Hastelloy B2 Washer

What is Hastelloy B2 Washer?

Hastelloy B2 washers are high-performance washers manufactured from Hastelloy B2, a nickel-molybdenum alloy designed for excellent resistance to reducing environments. They provide outstanding protection against hydrochloric acid, hydrogen chloride gas, sulfuric acid, acetic acid, and other strong reducing chemicals. These washers are used in environments where conventional stainless steels or standard alloys fail due to severe corrosion.

Applications of Hastelloy B2 Washer

  • Chemical Processing – Used in equipment handling strong reducing acids such as HCl, H₂SO₄, and hydrogen chloride gas.
  • Acid Production Plants – Ideal for acid regeneration units and acid concentration systems.
  • Pharmaceutical & Specialty Chemicals – For reactors, vessels, and agitation systems exposed to aggressive reducing chemicals.
  • Petrochemical Industry – Used in processing units where chloride-containing and reducing media are present.
  • Pump & Valve Assemblies – Suitable for components in corrosive fluid transfer systems.
  • Research Laboratories – Used for experimental setups involving highly corrosive reducing agents.

Common Uses of Hastelloy B2 Washer

  • Fastening washers in systems dealing with strong reducing acids.
  • Washers used in chemical reactors, storage tanks, and acid-handling equipment.
  • Hardware for pumps, mixers, and heat exchangers exposed to corrosive reducing media.
  • Used in piping systems transferring aggressive reducing chemicals.
  • Fastener components where long-term corrosion resistance in reducing environments is mandatory.
  • Special chemical processing plants handling pure, anhydrous, or contaminated reducing chemicals.
