1. Chemical Composition of rolled steel rod
Standard "1045 Grade"
| Carbon | 0.43-0.50 |
Manganese | 0.60-0.90 |
Phosphorus (max) | 0.040 |
Sulfur (max) | 0.050 |
The mechanical property ranges for rolled steel rod are approximated to determine the expected performance of the material. These measurements can vary based on factors such as the composition of the steel and the manufacturing process used. It is important to note that the properties of rolled steel rod may fall within a range rather than being an exact value. Therefore, it is vital to consider the range of values instead of a single point estimate when working with this material.
"Grade 1045"
Tensile strength (psi) | 85,000 - 95,000 |
Yield strength (psi) | 45,000 - 55,000 |
Elongation in 2” (%) | 15 - 20 |
Reduction of area (%) | 30 - 40 |
Brinell Hardness (BHN) | 170 - 200 |
3. The characteristics of rolled steel rod
1045 is the designation for a round bar made of hot rolled mild steel. It exhibits excellent properties, making it a popular choice in various applications.
Machining, forging, heat treatment, and cold drawing are among the various processes that can be applied to medium carbon steel.
Lower carbon steels have lower strength compared to 1045 after heat treatment. While grade C1045 offers acceptable machinability and can be hammer forged, it has limitations when it comes to shaping and welding.
