Hastelloy C4(Ni – Cr – Mo)

1. Introduce – Ni – Cr – Mo alloy with good resistance to stress corrosion cracking and high temperature oxidizing atmospheres – Alloy with good resistance to hydrochloric acid, sulfuric acid, and chloride environments – Reduced C, Si content and addition of stabilizing element Ti for improved intergranular corrosion resistance – Low C, Si content: stable at 650 ~ 1040℃, improving intergranular corrosion resistance – UNS N06455 * High C content → Increased amount of carbide precipitation in the grain boundary → Reduced corrosion resistance * High C, Si...
