Hastelloy B3 Washer

What is Hastelloy B3 Washer?

Hastelloy B3 washers are high-performance corrosion-resistant washers made from Hastelloy B3, a nickel-molybdenum alloy designed to offer exceptional resistance to strong reducing environments. This alloy provides superior stability and improved thermal resistance compared to earlier Hastelloy grades like B2. These washers perform exceptionally well in hydrochloric acid, hydrogen chloride gas, sulfuric acid, acetic acid, and other aggressive reducing chemicals, even at varying temperatures.

Applications of Hastelloy B3 Washer

  • Chemical Processing – Ideal for equipment handling pure and contaminated hydrochloric acid, sulfuric acid, or hydrogen chloride gas.
  • Acid Production & Regeneration – Suitable for acid concentration units, HCl recovery systems, and reactors.
  • Pharmaceutical & Fine Chemicals – Used in processing systems involving strong reducing agents.
  • Petrochemical & Refining – Applied in process units exposed to reducing environments and chloride-rich media.
  • Pumps, Valves & Piping – Washers for sealing and fastening components in corrosive fluid-handling equipment.
  • Research Laboratories – Used for corrosive experiment setups and high-purity chemical systems.

Common Uses of Hastelloy B3 Washer

  • Fastening washers in systems exposed to highly reducing acids and chemical media.
  • Washers for chemical reactors, transfer lines, and acid-resistant equipment.
  • Components in pumps, heat exchangers, and mixers used in corrosive processes.
  • Washers for piping systems transporting aggressive reducing fluids.
  • Used in high-corrosion, long-life fastening systems where downtime must be minimized.
  • Special chemical plants handling anhydrous or mixed strong reducing agents.
