Nimonic 115 Plates | BS HR 4 Fuel, Salt & Creep-Resistant Alloy for 1000°C Service
Table of Contents:
When a coastal combined-cycle plant near Mumbai saw its gas turbine blades and exhaust components losing metal at 980–1000°C due to hot corrosion from vanadium‑rich fuel oils and salt-laden intake air, each unplanned outage wiped out crores in generation and pushed maintenance teams toward increasingly frequent blade changes. After switching critical hardware to Nimonic 115 Plates, a nickel‑chromium‑cobalt superalloy with molybdenum, aluminum and titanium strengthening, creep-rupture tests reported strength to about 1010°C and case studies showed blade life increasing by more than 2–3× under similar duty, with oxide scales and section thickness staying stable across thousands of thermal cycles.
Nimonic 115 (W.Nr. 2.4636) is a precipitation-hardening nickel‑chromium‑cobalt alloy designed for high strength and creep resistance at temperatures up to roughly 1010°C, combining strong gamma‑prime strengthening with excellent oxidation and corrosion resistance in aggressive gas‑turbine and process environments. The alloy has documented tensile strength around 1300 MPa and 0.2% yield strength near 850 MPa in precipitation-hardened condition, alongside 25% elongation, giving both toughness and high load capacity for rotating and static parts.

Stock & Product Availability
Mumbai buyers search for BS HR 4 Nimonic 115 plates supplier and stockist in Mumbai India for turbine parts, boiler hardware and high‑temperature fabrication, and many distributors offer both hot rolled and cold rolled plates with mill test certificates. OEMs and fabricators also seek Nimonic 115 hot rolled vs cold rolled plates availability in Mumbai to balance formability, surface finish and lead time for combustion parts and reactor shells.
Industrial fabricators value Nimonic 115 alloy plate cut-to-size service for industrial fabrication because complex baffle, shield and flange shapes can be water‑jet or laser‑cut from plate, minimizing waste and fabrication time.

Applications & Benefits
Why this grade
Nimonic 115 is the strongest of the wrought Nimonic series, taking blade service to roughly 1000°C. It is ordered where nothing lower in the range will hold the stress, and it is correspondingly the most difficult of the family to work and to weld.
- Chemical Industry & Pharma: Buyers search for Nimonic 115 corrosion resistant plates for chemical reactors in Mumbai and high-temperature Nimonic 115 plates for pharmaceutical heat exchangers, because the alloy’s high nickel, chromium and molybdenum give strong resistance to high-temperature oxidizing and some acidic environments. Many projects specify nickel alloy 115 plate suppliers for acid-resistant chemical processing equipment where downtime must be minimized.
- Oil & Gas and Marine: Offshore EPCs look for Nimonic 115 plate stockist in Mumbai for offshore drilling tools and seawater corrosion resistant Nimonic 115 plates for marine exhaust systems, taking advantage of its hot corrosion resistance in salt-laden exhaust. Procurement teams also demand Nimonic 115 plate exporter for high-pressure oil and gas valves in severe HPHT conditions.
- Power Generation: Gas turbine and boiler designers specify Nimonic 115 creep resistant plates for industrial gas turbine components, and heat treated Nimonic 115 plates for power plant boiler parts Mumbai, leveraging the alloy’s documented creep resistance up to about 1010°C. Energy buyers benchmark Superalloy Nimonic 115 plate price per kg for energy sector projects India against expected increases in fired-hour life and reduced blade or liner replacements.
- General B2B & Export: Engineering buyers request chemical charts under keywords like Nimonic 115 plate equivalent grades and chemical composition chart and are served by suppliers listing W.Nr. 2.4636 and BS HR 4 in one datasheet. Mumbai’s C.P. Tank market promotes W.Nr. 2.4636 Nimonic alloy 115 plate dealers in C.P. Tank Mumbai to procurement heads wanting local stock with global certification.
