Special Metals

Thermal Processing

Engineered for Extreme Heat

With high-temperature strength and resistance to corrosion by furnace atmospheres, the INCOLOY®, INCONEL® and NIMONIC® alloys are ideal for furnace components.

Serving Thermal Needs

in Multiple Applications

For refining, processing and other areas, Special Metals makes the specialty alloys needed for thermal processing projects.

Popular Thermal Applications

We supply alloys for radiant tubes, muffles, retorts, belts and hearths and for the jigs and carriers that support the work through the heat-treatment processes.

Seamless Tubing Solutions

KOTHERM® and NIOTHERM® wires and INCOTHERM™ alloy seamless tubing are used for thermocouples where high-temperature corrosion resistance and strength are required.

Designed for Punishing Heat

INCONEL® alloy HX is a nickel-chromium-iron-molybdenum alloy with outstanding strength and oxidation resistance at temperatures up to 2200°F.
