Alloy 686 is one-phase, austenitic Ni-Cr-Mo-W alloy inopa yakasarudzika corrosion-resistant munzvimbo dzakaomarara.Iyo yakakwira nickel (Ni) uye molybdenum (Mo) inopa kumira kwakanaka mukuderedza mamiriro, uye yakakwira chromium (Cr) inopa kuramba kune oxidizing midhiya.Molybdenum (Mo) uye tungsten (W) inobatsira kuramba kune corrosion yenzvimbo senge gomba.Simbi (Fe) inodzorwa zvakanyanya kuwedzera zvivakwa.Low kabhoni (C) inobatsira kudzikisira kunaya kwemuganho wezviyo kuchengetedza ngura-kusagadzikana munzvimbo dzakakanganiswa nekupisa kwemajoini akasungwa.

1.Kupikisa kwakanaka mukuderedza mamiriro ezvinhu;
2.Kuramba kwakanaka kune oxidizing media;
3.Resistance kune general, pitting uye crevice corrosion inowedzera.
hukasha midhiya mukugadzirisa makemikari, kudzora kusvibiswa, kugadzirwa kwemapepa uye mapepa, uye kushandiswa kwemarara.
