Hastelloy washers offered by Sheetal Fasteners are durable and can perform optimally in harsh conditions. These washers are manufactured from Hastelloy alloys which are nickel-molybdenum based and are highly resistant to corrosion and are strong. Our Hastelloy washers are suitable for chemical processing, aerospace, and high-temperature applications because they provide secure sealing and spacing in challenging environments.
Some of the features of Hastelloy washers includes high resistance to corrosive environments such as strong acids and chlorides. They possess high tensile strength and exhibit good resistant to fatigue and wear and tear and can work effectively in high temperature and pressure. Hastelloy washers do not corrode and are also resistant to oxidation and stress corrosion cracking, which makes them ideal for chemical processing, aerospace, among other industries. This makes them to be reliable and have a long lasting performance due to their strong characteristics.
