When an aerospace turbine manufacturer struggled to find a material combining high temperature strength with oxidation resistance, Hastelloy X Sheets emerged as the trusted solution delivering exceptional performance in harsh chemical, oil & gas, marine, pharmaceutical, and power environments. Aurico Alloys LLP supplies these world-class sheets to engineers and procurement heads seeking superior durability and compliance.

Hastelloy X (UNS N06002, ASTM B435, ASME SB435) is a nickel-chromium-iron-molybdenum alloy strengthened against heat and corrosion up to 2200°F. Its balanced composition gives it excellent oxidation, carburization, and nitriding resistance, as well as notable resistance to chloride-induced stress corrosion cracking. This combination makes Hastelloy X a favorite for combustion zone components in gas turbines, chemical reactor parts, and industrial furnace equipment.

Aurico Alloys LLP offers Hastelloy X Sheets in a wide range of thicknesses and finishes, backed by comprehensive ASTM and ASME certification and full mill test certification to meet stringent international standards. Immediate availability and custom cutting ensure rapid delivery to support critical OEM projects and maintenance activities.

Choosing Aurico’s Hastelloy X Sheets means investing in a premium alloy designed to withstand extreme thermal and corrosive conditions, optimizing operational reliability and reducing costly downtime.

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.

  • Gas turbine engine components: combustor cans, transition ducts, spray bars, flame holders
  • Industrial furnace rolls, retorts, muffles, and heating elements
  • Chemical processing reactors, heat exchangers, and piping in oxidizing environments
  • Aerospace: jet engine components requiring high strength and oxidation resistance
  • Oil & gas: refinery equipment and components exposed to high temperature and corrosive atmospheres
  • Power generation components facing thermal and chemical exposure
