When critical gas turbine pipes repeatedly failed under the combined assault of extreme heat and corrosive gases, process engineers turned to a breakthrough material: Nimonic 86 Round Bars. Designed for hostile cycles of heat, scaling, and chemical attack, these bars delivered the uptime, weldability, and high-temperature resilience that chemical, oil & gas, marine, pharma, and power teams demand. Today, procurement leads and OEM fabricators rely on Nimonic 86 for proven durability, traceability, and rapid delivery to safeguard high-value assets.

Nimonic 86 (W. Nr. 2.4961) stands apart as a solid-solution strengthened nickel-chromium-molybdenum alloy fortified by rare earth (cerium), cobalt, and titanium additions for maximum oxidation, scaling, and cyclic fatigue resistance at up to 1100°C. Unlike age-hardenable grades, its performance is built into its chemistry, making it a first-choice for burner liners, piping, and furnace hardware exposed to sustained thermal and corrosion cycles.
Available in diameters from 6mm to 200mm, Nimonic 86 round bars arrive in bright, rough-turned, or ground finish. These bars meet the Special Metals proprietary specification, BS HR201, and NACE MR0175 criteria, accompanied by full mill test certificates and global traceability. All Nimonic 86 Round Bars come with rapid shipment options and expert support for urgent projects and routine overhauls.
Industrial buyers prefer Nimonic 86 for affordable, high-quality, and authenticated supply protecting installations in chemical digesters, marine pump shafts, high-temp process tubes, and high-pressure energy lines, while achieving real savings through fewer shutdowns and repairs.
High-quality Nimonic 86 Round Bars ready for industrial use.
