At Ganpat Industrial, Incoloy 800 Washers are manufactured from mill certified UNS N08800 flat stock and coil, an alloy also known in the market as Alloy 800 or WNR 1.4876, with every piece blanked and finished in house to the composition standards set by ASTM A240 and ASME SA240. Built on an iron-nickel-chromium base, this material resists deformation and retains its dimensional integrity through repeated thermal cycles far better than conventional stainless steel washers a property that makes it the go-to choice wherever joints face furnace temperatures, carburizing environments or continuous heating-cooling stress without any margin for a fastener to loosen or corrode away. These washers are routinely supplied for furnace heat-treatment lines, ethylene cracker units, nuclear fuel handling systems and high-temperature flange connections, applications where a standard stainless washer would typically oxidize or lose strength within a matter of months. Each batch shipped is backed by documentation traceable to its original mill heat number, giving buyers full visibility into the source coil. With more than twenty-five years of manufacturing experience based out of Mumbai, Ganpat Industrial Corporation supplies both standard catalogue sizes and custom drawing-based washers to industrial buyers across India, the GCC, Europe and Southeast Asia.

All washer profiles are produced on site, letting buyers cover their entire fastening requirement through a single order.

As an Incoloy 800 Washers Supplier in India, we test every batch for hardness, dimensions and material grade before dispatch.

Each incoming heat is lab tested to confirm it falls within the ASTM A240 / ASME SA240 composition range before production begins.

Each production lot is validated in the solution-annealed condition, holding to the minimum values set by ASTM B408.

Buyers can request hardness verification through any of the three scales below, based on the accuracy their application demands.

Figures below cover continuous exposure in air for reducing or carburizing environments, reach out to our team for application-specific guidance.

These washers are used across industries where bolted joints must retain tension despite continuous heating and cooling.

The same Fe-Ni-Cr alloy is recognized under different designations depending on which country’s standards a buyer follows.

As an Incoloy 800 Washers Manufacturer in India, we blank, form and finish every washer in house.

Each finish suits a different type of joint, so buyers can pick based on where the washer will actually be installed.

As an Incoloy 800 Washers Supplier in India, we pack every order with moisture protection for safe export shipping.

These documents accompany shipments to keep customs clearance and quality checks straightforward on the buyer’s end.

Under prolonged clamp load at high temperature, this property determines how long a washer holds its shape before it begins to deform.
