Hastelloy C4 Sheet

Hastelloy C4 sheet is a nickel-molybdenum alloy with excellent resistance to corrosion and oxidation. Its composition includes molybdenum, chromium, tungsten, carbon, manganese, silicon and iron for enhanced heat resistance and strength. This sheet has good fabricability, machinability and superior weldability compared to other alloys; moreover, it excels in reducing environments like sulfuric acid. Hastelloy C4 is widely used in chemical process equipment that handles high-temperature corrosive gases or liquids at pressures above the limits of most other stainless steels.

Hastelloy C4 Sheet is a nickel-molybdenum alloy with excellent resistance to localized corrosion and good resistance to oxidizing and sulfidic atmospheres. It has outstanding qualities such as high ductility, superior workability, and weldability. Due to its molybdenum content, the material is highly resistant to pitting and crevices corrosion. It also offers excellent stress-corrosion cracking resistance in chloride-containing environments like seawater or salt spray. Common uses of Hastelloy C4 sheet include storage tanks for chemical compounds, chemical processing equipment components (pumps, valves), plumbing components in marine applications, piping systems exposed to hydrogen sulphide-based gases and solutions, etc.
