1045 medium strength carbon steel bar
The 1045 tensile carbon steel bar is a commonly used steel bar with excellent strength and durability. With a tensile strength of between 570 and 700 mpa, the rod is suitable for a wide range of industrial applications, including construction, engineering and manufacturing. The 1045 medium drawn carbon steel bar offers a good elongation of 50mm, ranging from 14% to 30%. This means it can bend without breaking, making it a versatile material that can be used in many different types of structures and devices.
