Importance of Hydrogen Removal after Fastener Plating
Hydrogen removal after fastener plating is a critical post-treatment process, primarily due to the risk of hydrogen embrittlement—a phenomenon that can lead to catastrophic fastener failure, especially in high-strength materials. Here’s why it’s important and how it’s typically addressed:

How many ways to dehydrogenate fasteners?
Most common and effective method for high-strength fasteners.
Process: Heating fasteners at 190–230°C (375–450°F) for 4–24 hours (depends on material strength and plating type).
Key Considerations:

Would you like details on baking parameters for specific fastener grades?
To ensure effective hydrogen embrittlement relief (HER), the baking time and temperature must be optimized based on:
Fastener material strength (e.g., Grade 5 vs. Grade 8)
Plating type (e.g., zinc, cadmium, chrome)
Industry standards (e.g., ASTM, ISO, MIL-SPEC)

Why is annealing necessary for the continuous galvanising process?
Improved machinability: Annealing reduces the hardness of the metal, making it easier to perform machining operations such as bending and stretching, and less prone to breakage. The annealing process removes some of the internal stresses, making the metal smoother to machine and reducing the risk of cracking or fracture. In addition, annealed metal performs well when welded, with superior weld qua

Why plating should be equipped with ultrasonic cleaning
Ultrasonic wave through high-frequency vibration generated by the cavitation effect and mechanical vibration effect (such as eddy current, shear force), can quickly strip the parts surface oil, oxide layer, polishing paste and small particles of impurities.
