Nimonic 90 Nickel Alloiy Strip

Product Introduction

Nimonic 90 alloy strip exhibits high tensile and creep strength, good oxidation and corrosion resistance, high fatigue strength, and good formability and weldability at temperatures ranging from 815 to 870°C.

We typically supply Nimonic 90 nickel alloy strip in common sizes, with from Thickness: 0.02mm - 16.0mm, Width: 5mm - 3000mm. Of course, we also offer other forms, such as Nimonic 90 bars, sheets, tubes, and wires, which can be customized to meet specific requirements.

Nimonic 90 alloy strip conforms to the mainstream industry standard BS HR202. For strips/plates, refer to AMS, ASTM, or national standard GB/T, which must be specified in the contract. Please get in touch with us for a technical specification sheet or a quote.

Practical Guide to Market Procurement

Supplier Selection (Equal Emphasis on Technology and Qualifications):

Process Capability Assessment: Prioritize manufacturers with vacuum induction melting + vacuum arc remelting or electroslag remelting capabilities. Directly inquire about their rolling and heat treatment processes and control levels for producing Nimonic 90 strip.

Qualifications and Certifications: For the aerospace industry, supplier certifications such as AS9100 and related NADCAP (e.g., heat treatment) are significant advantages.

Application Performance: Require successful case studies of supplying similar products in aerospace, gas turbine, and other fields.

Cost and Contract Key Points:

Price Structure: Prices are strongly correlated with futures prices of metals such as nickel and cobalt. High costs are primarily due to complex melting, processing, and heat treatment processes.

Clear Technical Agreement: Before business negotiations, a detailed technical agreement must be signed, locking in material standards, delivery status, dimensional tolerances, testing items, acceptance criteria, and document delivery lists.

Pay attention to delivery time and minimum order quantity: The production cycle for this type of special strip is long (usually 2-4 months or longer), and there is a minimum order quantity. Be sure to plan and specify it in the contract.

Manufacturing Process and Challenges

Nimonic 90 nickel alloy strip has moderate machinability among high-temperature alloys, but still requires careful handling. Whether purchasing raw materials, machining simple parts, or precision-machined parts, the following points should be noted by skilled machining personnel regarding secondary processing:

Cold Working: Can be cold rolled, stamped, etc., but work hardening is significant, potentially requiring intermediate annealing.

Machining: Conventional machining methods are possible, but due to its high strength, tool wear is rapid. High-performance carbide tools are recommended, and adequate cooling is essential.

Welding: Good weldability. Inert gas shielded welding (such as TIG or MIG) in the solution-treated state is recommended. Post-weld treatment generally requires solution treatment and aging to restore properties.

Heat Treatment (Performance Criterion):

Solution Treatment: Typically performed at around 1080°C to dissolve the strengthening phase.

Aging Treatment: Performed at approximately 700-750°C to promote uniform and dispersed precipitation of the γ' strengthening phase, a crucial step in achieving final high-temperature strength.

Key Points of Quality Inspection Process

The core of procuring Nimonic 90 alloy strip is obtaining a material with stable high strength and microstructure within the 800-900°C range. Before submitting an inquiry, consult with your team or, if unsure, our sales team to confirm that the final material used is Nimonic 90 alloy strip, not something else.

Action Recommendation: Before requesting a quote, please finalize the following with your design engineers, considering your specific operating conditions:

The precise operating temperature, stress environment, and expected lifespan of the component.

The most critical performance requirements for the material (creep strength, fatigue strength, or oxidation resistance).

The subsequent processing techniques for the strip (whether deep drawing, welding, etc.) are required.

If you can provide more specific application details (e.g., which specific engine component it will be used for), our professional sales and engineering team can help you analyze key performance indicators and potential processing risks.
