Rod blackening treatment process

Clubs such as forged clubs are soft, so the ground is stable, the ball does not roll, and it is the best choice for professional players or low handicap players. From the perspective of design and manufacturing, the material of forged irons is usually 1020 low-carbon steel, 1025 low-carbon steel, and the impact surface hardness of forged irons is generally HRB 65-85. These two materials are currently the most mature processes.

Nitriding and blackening treatment process of forged club

1020 or 1025 steel will rust quickly at room temperature, so the forged ball head has to be electroplated, or the surface is nitrided and blackened to protect and extend the life of the club. The concept of rapid rust here is that the club will start to have rust spots after 1-2 months of use, and the surface will be completely rusted after 5 months. After the surface is electroplated or nitrided and blackened, generally speaking, non-professional players do not need to play rust every day within 2.5-3 years.

1025 series low carbon steel composition and performance see parameters. The surface nitriding blackening treatment process is QPQ treatment, which is called QPQ salt bath composite treatment technology in China. The effect of QPQ technology on the corrosion resistance of low carbon steel is studied in "The Effect of QPQ Technology's Nitriding Process on the Corrosion Resistance of Parts" ~ 3h salt bath nitriding + 400 ℃ × 30min oxidation + polishing + secondary oxidation + water washing to obtain the best performance of the workpiece.
