HASTELLOYC4mangrupa alloy diwangun ku nikel, kromium, jeung molybdenum. Hal ieu kacida dianggap salaku alloy paling serbaguna pikeun merangan korosi. alloy Ieu nunjukkeun lalawanan ka formasi wates sisikian precipitates nalika subjected ka panas las, sahingga cocog pikeun sagala rupa aplikasi prosés kimiawi dina kaayaan dilas na. Sajaba ti éta, AlloyC4némbongkeun résistansi anu luar biasa pikeun ngadu, retakan-korosi stres, sareng atmosfir pangoksidasi dugi ka 1900 ° F. Éta gaduh résistansi luar biasa pikeun rupa-rupa lingkungan kimia.
