Material Notes: Developed as a lower cost alternative to Hastelloy C-276 for use by producers of sour gas. Improved corrosion resistance compared to G-3 in service with high hydrogen disulfide concentrations in combination with carbon dioxide, chloride, etc. Its corrosion resistance at elevated temperatures falls between G-3 and C-276 in 15% HCl and in hydrogen sulfide sress corrosion cracking tests. G-50 alloy lends itself to consistent methods of manufacture of tubular products.
