Kugadzira uye Kupisa Kurapa
Machinability
Kutsvaga michina yekuongorora simbi dzako?
Grade 317 Stainless simbi yakasimba kudarika 304 Stainless simbi.Inokurudzirwa kushandisa chip breakers.Hardenability yeiyi alloy ichaderedzwa kana nguva dzose yekudya uye yakaderera kumhanya inoshandiswa.
Welding
Giredhi 317 simbi isina simbi inogona kuvezwa uchishandisa fusion uye nzira dzekupikisa.Oxyacetylene welding nzira haina kusarudzwa kune iyi alloy.AWS E/ER317 kana 317L yekuzadza simbi inogona kushandiswa kuwana mhedzisiro yakanaka.
Hot Working
Giredhi 317 simbi isina tsvina inogona kupisa ichishanda uchishandisa ese akajairwa kupisa kushanda maitiro.Inopisa pa1149-1260°C (2100-2300°F).Hazvifanirwe kupiswa pasi pe927°C (1700°F).Post-work annealing inogona kuitwa kuchengetedza corrosion resistance property.
Kutonhora Kushanda
Kutsika, kuveura, kudhirowa, uye musoro zvinogona kuitwa zvinobudirira.Post-work annealing inoitwa kuitira kuderedza kushushikana kwemukati.
