Mild steel round bars and alloy steel bar stock play pivotal roles in various industries, offering distinct properties to meet diverse application requirements. Mild steel, with its low carbon content, boasts ductility and cost-effectiveness, making it a popular choice. On the other hand, alloy steel bar stock incorporates alloying elements to enhance properties like strength, hard
ness, and corrosion resistance.
This blog delves into the grades, properties, and applications of mild steel round bars and alloy steel bar stock.
Mild Steel Round Bar Grades
Ductility Meets Versatility:
Mild steel round bars, characterized by a low carbon content (typically less than 0.25%), exhibit unique properties that contribute to their widespread use. Some common grades include:
- 1018: A general-purpose grade suitable for diverse applications.
- 1020: Similar to 1018 but with slightly higher carbon content, offering increased strength.
- 1045: With higher carbon content, it provides enhanced strength, hardness, and wear resistance.
- 1213: A free-machining grade designed for easy machining but less weldable.
- 12L14: A lead-bearing grade known for its machinability but limited weldability.
