Hastelloy Alloy C-276 Ring Type Joint Gasket

For the most time, ring joint gasket materials like SS304, SS316 can be used. But when the ring joint gaskets need contact very critical service, materials like Monel 400, Alloy C-276 will be used. For us Ningbo Sunshine, we can offer all range of steel materials for your special need.

Welcome to Know Hastelloy Alloy C-276 Ring Type Joint Gasket

Special alloys gasket like Hastelloy alloy C-276 ring type joint gasket is needed In some environments. This gasket has excellent corrosion resistance in a wide range of severe environments. It is widely used in the most severe environments such as chemical processing, pollution control, pulp and paper production, industrial and municipal waste treatment, and recovery of sour natural gas.

As Alloy C-276 nickel alloy has good high temperature strength and moderate oxidation resistance, so the gasket can bear high temperature. My company can offer you the best high quality special alloy material ring joint gasket. Other materials like Monel 400, SS316, SS304 also can be offered.


Hastelloy alloy C-276 ring type joint gasket can be used in pollution control stack liners, ducts, dampers. It is also suitable for flue gas desulfurization systems, chemical processing components, pulp and paper production.

What are the Characteristics of Hastelloy Alloy C276?

  • It has low carbon content which minimizes grain-boundary carbide precipitation during welding to maintain resistance to corrosion in heat-affected zones of welded joints.
  • The high nickel and molybdenum contents of Hastelloy Alloy C276 provide good corrosion resistance in reducing environments.
  • It has exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.
  • It owns good resistance to localized corrosion such as pitting and stress-corrosion cracking
  • Hastelloy Alloy C276 has excellent corrosion resistance in reducing environments.
