Hastelloy G-30 inopa yakakwira corrosion kuramba kune kutengeserana phosphoric asidhi uye dzakawanda dzakaoma nharaunda dzine yakasimba oxidizing asidhi senge nitric acid/hydrochloric acid, nitric acid/hydrofluoric acid uye sulfuric acid.
Inogona kudzivirira kuumbwa kwezviyo muganho kunaya mune welding kupisa kwakakanganiswa zone, kuitira kuti igone kuchinjika kune akawanda marudzi emakemikari ekushanda mamiriro muwelding state.
