Overview

About this mild steel square bar

This Black Mild Steel Square Bar measures 12mm x 12mm x 12mm and offers excellent weldability, formability, and machinability. However, it has poor corrosion resistance. The mill finish provides a standard surface appearance.

  • Material: Mild Steel is a versatile and commonly used form of steel with low carbon content, offering a good balance of strength and ductility.

  • Dimensions: 12mm, referring to the height, thickness, and width of the square bar, making it suitable for precision applications and small-scale constructions.

  • Formability: Rated as excellent, meaning the material can be easily bent, shaped, and formed without cracking, ideal for various fabrication processes.

  • Weldability: Rated as excellent, indicating that the material can be readily welded using standard welding techniques, ensuring strong and durable joints.

  • Machinability: Rated as excellent, signifying that the material can be easily machined to precise dimensions and finishes, making it suitable for manufacturing intricate components.

  • Corrosion Resistance: Rated as poor, suggesting that the material is prone to rust and corrosion if not adequately protected. This requires the application of protective coatings or regular maintenance in corrosive environments.

  • Finish: The standard finish resulting from the manufacturing process, typically rough and requiring further treatment or machining for a polished surface.

  • Weight: With a weight per metre of 1.13  kg, the square bar is lightweight and manageable, making it easy to handle in various applications.
