Machining Stainless simbi giredhi 317L inoda yakaderera kumhanya uye anogara achidyisa kuderedza maitiro ayo ekushanda nesimba.Simbi iyi yakasimba kudarika giredhi 304 simbi isina tsvina ine tambo refu;zvisinei, kushandisa chip breakers kunokurudzirwa.Welding inogona kuitwa uchishandisa yakawanda yakajairwa fusion uye nzira dzekuramba.Oxyacetylene welding inofanira kudziviswa.AWS E/ER 317L simbi yekuzadza inokurudzirwa.
Zvakajairwa zvinopisa zvinoshanda zvinogona kuitwa.Nyaya yacho inofanira kupisa kusvika 1149-1260 ° C (2100-2300 ° F);zvisinei, haifaniri kupiswa pasi pe927°C (1700°F).Kuti uwedzere kusadzivirirwa kwecorrosion, inokurudzirwa post-work annealing.
Kuveura, kutsika, musoro uye kudhirowa zvinogoneka negiredhi 317L simbi isina tsvina, uye post-work annealing inokurudzirwa kubvisa kushushikana kwemukati.Annealing inoitwa pa 1010-1121 ° C (1850-2050 ° F), iyo inofanira kuteverwa nekukurumidza kutonhora.
Giredhi 317L simbi isina tsvina haipindure pakupisa kurapwa.
Applications
Giredhi 317L simbi isina tsvina inoshandiswa zvakanyanya mune zvinotevera maapplication:
- Condensers mu fossil
- Kugadzirwa kwemapepa uye mapepa
- Zviteshi zvemagetsi zvemagetsi enyukireya
- Kemikari uye petrochemical process michina.
