Isingeniso
Insimbi engagqwali grade 317L inguqulo ye-carbon low grade 317 insimbi engagqwali.Inamandla afanayo aphezulu kanye nokumelana nokugqwala njengensimbi engu-317 kodwa ingakhiqiza ama-welds aqinile ngenxa yokuqukethwe kwekhabhoni ephansi.
Idatha elandelayo ihlinzeka ngesifinyezo sezinga lensimbi engagqwali 317L.
I-Stainless Steel Grade 317L (UNS S31703) ukwakheka kwamakhemikhali

Ukucupha ibanga lensimbi engagqwali 317L kudinga isivinini esiphansi kanye nokudla okungapheli ukuze kuncishiswe ukuthambekela kwayo ekusebenzeni kanzima.Le nsimbi iqinile kune-grade 304 yensimbi engagqwali ene-chip ende enezintambo;Nokho, kunconywa ukusebenzisa ama-chip breakers.Ukushisela kungenziwa kusetshenziswa iningi lezindlela ezijwayelekile zokuhlanganisa nezindlela zokumelana.Ukushisela i-Oxyacetylene kufanele kugwenywe.I-AWS E/ER 317L yensimbi yokugcwalisa iyanconywa.
Izinqubo ezivamile zokusebenza ezishisayo zingenziwa.Izinto ezibonakalayo kufanele zishiswe ku-1149-1260 ° C (2100-2300 ° F);kodwa-ke, akufanele ishiswe ngaphansi kuka-927°C (1700°F).Ukuze kuthuthukiswe ukumelana nokugqwala, kunconyelwa ukuhunyushwa kwangemva komsebenzi.
Ukugunda, ukugxiviza, isihloko nokudweba kungenzeka nge-grade 317L yensimbi engagqwali, futhi ukudonsa ngemva komsebenzi kuyanconywa ukuze kuqedwe ukucindezeleka kwangaphakathi.I-Annealing yenziwa ku-1010-1121°C (1850-2050°F), okufanele ilandelwe ukupholisa ngokushesha.
Ibanga 317L insimbi engagqwali ayiphenduli ukwelashwa ukushisa.
Izinhlelo zokusebenza
I-Grade 317L yensimbi engagqwali isetshenziswa kabanzi kulezi zicelo ezilandelayo:
- Ama-condensers ku-fossil
- Ukukhiqizwa kwe-Pulp namaphepha
- Iziteshi zokuphehla amandla enuzi
- Amakhemikhali kanye nemishini yenqubo ye-petrochemical.
