1. What is Alloy G-3?

Alloy G-3(UNS N06985), or Hastelloy G-3, is a nickel-based alloy engineered for superior corrosion resistance in reducing acids, including phosphoric, sulfuric, and hydrochloric acids. With high molybdenum (6.0-8.0%) and copper (1.5-2.5%), Alloy G-3 material resists pitting and stress corrosion cracking, making Alloy G-3 plate ideal for chemical reactors and sour gas environments. Compared to Alloy C276, Alloy G-3 offers improved weldability and resistance to weld-zone corrosion in reducing conditions.

How Does Alloy G-3 Compare to Alloy G-30?

Alloy G-3(UNS N06985) excels in reducing acids with better weldability, while Alloy G-30 (UNS N06030) is optimized for phosphoric acid due to higher chromium. Alloy G-3 plate is preferred for oil and gas applications.
