What is CK45 chrome plated rod?
CK45 hard chrome plated rod is also called CK45 chrome rod or CK45 chrome bar for short sometimes, it is the hard chrome plated bar made of steel grade CK45. This product is widely used to manufacturer hydraulic piston rod, so it is also called CK45 hydraulic piston rod.
CK45 chrome plated bar is a medium tensile carbon steel CK45 supplied in the cold drawn or turned, precision ground, polished, chrome plated and final polished condition. The tensile strength of CK45 steel is 670 – 800 Mpa, and yield strength around 520 Mpa (75Ksi).
Steel grade CK45 is equivalent to SAE standard grade of SAE 1045, so this product is also known as 1045 chrome plated rod or 1045 Chrome Bar. Here below is the chemical composition and mechanical properties of CK45.
| Steel Grade | Chemical Composition % | ||||
| Carbon | Mn | Si | P | S | |
| CK45 (C45) | 0.42-0.50 | 0.50-0.80 | 0.40 Max | 0.035 Max | 0.035 Max |
| Steel Grade | Mechanical Properties | |||
| Yield Strength | Tensile Strength | Elongation | Hardness | |
| CK 45 | 75K psi / 517 Mpa | 85K psi / 585Mpa | 10% | Rc 60-72 |
