Inconel 718 is Austenitic chimiro, kunaya kwemvura kuomarara kunogadzira "γ" kwakaita kuti ive yakanakisa mechanic kuita.G mvura muganho inoburitsa "δ" yakaita kuti ive yepurasitiki yakanakisa mukupisa kupisa.ine kupikisa zvakanyanya kushushikana nekupwanya kukoromoka uye kugona kwegomba mukupisa kwakanyanya kana kuderera kwekushisa nharaunda, kunyanya iyo inoxidability mukupisa kwakanyanya.
1.kushanda
2.High tensile simba, kutsungirira simba, zvinokambaira simba uye kuputika simba pa700 ℃.
3.High inoxidability pa1000 ℃.
4.Steady mechanical performance mukupisa kwakadzika.
Iyo yakakwira tembiricha simba, yakanakisa corrosion kuramba uye kushanda pa700 ℃ zvivakwa zvakaita kuti ishandiswe munzvimbo dzakasiyana siyana dzepamusoro dzinodiwa.Inconel mamakisi akakodzera kushandiswa mukugadzirwa kwezvinhu zvinoshandiswa munzvimbo dzakaomarara senge turbocharger rotor & zvisimbiso, mota shafts yemagetsi submersible pombi pombi, majenareta ehutsi, machubhu ezvinopisa kupisa, pfuti inorira inodzvinyirira inoputika baffles uye mune muchina pfuti. , black box recorder mundege etc.
