  • What is the blackening process of fasteners?

    What is the blackening process of fasteners?

    Because the blackening process does not cause hydrogen embrittlement to high-strength threaded fasteners, it is often used as a surface anti-corrosion treatment for high-strength threaded fasteners. The traditional blackening process is the alkaline blackening process. Because it requires a large ar... read more
