Chrome plated rod is a very important material as cylinder rod for hydraulic cylinders and pneumatic cylinders. Usually we use steel round bar to produce hard chrome rod, materials like Ck45 1045 4140 42CrMo4 SS304/316 to keep the cylinder rod good working performance.
The heat treatment process is also very important to chrome cylinder rod. Normally the chrome plated bars are supplied with a certain heat treatment process. The heat treatment will provide the chrome plated rod with higher strength, high hardness and lower residual Stress. There are 3 main heat treatment process in Wuxi YUTONG for chrome plated steel bar as below.
- Quenching and tempering heat treatment: Q&T treatment is the most popular heat treatment for hard chrome plated rods, most of the materials of chromed rods such as CK45, SAE1045, 4140, 42Crmo4 can be Q&T heat treated.
- Induction hardened heat treatment
Induction hardened heat treatment usually is applied to get higher hardnen for the piston rods, chrome plated bar with this kind of heat treatment is known as induction hardened chrome rod. - Q&T treatment and then induction hardened
The heat treatment is applied before chrome plating, and some customers maybe not require the steel rods heat treated for some low requirement applications, in this case they can save some more cost.
