1. Kukana kwabwino kwambiri kwa media ambiri owononga amadzimadzi komanso mlengalenga wotentha kwambiri.
2.Mkulu mphamvu.kukhazikika bwino kwa metallurqical, komanso mawonekedwe abwino opangira
3.kukana kwambiri kwa oxidizina mankhwala ndi kutentha kwapamwamba kwa oxidizina mpweya
4 Kukana kwabwino kustresscorrosion cracking m'malo okhala ndi chloride komanso mayankho a sodium hvdroxide
Kukaniza kwa alloy ku mpweya wokhala ndi sulfure kumapangitsa kukhala chinthu chowoneka bwino pakugwiritsa ntchito monga mayunitsi opangira malasha, zoyatsira ndi ma ducts opangira sulfuric acid, ng'anjo yamafuta a petrochemical processing, recuperators, incinerators, ndi zida zamagalasi vitrification pakutaya zinyalala za radioactive.Mumitundu yosiyanasiyana yamadzi otentha kwambiri, aloyi 690 imawonetsa kutsika kwa dzimbiri komanso kukana kwambiri kupsinjika-kusweka kwa dzimbiri.Choncho.aloyi 690 chimagwiritsidwa ntchito machubu jenereta nthunzi, baffles, tubesheets, ndi hardware kupanga mphamvu nyukiliya.
