Overview

About this mild steel square bar

The Black Mild Steel Square Bar with a 16 mm dimension is a versatile and robust material suitable for a variety of applications. Its excellent weldability and machinability make it an ideal choice for construction, manufacturing, and engineering projects. However, due to its poor corrosion resistance, it requires appropriate protective measures when used in corrosive environments. 

  • Material: Mild Steel is a known for its versatility, offering a good balance of strength, ductility, and ease of fabrication.

  • Dimensions: Size Metric: 16 mm for height, thickness, and width, providing a sturdy and robust profile suitable for heavy-duty applications.

  • Formability: Rated as excellent, allowing the material to be easily shaped and formed into various configurations without cracking or breaking.

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

  • Machinability: Rated as excellent, meaning the material can be easily machined to precise dimensions and finishes, making it suitable for components requiring high precision.

  • Corrosion Resistance: Rated as poor, indicating the material is prone to rust and corrosion if not protected. It requires appropriate coatings or regular maintenance to prevent degradation in corrosive environments.

  • Finish: The natural mill finish of the steel as produced by the mill, without any additional surface treatment. It often requires further finishing processes depending on the application.

  • Weight: With a weight per metre of 2.01 kg, the square bar provides substantial mass suitable for structural and load-bearing applications.
