2.5mm Heat Resistant Nimonic 90 Plate Nickel Alloy Sheet for Gas Turbine Components

Explore precision-rolled 2.5mm Nimonic 90 nickel alloy plates designed for gas turbine components, combustion chambers, and high-stress aerospace environments with exceptional creep rupture strength up to 920°C.

The Nimonic 90 plate represents the benchmark in precipitation-strengthened nickel-base superalloys, strengthened by precise titanium and aluminum additions within a solid-solution nickel-chromium-cobalt matrix. Designed specifically to maintain metallurgical stability under continuous high thermal loads, this 2.5mm heat resistant sheet delivers outstanding resistance to creep-rupture, thermal fatigue, and hot corrosion.

Engineers and procurement teams select our nickel-base superalloy sheet for mission-critical gas turbine components where component failure is not an option. Through precision vacuum induction melting (VIM) followed by electroslag remelting (ESR) and tight multi-pass hot/cold rolling, we eliminate micro-segregation and ensure uniform grain sizing across the entire sheet surface.

• Exceptional Creep-Rupture Strength at Elevated Temperatures: Maintains reliable load-bearing capability and dimensional integrity under high mechanical stress up to 920°C, preventing high-temperature deformation in rotating and stationary hot-gas sections.
• Superior High-Temperature Oxidation & Hot Corrosion Resistance: The balanced 18–21% Chromium and Cobalt content forms an adherent, self-healing oxide scale that protects turbine components from severe oxidation and sulfidation attack.
• Stringent Microstructure & Ultrasonic Quality Control: Every batch of Nimonic 90 plate undergoes 100% non-destructive ultrasonic testing and micro-cleanliness evaluation to ensure zero internal voids, inclusions, or edge delamination.
• Excellent Fatigue & Thermal Shock Resistance: Resists micro-cracking caused by cyclic start-stop thermal gradients in aerospace power units and industrial gas turbine assemblies.

• Industrial Gas Turbines & Jet Engines: High-pressure turbine rotor discs, blade ring carriers, exhaust nozzles, and stator vane rings.
• Combustion & Afterburner Assemblies: Flame tubes, transition ducts, liner rings, and high-temperature baffle plates.
• Aerospace Fasteners & Springs: High-temperature springs, precision tie-rods, and turbine casing retaining bolts.
• High-Temperature Industrial Furnaces & Die Castings: Heat-treatment fixtures, hot-extrusion dies, and nuclear reactor core structural brackets.

• Integrated Superalloy Manufacturing Capacity: DLX operates complete in-house vacuum induction melting (VIM), electroslag remelting (ESR), forging, precision hot/cold rolling, and computerized continuous heat treatment lines with an overall monthly production capacity of 1,200 metric tons.
• Full Heat-Number Traceability & Inspection: Every shipment is accompanied by a genuine 3.1 Mill Test Certificate (MTC) providing full ladle chemical analysis, tensile testing, high-temperature creep verification, and dimensional reports.
• Custom Slitting, Leveling & Precision Shearing: Beyond standard stock sizes, we provide tailor-made 2.5mm sheets, strips, circular blanks, and laser/waterjet pre-cut profiles with strict burr-free edge finishing.
• Reliable B2B Global Supply & Export Packaging: Fast shipping with moisture-proof wrapping, seaworthy reinforced wooden cases, and custom palletizing engineered to prevent surface abrasion during long-haul transit.

A: Nimonic 90 is a precipitation-hardened alloy containing substantial amounts of Cobalt (15–21%), Titanium, and Aluminum. This unique composition delivers significantly higher creep-rupture strength and fatigue limits at operating temperatures between 650°C and 920°C than solid-solution alloys like Inconel 600 or standard stainless steels.

A: Optimal mechanical properties are obtained via a two-stage heat treatment:

1. Solution treatment: 1150°C for 2–3 hours followed by rapid air cooling or oil quenching.
2. Precipitation aging: 700°C for 16 hours followed by air cooling. We can deliver plates in either the annealed condition for cold forming or the fully heat-treated condition ready for direct machining.

A: Yes. In addition to standard sheet formats (1000×2000 mm, 1219×2438 mm), we provide precision waterjet, laser cutting, shearing, and custom edge leveling tailored to your specific technical drawings and CAD files.

A: We employ double-melting metallurgy (VIM + ESR) combined with multi-stage surface grinding, acid pickling, 100% surface eddy-current inspection, and ultrasonic flaw detection to ensure zero surface pitting, cracks, or non-metallic inclusions.
