What is 1045 chrome plated bar?
1045 hard chrome plated bar is also called 1045 chrome bar or 1045 chrome rod for short sometimes, it is the hard chrome plated shafts made of steel grade SAE 1045.
1045 chrome plated rod is a medium tensile carbon steel SAE 1045 supplied in the cold drawn or turned, precision ground, polished, chrome plated and final polished condition. The tensile strength of SAE 1045 steel is 670 – 800 Mpa, and yield strength around 520 Mpa (75Ksi).
Steel grade SAE 1045 is equivalent to German standard grade of CK45 or C45, so this product is also known as CK45 chrome plated rod or CK45 Chrome Bar. Here below is the chemical composition and mechanical properties of SAE 1045 and CK45.
| Steel Grade | Chemical Composition % | ||||
| Carbon | Mn | Si | P | S | |
| SAE 1045 | 0.43-0.50 | 0.60-0.90 | – | 0.040 Max | 0.050 Max |
| 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 | |
| SAE 1045 | 75000 psi / 517 Mpa | 85000 psi / 585Mpa | 10% | Rc 60-72 |
| CK 45 | 75000 psi / 517 Mpa | 85000 psi / 585Mpa | 10% | Rc 60-72 |
