Ukusebenza kwepleyiti yensimbi engenasici: ukuxhathisa umhlwa

Insimbi engenasici inokumelana ne-corrosion jikelele efana ne-nickel-chromium alloy engazinzanga 304. Ukufudumeza ixesha elide kwiqondo lokushisa kwe-chromium carbide degrees kunokuchaphazela i-alloys 321 kunye ne-347 kwimidiya eyingozi. Ikakhulu isetyenziswe kwizicelo zokushisa okuphezulu, izinto ezifunekayo ukuba zibe nokuchasana okunamandla kwi-sensitization ukukhusela i-corrosion ye-intergranular kumaqondo aphantsi.

ukumelana nobushushu obuphezulu be-oxidation

Iipleyiti zensimbi ezingenasici zixhathisa kwi-oxidation yobushushu obuphezulu, kodwa izinga le-oxidation liya kuchatshazelwa zizinto zendalo ezifana nokuvezwa kwendalo kunye nokumila kwemveliso.

iimpawu zomzimba

I-coefficient yokudlulisa ubushushu bentsimbi ixhomekeke kwizinto ezingaphandle kwe-thermal conductivity yentsimbi. Kwiimeko ezininzi, i-coefficient yokutshatyalaliswa kobushushu befilimu, isikali se-oxide kunye nemeko yendawo yentsimbi. Intsimbi engenastainless igcina umphezulu ucocekile, ngoko ke iqhuba ubushushu ngcono kunezinye iintsimbi ezine-thermal conductivity ephezulu. I-Liaocheng Suntory iMimiselo yeNsimbi engenaStainless 8. ImiGangatho yobuGcisa yeePlati zeNsimbi ezingenasici Amacwecwe ensimbi anamandla aphezulu anokumelana ne-corrosion egqwesileyo, ukugoba ukusebenza, ukuqina kwamalungu adityanisiweyo, kunye nokunyanzeliswa kwesitampu seendawo ezidityanisiweyo kunye neendlela zabo zokuvelisa. Ngokukodwa, iqulethe i-C: 0.02% okanye ngaphantsi, i-N: 0.02% okanye ngaphantsi, i-Cr: i-11% okanye ngaphezulu nangaphantsi kwe-17%, iqulethe ngokufanelekileyo i-Si, Mn, P, S, Al, Ni, kunye ne-12≤Cr Mo 1.5Si≤17 eyanelisayo. Fudumeza ipleyiti yensimbi engenasici nge-1≤Ni 30(CN) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, 0.006≤CN≤0.030 ukuya kwi-850～1250℃ okanye iqondo lokupholisa ubushushu/ukupholisa ngaphezulu. Ngale ndlela, inokuba yintsimbi yentsimbi engenamandla, enesakhiwo esingaphezulu kwe-12% yevolumu ye-martensite, inamandla amakhulu angaphezu kwe-730MPa, ukuxhathisa ukubola kunye nokusebenza ukugoba, kwaye inobunzima obubalaseleyo kwindawo echaphazelekayo yokushisa. Ukusetyenziswa ngokuphindaphindiweyo kwe-Mo, B, njl.

Ioksijini kunye namadangatye egesi akakwazi ukusika intsimbi engatyiwayo ngenxa yokuba intsimbi engatyiwayo ayidityaniswa lula.
