Round Pneumatic Hard Chrome Plated Rod 9 Chrome Welding Rod
There are many other names for the optical shaft: chrome-plated rod, piston rod, electroplated rod, etc. There are many materials that can be made, such as No. 45 steel, bearing steel, 40Cr, A3 steel, etc. Different types of steel have different properties. The most common one is No. 45 steel, which belongs to high-carbon steel. The performance is improved through chrome plating, quenching, and high-frequency treatment. It can reach a maximum of 50-60 degrees, and it is not easy to process after hardening. There are also ordinary chrome-plated rods, that is, no quenching and high-frequency hardening. The hardness of bearing steel can reach 62 degrees, which is not easy to process, but it is more wear-resistant and has a long service life. 40Cr has good toughness after quenching and tempering. It belongs to medium carbon steel. A3 is not recommended, and its performance is relatively poor.
