430 insimbi engagqwali noma 201 insimbi engagqwali okuyinto engcono?

I-430 insimbi engagqwali ibushelelezi, ukukhathala kokushisa, i-asidi, igesi ye-alkaline, isixazululo nokunye ukumelana nokugqwala kwemidiya.Ipulasitiki ephezulu, ukuqina namandla emishini;201 Ipayipi lensimbi engagqwali linezici zokumelana ne-asidi, ukumelana ne-alkali, ukuminyana okuphezulu ngaphandle kwamaphinikhodi, njll., ukukhiqizwa kwamakesi ewashi ahlukahlukene, ikhava engezansi yebhande nezinye izinto ezisezingeni eliphezulu.201 Amapayipi ensimbi engagqwali angasetshenziswa kumapayipi okuhlobisa, amapayipi ezimboni, kanye neminye imikhiqizo engashoni.

430 insimbi engagqwali kanye 201 insimbi engagqwali umehluko

430 insimbi engagqwali insimbi engagqwali martensitic, martensitic insimbi engagqwali kanye ezejwayelekile ingxubevange steel inezici ezifanayo ukuqina ngokusebenzisa quenching, martensitic chromium insimbi engagqwali ekucimeni - izimo ukufudumala, ukwandisa okuqukethwe chromium kungandisa okuqukethwe ferritic, ngaleyo ndlela ukunciphisa ubulukhuni futhi. amandla aqinile.Ngaphansi kwezimo zokuthungatha, ubulukhuni bensimbi engagqwali ye-carbon martensitic chromium bukhuphuka ngokunyuka kokuqukethwe kwe-chromium, kuyilapho ubude kuncipha kancane.Ngaphansi kwesimo sokuqukethwe okuthile kwe-chromium, ukwanda kokuqukethwe kwekhabhoni kuzokwandisa ubulukhuni bensimbi ngemva kokucisha, futhi ipulasitiki izokwehla.

Ngemuva kokucisha izinga lokushisa eliphansi, umphumela wokwengeza we-molybdenum usobala kakhulu.Inhloso eyinhloko yokwengeza i-molybdenum ukuthuthukisa amandla, ubulukhuni kanye nomphumela wokuqina wesibili wensimbi.Kunsimbi engagqwali ye-chromium-nickel ye-martensitic, okuqukethwe kwe-δ ferrite kunsimbi kungancishiswa ngenani elithile le-nickel, ukuze insimbi ikwazi ukuthola inani eliphezulu lokuqina.

Insimbi engagqwali engu-210 iyinsimbi engagqwali ye-chromium-nickel austenitic, insimbi engagqwali ye-austenitic ayinamagnetic futhi inokuqina okuphezulu kanye nepulasitiki, kodwa amandla aphansi, akunakwenzeka ukuqinisa ngokushintsha kwesigaba, kuphela ngokusebenza okubandayo ukuze kuqiniswe.Uma i-S, i-Ca, i-Se, i-Te nezinye izakhi zengezwa, inokusebenza okuhle.Uma iqukethe i-Mo, i-Cu nezinye izakhi, ingamelana nokugqwala kwe-sulfuric acid, i-phosphoric acid, i-formic acid, i-acetic acid, i-urea njalonjalo.Uma okuqukethwe kwekhabhoni yensimbi enjalo kungaphansi kuka-0.03% noma iqukethe i-Ti, i-Ni, ingathuthukisa kakhulu ukumelana kwayo nokugqwala kwe-intergranular.I-silicon austenitic insimbi engagqwali ephezulu egxilile ye-nitric acid inokumelana nokugqwala okuhle.Ngenxa yokuthi insimbi engagqwali ye-austenitic inezakhiwo ezibanzi futhi ezinhle ezihlanganisayo, isetshenziswe kabanzi kuyo yonke imikhakha yempilo.
