Intshayelelo
I-Stainless steel grade 317L yinguqu yekhabhoni ephantsi ye-317 yensimbi engenasici.Inamandla afanayo aphezulu kunye nokuxhathisa ukubola njengentsimbi ye-317 kodwa inokuvelisa i-welds eqinile ngenxa yomxholo wekhabhoni ephantsi.
Le datha ilandelayo ibonelela ngesishwankathelo sebakala lensimbi engenastainless 317L.

I-Machining steel stainless grade 317L idinga isantya esiphantsi kunye nokutya rhoqo ukunciphisa ukuthambekela kwayo ukusebenza nzima.Le ntsimbi yomelele kunebakala lama-304 intsimbi engatyiwayo enentambo ende;nangona kunjalo, kucetyiswa ukusebenzisa iziqhekeza zetshiphu.I-Welding inokwenziwa kusetyenziswa uninzi lweendlela eziqhelekileyo zokudibanisa kunye nokumelana.I-Oxyacetylene welding kufuneka igwenywe.I-AWS E / ER 317L yentsimbi yokuzalisa iyacetyiswa.
Iinkqubo eziqhelekileyo zokusebenza ezishushu zingenziwa.Izinto eziphathekayo kufuneka zitshiswe kwi-1149-1260 ° C (2100-2300 ° F);nangona kunjalo, akufanele itshiswe ngaphantsi kwe-927 ° C (1700 ° F).Ukwandisa ukumelana nomhlwa, kucetyiswa ukuba kufakwe annaal emva komsebenzi.
Ukucheba, ukunyathela, ukukhanda kunye nokudweba kunokwenzeka ngebakala le-317L yensimbi engenasici, kunye nokukhutshwa emva komsebenzi kunconywa ukuphelisa uxinzelelo lwangaphakathi.I-Anealing yenziwa kwi-1010-1121 ° C (1850-2050 ° F), ekufuneka ilandelwe ngokupholisa ngokukhawuleza.
IBakala 317L insimbi engenasici ayiphenduli kunyango lobushushu.
Usetyenziso
IBakala 317L insimbi engenasici isetyenziswa ngokubanzi kwezi zicelo zilandelayo:
- Iicondensers kwifosili
- Ukwenziwa kwePulp kunye nephepha
- Izikhululo zokuvelisa amandla ngenyukliya
- Izixhobo zenkqubo yeMichiza kunye nepetrochemical.
