Hastelloy C4 Coil is an alloy of nickel, molybdenum, chromium and iron. It is designed for superior corrosion resistance under severe temperature conditions. Specifically, it is highly resistant to stress corrosion cracking and pitting in reducing and oxidizing environments. Adding tungsten also improves its heat resistance properties, making it a suitable choice in high-temperature industrial applications.

Hastelloy C4 Coil is an alloy of nickel-chromium-molybdenum designed for extreme resistance to corrosion and oxidation. It retains superior strength and excellent stress rupture and creep properties over various temperatures. Hastelloy C4 Coil mainly produces chemical process components, such as heat exchangers, pipelines, pumps, valves and flanges. In addition to that, it is also found in applications such as environmental protection systems where reliable chloride stress-corrosion cracking resistance is required.
