I-UNS S30815 Insimbi Engagqwali

I-UNS S30815/253MA/EN 1.4835 iyibanga elihlanganisa izakhiwo zesevisi ezinhle kakhulu emazingeni okushisa aphezulu kalula ukwenza. Imelana ne-oxidation emazingeni okushisa afinyelela ku-1150°C futhi inganikeza isevisi ephakeme kune-Grade 310 emkhathini we-carbon, nitrogen kanye nesibabule.

I-UNS S30815 iqukethe inani eliphansi le-nickel, elinikeza inzuzo ethile ekwehliseni umoya we-sulphide uma iqhathaniswa nama-alloys aphezulu e-nickel kanye neBanga 310.

Ukufakwa kwe-chromium ephezulu, i-silicon, i-nitrogen ne-cerium kunikeza ukuqina okuhle kwe-oxide okungu-253MA, amandla okushisa aphakeme (ukwenyuka) kanye nokumelana okuhle kakhulu nemvula yesigaba se-sigma. Isakhiwo se-austenitic sinikeza leli banga ukuqina okuhle kakhulu, ngisho naphansi kwamazinga okushisa e-cryogenic.

Ku-cerium kufanele kwengezwe inani lezinye izinsimbi zomhlaba ezingavamile, kusukela ekuhlanganiseni
ithatha uhlobo lwensimbi ye-misch equkethe cishe u-50% Ce.

ukwelashwa ukushisa
Isixazululo annealing 1020-1120ºC. Ukubamba isikhathi ekuxazululeni izinga lokushisa le-annealing cishe. 30 min., okulandelwa ukupholisa ngokushesha emoyeni noma emanzini.

Ukuphatha
Leli banga alikwazi ukwenziwa lukhuni ukwelashwa ngokushisa. Kodwa kungenziwa lukhuni ngokusebenza okubandayo.

yokukhiqiza
Ukwakheka okushisayo nokubandayo
Ukwakhiwa okushisayo kufanele kwenziwe ebangeni lokushisa lika-1150-900 ° C. Ukuvala isixazululo ngokuvamile akudingekile njengoba okokusebenza kuzovezwa kumazinga okushisa aphezulu uma kusebenza. Njengezinsimbi ezingenasici ezivamile ze-austenitic, izinto ezibonakalayo zingakhiwa kalula ezimweni ezibandayo. Ngenxa yokuqukethwe kwayo kwe-nitrogen ephezulu uma kuqhathaniswa, amandla emishini e-EN 1.4835 aphezulu futhi amandla okuguqula ayadingeka. Umshini Amandla obufakazi obuphakeme obuqhathaniswa be-EN 1.4835 kanye nokuthambekela kwayo ekubandeni kuqiniswe kufanele kucatshangelwe maqondana nokwenza imishini.
