Product Inspection
1. Chemical Composition Inspection
Chemical composition analysis is performed to verify nickel, chromium, aluminum and other alloying elements. Since CrNi85Al may follow customer-specific requirements, composition verification is essential before shipment.
2. PMI Testing
PMI testing can be used to verify the alloy elements and prevent material mix-up. It is especially useful for high-nickel alloys and heat-resistant alloy materials.
3. Dimensional Inspection
Diameter, length, straightness, tolerance and surface condition are inspected before shipment to ensure the bar meets purchase order or drawing requirements.
4. Surface Inspection and Certificate Review
Surface quality, marking, packing label, heat number and material certificate are checked before delivery to support traceability and quality assurance.
