Haynes 263 Nickel Alloy Sheet
Haynes 263 Nickel Alloy Sheet Description
Haynes 263 (UNS N07263 / W.Nr. 2.4650) is an age-hardenable nickel-cobalt-chromium-molybdenum alloy sheet specifically designed to combine good age-hardened strength with excellent fabricability in the annealed condition. It is primarily intended to address the strain-age cracking issues commonly associated with γ′-strengthened alloys like Waspaloy and R-41, while maintaining ease of forming and welding.
Procurement Considerations
Confirm Standards and Product Form
Standard Specification: Clearly define the applicable standard for the material.
Form Distinction: Clearly specify whether the material is required as sheet or plate.
Clarify Delivery Condition
Default Condition: Typically delivered in the solution heat-treated condition to facilitate subsequent forming and welding by the customer.
Aged Condition: If specific strength levels are required for immediate use, confirm whether the supplier offers the material in an aged condition (a typical aging treatment is 800°C for 8 hours, followed by air cooling)
Supplier Qualification Verification
Melting Process: Require the supplier to specify the melting process (e.g., VIM+ESR/VAR) to ensure material purity.
Quality Documentation: Request the MTC (Material Test Certificate); if necessary, ask for third-party inspection reports or high-temperature creep-rupture performance data
