Alloy 282 (UNS N07208) is a premium wrought gamma-prime strengthened nickel-based superalloy, specifically engineered for extreme high-temperature structural service conditions. Governed by the AMS 5951 industry specification, this standard covers corrosion and heat-resistant nickel alloy sheet, strip, and plate products with controlled thickness ranging from 0.020 inch to 1.0 inch (0.508 mm to 25.4 mm).

As a professional China high-performance nickel alloy supplier,ZYTC Alloy provides fully AMS 5951 compliant Alloy 282 sheet and strip products with strict dimensional tolerance control and stable metallurgical performance. Different from traditional nickel superalloys, Alloy 282 achieves an optimal balance of high-temperature creep strength, thermal stability, weldability and fabricability, filling the performance gap of conventional commercial superalloys for aerospace and industrial gas turbine applications.

Professional Heat Treatment Process

ZYTC Alloy supplies Alloy 282 sheet in a standard solution-annealed state, which features excellent ductility and machinability for secondary forming and fabrication. The conventional solution-annealing temperature is controlled between 2050°F and 2100°F (1121°C to 1149°C). After component molding, targeted heat treatment can precipitate and grow Ni3Al gamma prime phase, significantly improving the material’s structural strength. We provide three mature heat treatment solutions to meet diverse application standards:

1. Standard Two-Step Heat Treatment

1850°F (1010°C) / 2 hours / air cool (AC) + 1450°F (788°C) / 8 hours / AC This is the original standard heat treatment process for Alloy 282, applicable to most conventional high-temperature structural parts.

2. Patented Optimized Two-Step Heat Treatment

1650°F (899°C) / 4 hours / AC + 1450°F (788°C) / 8 hours / AC Developed based on professional patented technology, this process effectively improves the material containment factor and further enhances structural stability under extreme working conditions.

3. ASME Standard Single-Step Heat Treatment

1475°F (802°C) / 8 hours / AC Compliant with ASME pressure vessel code (Code Case 3024), specially customized for pressure vessel and pressure-bearing high-temperature equipment manufacturing scenarios.
