What is Hastelloy C276 Washer?
Hastelloy C276 washers are corrosion-resistant fastening washers made from Hastelloy C-276, a nickel-molybdenum-chromium alloy with iron. They are engineered for outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking in both oxidizing and reducing environments. These washers are used in extremely corrosive chemical and process industries where standard alloys fail.
Applications of Hastelloy C276 Washer
- Chemical Processing – Fasteners in reactors, piping, and tanks handling chlorides, acids (including hydrochloric and sulfuric), and oxidizing media.
- Pollution Control & Waste Treatment – Used in scrubbers, effluent treatment plants, and corrosive waste systems.
- Pulp & Paper – Components in digesters and bleach plants exposed to harsh chemicals.
- Oil & Gas – Downstream and chemical injection systems where sour or chloride-bearing fluids exist.
- Marine & Desalination – Critical hardware in seawater/brine systems and desalination equipment.
- Research & Specialty Plants – Corrosion-critical lab and pilot plant equipment.
Common Uses of Hastelloy C276 Washer
- Seating washers under bolts/nuts in highly corrosive process equipment.
- Washers used in flanges, pumps, and valve assemblies in aggressive chemical environments.
- Fastening hardware for heat exchangers and reactors handling mixed oxidizing and reducing chemistries.
- Washers in desalination, brine handling, and seawater cooling systems.
- Used wherever long life and minimal maintenance in corrosive service are required.
- Specialty chemical and pilot plants with highly corrosive reagents.
