Hastelloy® G-30 ndi mtundu wa nickel-chromium-iron-molybdenum-copper alloy G-3.Ndi chromium yapamwamba, cobalt yowonjezeredwa ndi tungsten, G-30 imawonetsa kukana kwa dzimbiri kwapamwamba kuposa ma nickel ndi aloyi opangidwa ndi chitsulo mu malonda a phosphoric acid komanso malo ovuta omwe ali ndi ma oxidizing acid.Kukaniza kwa aloyi pakupanga malire a tirigu kumalowa m'dera lomwe limakhudzidwa ndi kutentha kumapangitsa kuti likhale loyenera kugwiritsidwa ntchito pazinthu zambiri zamakina opangira mankhwala mumtundu wa welded.

Hastelloy G-30 imapereka kukana kwamphamvu kwa kutu ku malonda a phosphoric acid ndi malo ambiri ovuta okhala ndi ma oxidizing amphamvu monga nitric acid/hydrochloric acid, nitric acid/hydrofluoric acid ndi sulfuric acid.
Iwo angalepheretse mapangidwe mbewu malire mpweya mu kuwotcherera kutentha bwanji zone, kotero kuti azolowere mitundu yambiri ya zinthu mankhwala ntchito mu dziko kuwotcherera.
•Zida za phosphoric acid•Zochita zokolola
•Zida za sulfuric acid•Petrochemical mankhwala
•Zida za nitric acid•Kupanga feteleza
•Kukonzanso mafuta a nyukiliya•Kupanga mankhwala ophera tizilombo
•Kutaya zinyalala za nyukiliya•Kuchotsa golide
