Hastelloy G-35 is an upgraded product of G-30. It has excellent corrosion resistance in the wet phosphoric acid production environment widely used in fertilizer manufacturing. In this environment, its performance is far better than G-30 and stainless steel. . It can also resist localized corrosion in media containing chloride and chloride ion stress corrosion cracking. The high chromium content makes it very resistant to corrosion by nitric acid and other oxidizing acids such as nitric acid-containing mixtures. The higher molybdenum content gives it moderate corrosion resistance to reducing acids.

The high chromium content makes it very resistant to corrosion by nitric acid and other oxidizing acids such as nitric acid-containing mixtures. The higher molybdenum content gives it moderate corrosion resistance to reducing acids. Unlike other nickel-chromium-molybdenum alloys, Hastelloy G-35 is highly resistant to corrosion by the dealloying element of hot sodium hydroxide.

application:

Wet phosphoric acid production evaporators, pickling equipment using nitric acid and hydrofluoric acid, caustic soda neutralization systems, and chemical systems involving nitric acid and chlorides.
