PM Industries manufactures, supplies, and stocks HS160 Haynes HR-160 Superalloy Sheet Plate (UNS N12160) in a range of thicknesses and sizes. HS160 is the sheet product designation for Haynes HR-160, a cobalt-nickel-chromium alloy with a significant silicon addition that sets it apart from other high-temperature sheet alloys. While most nickel and cobalt superalloys rely primarily on chromium for oxidation protection, HR-160's silicon content provides an additional mechanism for sulfidation resistance that chromium alone doesn't deliver. That combination makes it the preferred sheet alloy for applications where both oxidation and sulfidation are service concerns, particularly in waste incineration, industrial furnace, and flue gas environments where sulfur-containing gases are present alongside high heat.

In sheet and plate form, HR-160 is fabricated into liner panels, furnace wall components, grate elements, and hot-section sheet metal structures where the environment combines high temperature with sulfur-containing or mixed gas chemistries that would attack standard nickel alloys. The silicon addition that provides the sulfidation resistance also makes HR-160 somewhat more resistant to thermal cycling than purely chromia-forming alloys, supporting longer service life in equipment that cycles temperature repeatedly during operation.

Sulfidation resistance is the property that most consistently drives HS160 specification over competing high-temperature sheet alloys. In industrial environments where combustion gases, waste streams, or process chemistries introduce sulfur alongside high heat, most standard nickel alloys corrode significantly faster than their oxidation resistance ratings would suggest. Sulfur attacks grain boundaries, disrupts oxide scale formation, and causes rapid internal corrosion. HR-160's silicon addition creates a silicon-enriched zone at the alloy surface that resists that sulfur penetration mechanism, giving the alloy meaningful additional life in those environments compared to alloys without silicon enrichment.

Waste incineration applications are where this distinction matters most in sheet form. Incinerator grate components, afterburner liner panels, and combustion chamber sheet metal are exposed to combustion products that contain sulfur compounds from waste materials alongside temperatures that stress most alloys. HS160 sheet handles that combination better than standard nickel alloys and comparably to the more expensive platinum group metal-enhanced materials for less severe waste incineration service.

Industrial furnace liner applications benefit from the combined oxidation and sulfidation resistance where furnace atmospheres contain sulfur from fuel combustion or process materials. Batch and continuous furnaces in metal processing, heat treatment, and chemical processing that use sulfur-bearing fuels or process materials with sulfur content can attack standard nickel alloy furnace liners faster than expected. HS160 liner panels provide extended service life in those conditions.

Thermal cycling resistance is good. The silicon addition in HR-160 also benefits scale adhesion during thermal cycling, similar in mechanism to lanthanum additions in other alloys. The protective surface layer holds up better through repeated heating and cooling cycles than in alloys that rely solely on chromia scale formation, which reduces the progressive surface consumption that cycling causes in less stable alloys.

Sheet and plate are available in the solution-annealed condition across a range of thicknesses and sizes with material certification to applicable Haynes and relevant specifications. Contact PM Industries for thickness, width, length, and pricing.
