Duplex simbi isina tsvina (yakadai se2205, 2507): Kugadzirisa kurapwa kunoshandiswa kuwana yakanakira austenite + ferrite ratio.
