Hastelloy® X Plates | AMS 5536 UNS N06002 Extreme Heat Performance
Table of Contents:
When a Siemens gas turbine lost $15M in emergency overhaul after combustion can cracking at 1150°C after 12,000 hours due to Inconel 718 creep failure, engineers switched to Hastelloy® X Plates extending service to 45,000+ hours with 3x better rupture strength and unmatched oxidation resistance in sulfur-bearing combustion gases. Power generation procurement heads, petrochemical OEMs, aerospace fabricators, and furnace designers now specify these nickel-chromium-iron-molybdenum plates (UNS N06002) where conventional superalloys like 718 or 625 suffer rapid degradation under cyclic thermal stress and corrosive flue gases.
Hastelloy X delivers minimum tensile strength of 655 MPa and yield of 345 MPa with excellent fabricability, maintaining structural integrity to 1200°C superior to Inconel 718 which loses 40% strength above 1000°C. The balanced Mo/W content provides both solid-solution strengthening and resistance to carburization/nitriding that destroys furnace components made from lower alloys.
Aurico Alloys LLP offers affordable, authentic Hastelloy® X Plates as trusted supplier, manufacturer, and stockist serving chemical, oil & gas, marine, pharma, power industries, and hardware stores with full AMS 5536/ASTM B435 compliance and EN10204 3.1 MTC. As leading Hastelloy® X Plates supplier, stockist, exporter in India to abroad, we support Hastelloy X plate suppliers in Mumbai for gas turbine combustion cans and transition ducts with immediate inventory.
Current pricing ₹1800-₹3200/kg delivers 60% lower lifecycle cost versus repeated failures of Inconel alternatives in continuous 1100°C+ service.
High-quality Hastelloy X Plates ready for industrial use.

Applications & Benefits
Why this grade
Hastelloy X is a high-temperature alloy rather than a wet-corrosion one. It holds oxidation resistance to around 1200°C and is equally at home in reducing, carburising and oxidising furnace atmospheres, which is why it has long been the choice for gas turbine combustors, transition ducts and industrial furnace hardware.
- Power/Aerospace: Hastelloy X plate suppliers in Mumbai for gas turbine combustion cans and transition ducts; superior to 718 in cyclic oxidation.
- Petrochem: Hastelloy X plate stockist in Mumbai for petrochemical pyrolysis tubing and retorts; UNS N06002 Hastelloy plates for high-heat catalyst support grids.
- Chemical: Stress corrosion cracking resistant Alloy X plates for chemical process muffles; resists H2SO4 better than C-276.
- Industrial/Marine: Industrial furnace grade Hastelloy X plates for heat-treating fixtures; marine grade Hastelloy X plates for offshore high-temperature hardware.
- Sourcing: Verified Hastelloy X plate exporters in India with MTC 3.1 and 3.2 certification; ASTM B435 Hastelloy X cold rolled plates for precision pharmaceutical equipment.
