254SMO ukwakheka kwamakhemikhali ensimbi engagqwali

254SMO Ipayipi Lensimbi Engagqwali,1.4547 Ipayipi Lensimbi Engagqwali,S31254 Ipayipi Lensimbi Engenasici,F44 Ipayipi Lensimbi Engagqwali

Incazelo:

I-254SMO iyinsimbi engagqwali ye-austenitic.Ngenxa yokuqukethwe kwayo okuphezulu kwe-molybdenum, inokumelana okuphezulu kakhulu nokugqwala nokugqwala kwemifantu.I-254SMO insimbi engagqwali yathuthukiswa futhi yathuthukiswa ukuthi isetshenziswe endaweni equkethe i-halide efana namanzi olwandle.I-254SMO futhi inokumelana okuhle nokugqwala okufanayo, ikakhulukazi ku-halide equkethe ama-asidi, aphakeme kunensimbi evamile engagqwali.I-C yayo iqukethe <0.03%, ngakho ibizwa nge-pure austenitic stainless steel.Insimbi engagqwali enkulu iwuhlobo lwensimbi ekhethekile engagqwali, okokuqala ekwakhekeni kwamakhemikhali ihlukile kunensimbi engagqwali evamile, iyinsimbi engagqwali ephezulu ene-nickel ephezulu, i-chromium ephezulu, i-molybdenum ephezulu.Phakathi kwazo, i-254SMo equkethe i-6% Mo inokumelana nokugqwala okuhle kakhulu kwendawo, ukumelana nokugoba okuhle (PI≥40) kanye nokumelana nokugqwala kwengcindezi ngaphansi kwezimo zamanzi olwandle, i-aeration, igebe kanye ne-low speed scour.Kuyinto ethatha indawo ye-Ni-based alloy ne-titanium alloy.Okwesibili, ekusebenzeni kokushisa okuphezulu noma ukumelana nokugqwala, ngokushisa okuphezulu okuphezulu kakhulu noma ukumelana nokugqwala, akuthathelwa indawo yinsimbi engagqwali engu-304.Ngaphezu kwalokho, kusukela ekuhlukaniseni insimbi engagqwali, isakhiwo esikhethekile sensimbi engenasici siyisakhiwo esizinzile se-austenitic metallographic.
Ngenxa yokuthi le nsimbi ekhethekile engagqwali iwuhlobo lwezinto eziphezulu ze-alloy, ngakho-ke inqubo yokukhiqiza iyinkimbinkimbi kakhulu, ngokuvamile abantu bangathembela kuphela enqubweni yendabuko yokwenza le nsimbi ekhethekile engagqwali, efana ne-perfusion, forging, calendering njalonjalo.
 Amazinga kazwelonke:I-UNS S31254, DIN/EN 1.4547, ASTM A280, ASME SA-280
Izinto zokushisela ezisekelayo:Intambo ye-ERNICRMO-3, i-EnICRmo-3 electrode

254SMO ukwakheka kwamakhemikhali ensimbi engagqwali

Ukwakheka kwamakhemikhali:

Ukumelana nezinga lokushisa eliphezulu

1. Ukuhlola okubanzi kwenkambu nolwazi olubanzi lubonise ukuthi ngisho namazinga okushisa aphakeme kancane, i-254SMO inokumelana okuphezulu kakhulu nokugqwala kokugqwala emanzini olwandle, okunezinhlobo ezimbalwa kuphela zensimbi engagqwali.

2. Ukumelana nokugqwala kwe-254SMO kuzisombululo ze-halide ezine-acidic ne-oxidizing njengalezo ezidingekayo ekukhiqizweni kwephepha kuqhathaniswa nalokho kwesisekelo esiqinile se-nickel-base kanye nama-alloys e-titanium.

3. Ngenxa yokuqukethwe kwayo kwe-nitrogen ephezulu, i-254SMO inamandla amakhulu emishini kunezinye izinhlobo zensimbi engagqwali ye-austenitic.Ngaphezu kwalokho, i-254SMO inokuductility okuphezulu namandla okuthinta kanye nokushisela okuhle.

4. Okuqukethwe okuphezulu kwe-molybdenum okungu-254SMO kuyenza ibe nezinga eliphakeme le-oxidation lapho i-annealing, okuholela endaweni elukhuni kunensimbi engagqwali evamile ngemva kokukhetha.Kodwa lokhu akunawo umthelela omubi ekuphikiseni ukugqwala kwensimbi.

254SMO ukwakheka kwamakhemikhali ensimbi engagqwali

Isicelo:
1. Ulwandle: Izakhiwo zasolwandle endaweni yasolwandle, ukuchithwa kwamanzi olwandle usawoti, i-mariculture, ukushintshaniswa kokushisa kwamanzi olwandle, njengamapayipi okujiya anezindonga ezincane ezipholiswe ngamanzi olwandle ezikhungweni zikagesi, okokusebenza kokukhipha usawoti emanzini, ngisho nasezinsizeni lapho amanzi olwandle engeke ageleze, njll.
2. Inkambu yokuvikela imvelo: idivayisi ye-thermal power generation flue gas desulfurization, ukwelashwa kwamanzi angcolile, izingxenye eziyinhloko yilezi: umzimba we-absorber tower, flue, panel panels, izingxenye zangaphakathi, uhlelo lwesifutho, njll.
3. Amandla: ukukhiqizwa kwamandla e-athomu, ukusetshenziswa okuphelele kwamalahle, ukukhiqizwa kwamandla olwandle, njll.
4. Imboni ye-Petrochemical: ukucwengwa kukawoyela, okokusebenza kwamakhemikhali, okokusebenza kwe-petrochemical, okufana nezivunguvungu emishinini ye-petrochemical, njll.
5. Inkundla yokudla: ukwenza usawoti, imboni yokukhipha usawoti emanzini, njengokwenza usawoti noma imishini yokukhipha usawoti emanzini, ukwenziwa kwe-soy sauce, njll.
6. Imvelo ye-ion ye-chloride ene-concentration ephezulu: imboni yokwenza iphepha, i-pulp kanye nemishini yokuxubha amaphepha, njengama-pulp digester, imishini yokuxubha, imiphongolo yokuhluza kanye nama-roller okucindezelayo nezinye izinto zokuxubha.
