Hastelloy G-3 Seamless Pipe & Tube Supplier

As a leading nickel alloy supplier, we produce high-quality Hastelloy G-3 seamless pipes.
Hastelloy G-3 is a nickel-based alloy seamless pipe that is widely used in the chemical, petroleum, energy and environmental protection fields for its excellent corrosion resistance and high temperature performance.
The manufacturing process of Hastelloy G-3 seamless pipes strictly follows international standards to ensure that the material structure is uniform and defect-free. We use cold rolling or cold drawing processes to ensure high dimensional accuracy and excellent surface finish of the pipe. To further verify the reliability and safety of the product, each Hastelloy G-3 seamless pipe undergoes a rigorous hydrostatic test to ensure that it has no leakage or deformation under high pressure conditions and meets the needs of long-term stable operation.

Chemical Composition of Hastelloy G-3

*Chemical Composition According to ASTM B622

The chemical composition of Hastelloy G-3 seamless pipes has been carefully designed, mainly containing key elements such as nickel, chromium, molybdenum, and iron, while copper and tungsten are added to enhance corrosion resistance in specific environments. The high nickel content ensures the stability of the material in reducing media, while the synergistic effect of chromium and molybdenum significantly improves the ability to resist pitting and crevice corrosion, especially in harsh environments containing chlorides, sulfuric acid and phosphoric acid.
