I. Overview of Alloy 59(N06059) nickel-based alloy:
Alloy 59 (N06059) is a nickel-chromium-molybdenum alloy withextremely low silicon and carbon content, excellent corrosion resistance andhigh mechanical strength. It also has the following characteristics:
1. It has excellent resistance to pitting,crevice corrosion and stress corrosion cracking.
2. It has excellent corrosion resistance toinorganic acids, such as nitric acid, phosphoric acid, sulfuric acid andhydrochloric acid, especially the mixture of sulfuric acid and hydrochloricacid.
3. Excellent resistance to the corrosion ofvarious inorganic acid mixed solutions.
4. It has good corrosion resistance invarious concentrations of hydrochloric acid solutions up to 40 ° C (104 ° F).
5. Has good processability and weldability,no cracking sensitivity after welding.
6. Manufacturing certification of pressurevessels with wall temperature of -196 ~ 450 ℃.
7. Certified by the American Society ofCorrosion Engineers NACE standard (MR-01-75) to meet the highest standard levelVII for use in acid gas environments.
