Rod, pin CK45 fi 90

Rods made of high-quality carbon structural steel corresponding to the Japanese standard S45C, the American 1045, and the German C45. They are characterized by higher strength and resistance to deformation than ordinary steel A3. The rods are hardened at a temperature of 840°C and tempered at a temperature of 600°C, followed by chrome plating to improve wear and corrosion resistance, resulting in a hardness level of 52-58 HRC.
