Tsananguro yeInconel 718

Inconel 718 Kunyorera

Inconel 718 ine yakanaka ngura kuramba uye yang kuramba mujet injini uye gasi turbine mafomu. Iyo alloy inoshandiswa kune zvikamu zvinoda kukwikwidza kwakadzika uye kushushikana kutsemuka kusvika 1300 ° F (704 ° C) uye oxidation kuramba kusvika ku1800 ° F (982 ° C). Kunyangwe pane tembiricha yakaderera, Kugadzira Inconel 718 ine yakanakisa tensile uye kukanganisa zvivakwa. AMS 5662 inoda simba regoho ≥ 150,000 psi patembiricha yemukati.

Inconel 718 machinability

Inconel 718 inorondedzerwa semvura inonaya ichiomesa alloy iyo inogona kuve zera rakaomeswa nekupisa kurapwa. Chimiro chezviyo chinochengetedza austenite pane ese tembiricha. Mhinduro dzakasiyana siyana uye kurapa kwekukwegura zvinoshandiswa panguva iyi yekurapa kwekupisa kugadzirisa kwenguva pfupi-kana refu-tembiricha yakakwira-tembiricha mega zvimiro.
