Description
Hastelloy G35
HASTELLOY® G-35® alloy (UNS N06035) was designed to resist “wet process” phosphoric acid (P2O5), which is used in the production of fertilizers. Tests in real-world solutions indi-cate that G-35 alloy is far superior to other metallic materials in this acid. It was also de-signed to resist localized attack in the presence of chlorides, since this can be a problem beneath deposits in evaporators used to concentrate “wet process” phosphoric acid.
