Ganpat Industrial Corporation punches and precision-finishes Hastelloy X Washers from certified Alloy X flat stock at our Mumbai facility. This nickel-chromium-iron-molybdenum alloy keeps its strength where most fasteners soften, staying stable under repeated heating and cooling cycles up to 1200°C. Gas-turbine combustor rings, furnace baskets and catalyst-support grids all depend on that same oxidation resistance. A washer that scales or sheds material under heat leaves a joint loose within a single shutdown cycle. Every batch we dispatch carries full heat traceability, dimensional reports and PMI verification. Ganpat Industrial has supplied specialty alloy fasteners for over two decades from Mumbai, reaching buyers across India, the UAE, Europe and the wider Middle East from a standing rack inventory.
