INKCAZO
Insimbi engenasici i-317L libakala le-molybdenum eliqulethe i-carbon ephantsi, kunye nezongezo ze-chromium, i-nickel, kunye ne-molybdenum. Oku kunika ukuxhathisa okungcono kokubola kunye nokwanda kokumelana nokuhlaselwa kweekhemikhali ukusuka kwi-acetic, i-tartaric, i-formic, i-citric, kunye ne-sulfuric acids. I-317L iityhubhu / imibhobho ibonelela ngokunyuka okuphezulu, kunye nokuchasana nokuvuselela xa i-welded, ngenxa yomxholo wekhabhoni ephantsi. Izibonelelo ezongeziweyo zibandakanya uxinzelelo lokuxhathisa ukuphuka, kunye namandla okuqina kumaqondo obushushu aphakamileyo. Iipayipi zensimbi zeBanga le-317l azikho i-magnetic kwimeko ye-annealed. Nangona kunjalo, i-post-welding magnetism encinci inokubonwa.
I-317L IIPROPATI ZOMbhobho wentsimbi ENGXINQI
I-317L iityhubhu zentsimbi ezibonelelwe yiArch City Steel & Alloy ziqulathe ezi mpawu zilandelayo:
Ukuxhathisa ukonakala:
- Ibonisa ukuxhathisa okugqwesileyo kwi-corrosion kwiindawo ezahlukeneyo, ngakumbi kwindawo ene-acidic chloride kunye noluhlu olubanzi lweekhemikhali.
- Ukuchasana kokugqwesa okugqwesileyo kwizicelo apho kufuneka ungcoliseko oluncinci
- I-317L ityhubhu yentsimbi / umbhobho onomxholo ophantsi wekhabhoni unika ukuxhathisa okulungileyo kwi-corrosion ye-intergranular
- Utyekelo lwentsimbi emhadini xa idibana nekloridi, ibromides, i-phosphorus acids, kunye ne-iodides iyacinezelwa.
Ukumelana nobushushu:
- Ukuchasana okugqwesileyo kwi-oxidation ngenxa yomxholo we-chromium-nickel-molybdenum.
- Ibonisa izinga eliphantsi lokulinganisa kwiqondo lokushisa ukuya kwi-1600-1650 ° F (871-899 ° C), kwi-atmospheres eqhelekileyo.
Iimpawu zeWelding:
- Ngaphandle kwe-oxyacetylene welding, idityaniswe ngempumelelo yiyo yonke i-fusion eqhelekileyo kunye neendlela zokumelana.
- Intsimbi yokuzalisa ngesiseko se-nickel kunye ne-chromium eyaneleyo kunye nomxholo we-molybdenum kufuneka isetyenziswe ukuwelda Uhlobo lwe-317L yentsimbi. Oku kunceda ekwandiseni ukumelana nomhlwa kwemveliso edityanisiweyo. I-AWS E317L/ER317L okanye i-austenitic, isinyithi esisezantsi se-carbon filler esinomxholo ophezulu we-molybdenum kune-grade 317L nayo ingasetyenziswa.
Ubuchule:
- Ukusebenza kwizantya eziphantsi kunye nokutya rhoqo kunceda ukunciphisa ukuthambekela kwemibhobho yebakala 317L ukuqina.
- IBanga le-317L lemibhobho yentsimbi engenasici yomelele kune-304 engenastainless kwaye ixhomekeke kwitshiphu ende nelinentambo xa isenziwa ngoomatshini. Ngoko ke, kucetyiswa ukuba kusetyenziswe i-chip breakers.
Usetyenziso:
IBanga le-317L iityhubhu zensimbi engenastainless zisetyenziselwa ukuphatha utywala, idayi yeasidi, izisombululo zebleaching, imixube ye-acetylating kunye ne-nitrating, njl njl. Ezinye izicelo ezikhethekileyo zebakala 317L iityhubhu kunye nemibhobho ibandakanya:
- Izixhobo zokulungisa iikhemikhali kunye nepetrochemical
- Iphepha kunye nezixhobo zokuphatha i-pulp
- Izixhobo zokulungisa ukutya
- Iicondenser kwizikhululo zenyukliya kunye nefosili
- Izixhobo zeTelephu
