1. Visual Inspection: Check the surface for defects such as cracks, pores, and slag inclusions.
2. Dimensional Inspection: Measure key dimensions using calipers, height gauges, and other tools to ensure compliance with design requirements.
3. Non-Destructive Testing: Use magnetic particle testing or ultrasonic testing to detect internal defects.
4. Performance Testing: Conduct sample high-temperature tensile tests and oxidation resistance tests to verify material performance.
