Black Steel vs. Mild Steel: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 22, 2024
Black steel is uncoated and stronger due to its composition, while mild steel is less carbon-rich and more malleable.

Key Differences

Black steel, known for its strength and durability, is often used in high-stress applications. Mild steel, with lower carbon content, is more ductile and weldable, making it suitable for various construction projects.
