Nickel Alloys Washers

Nickel Alloy Washers Manufacturer, Supplier & Stockist

Unifit Fastener is a reliable manufacturer and supplier of high-performance nickel alloy washers, and they provide their products that satisfy the hard demands of the modern industries. We design our washers in a fine manner that will give them durability, classical dimensions, and excellent working conditions under extreme conditions. We have achieved customer satisfaction and a keen eye on quality and thus now form a favourable solution in the provision of nickel alloy fastening solutions in the world markets.

Nickel alloy washers are highly treasured due to their exceptional resistance towards corrosion, oxidation, and chemical exposure. These characteristics are what render them very useful in harsh conditions like the marine installations, petrochemical plants, power generation plants, and offshore installations. Popular brands like Nickel 200 Washers are characterized by being highly thermal and electrically conductive, with Nickel 201 Washers being more effective in high-temperature areas where carbon control is an important aspect. They are well-structured in mechanical strength such that they preserve tight joint integrity even when under high pressure and temperature to minimize the chances of leakage or breakage. Moreover, they are well welded and fabricable, hence suitable for the complex assemblies in industries.

In Unifit Fastener, quality control is a serious exercise in which all nickel alloy washers are subjected to in order to achieve uniform performance and reliability. Tests that are performed in-house by us are Positive Material Identification (PMI), pitting resistance tests, intergranular corrosion tests, micro and macro tests and flaring tests. These processes check the material composition, structural integrity, and corrosion resistance before the products find their way to our customers.

The integration of the best manufacturing processes with the highest standards of inspection enables Unifit Fastener to provide the best nickel alloy washers that provide better service and durability, safety, and longer value to the critical industrial works.
