HASTELLOYC4yog ib qho alloy uas muaj nickel, chromium, thiab molybdenum. Nws yog qhov tseem ceeb tshaj plaws uas muaj ntau yam alloy rau kev tiv thaiv corrosion. Cov alloy no qhia tau hais tias tsis kam mus rau qhov tsim ntawm grain ciam precipitates thaum raug vuam kub, ua rau nws haum rau ntau yam tshuaj txheej txheem kev siv nyob rau hauv nws welded xeev. Tsis tas li ntawd, AlloyC4Cov khoom pov thawj zoo heev rau pitting, kev nyuaj siab-corrosion tawg, thiab oxidizing cua mus txog 1900 ° F. Nws muaj qhov tshwj xeeb tiv thaiv rau ntau qhov chaw ntawm cov tshuaj lom neeg.
