 Usage and Applications of Carbon Steel Round Bar

Carbon steel round bar is the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications, more so than iron. It is often used when large quantities of steel are needed, for example as structural steel. The density of this product is approximately 7.85g/cm³ and the young's modulus, like all steels.

Production Flow of Carbon Steel Round Bar

1. The common processes are preheated forging quenching, dual refinement solution process, cooling quenching and isothermal quenching. We use heat treatment for dual refinement solution process. The main measures process is high temperature solution and refinement cycle. High temperature solution can improve the carbide morphology and particle size. The aim is to make the loop refinement ultrafine austenite grains.

2. EAF+LF+VD+ Forged+ Heat Treatment
