Super alloys kana yakakwira performance alloys inowanikwa mune akasiyana maumbirwo uye ane zvinhu mumisanganiswa yakasiyana kuti uwane chaiyo mhedzisiro.Aya alloys ari emhando nhatu dzinosanganisira iron-based, cobalt-based uye nickel-based alloys.Iyo nickel-yakavakirwa uye cobalt-yakavakirwa super alloys anowanikwa sekukanda kana akagadzirwa-based alloys zvinoenderana nekuumbwa uye mashandisiro.
Super alloys ane yakanaka oxidation uye creep kuramba uye inogona kusimbiswa nekunaya kwemvura kuoma, kuoma-solution kuomesa uye kushanda kuomesa nzira.Ivo vanogona zvakare kushanda pasi peyakanyanya mechanical kushushikana uye tembiricha yepamusoro uye zvakare munzvimbo dzinoda kugadzikana kwepamusoro.
HASTELLOY (r) C276 isimbi yakashongedzwa isingadziviriri iyo inopesana nekusimudzirwa kwemuganhu wezviyo zvinoderedza kusagadzikana kwekuora.
Iri rinotevera dhetabheti rinopa mhedziso ye HASTELLOY(r) C276.
