Hastelloy G30/UNS N06030/W. Nr. 2.4603 Sheet Tube Wire Bar

Overview

HASTELLOY G-30 alloy (UNS # N06030) is a nickel-chromium-iron material highly resistant to “wet process” phosphoric acid (P2 O5). also it is moderately resistant to chloride-induced localized attack, Furthermore, G-30® alloy is less susceptible to chloride-induced stress corrosion cracking than the stainless steels. 

As a result of its high chromium content, G-30alloy is also very resistant to other oxidizing acids, such as nitric, and mixtures containing nitric acid. It possesses moderate resistance to reducing acids, such as hydrochloric and sulfuric, as a result of its appreciable molybdenum and copper contents.

Corrosion Resistance

Hastelloy G30 is known for its exceptional corrosion resistance in oxidizing and reducing media. It resists attacks from hot and cold sulfuric acid solutions with concentrations up to 50%. It also resists nitric, acetic, and phosphoric acids, making it suitable for chemical processing industries. The alloy is also resistant to crevice and pitting corrosion in seawater and other chloride-containing environments.

Heat Treatment

 Hastelloy G30 can be heat-treated to achieve different strength levels. The solution-annealing treatment is the most common, which is carried out at a temperature range of 1070-1150°C. The alloy is then quenched in water or rapidly cooled in air. Another heat treatment process is the precipitation hardening method, which increases the hardness of the alloy.
