I-alloy 718 yaqale yaphuhliswa kwishishini le-aerospace kodwa amandla ayo agqwesileyo kunye nokumelana nomhlwa kuye kwaqatshelwa lishishini leoli kwaye ngoku isetyenziswa kakhulu kule ndawo.

I-alloy 718 yi-alloy ye-nickel-chromium enokuthi iphathwe ubushushu ukunika amandla aphezulu, ukuxhathisa okulungileyo kwe-corrosion, ukukhululeka kokwakheka kunye nokunokuthi kufakwe i-welded kunye nokuchasana okulungileyo kwi-strain age cracking. I-alloy ingasetyenziswa kumaqondo obushushu ukuya kuma-700ºC.

I-alloy 718 yoshishino lwe-oyile iphathwa ubushushu kangangokuba ubunzima abudluli kwi-40HRC eyona nto iphezulu evunyelwe yi-NACE MR-01-75 / ISO 15156: 3 ukukhusela uxinzelelo lwe-corrosion cracking. Ezona zicelo ziphambili kulo mmandla ziiVave kunye netyhubhu echanekileyo.

I-alloy 718 ye-aerospace kunye nokuveliswa kwamandla kunyangwa ubushushu ukunika amandla aphezulu kunye nokumelana nokunyuka okuphezulu kunye namaxabiso obunzima obuqhelekileyo obudlula i-42HRC. Ezona zinto zisetyenziswayo zizinto ezisetyenziswa kwiiinjini zegesi, iinjini zeenqwelo-moya, iziqhoboshi kunye nolunye usetyenziso lwamandla aphezulu.
