What is Hot Rolled Carbon Steel?

Our hot rolled carbon steel is commercial mild steel, found in most industries as it offers good weldability and machinability. It’s sturdy and easy to work with. It has a scaled surface finish from the cooling process and as a result, it is free of internal stresses sometimes associated with further processing. Hot rolled steel can be used in bending but is more prone to cracking.

What can you make with Hot Rolled Carbon Steel parts?

With A36 hot rolled sheet metal, you can manufacture a wide range of products including structural beams, support frames, and brackets. Its excellent weldability and machinability make it ideal for creating industrial machinery parts, construction components, and heavy equipment. Additionally, A36 steel is commonly used in the fabrication of enclosures, base plates, and various metal structures that require durability and strength.

A36 hot rolled mild steel sheet for structural and fabrication projects

A36 hot rolled mild steel is one of the most common and reliable steels used in fabrication. Known for its toughness, weldability, and cost-effectiveness, A36 performs well in brackets, frames, and heavy-duty structural parts. Its characteristic scale finish and slightly looser tolerances make it ideal where aesthetics take a back seat to strength and durability. Below, we answer the most common questions about A36 and how to design your parts for precision laser cutting.

Key takeaways for A36 hot rolled mild steel

  • Tough and dependable: A36 is strong, weldable, and affordable — perfect for structural or mechanical parts.
  • Laser cut precision: SendCutSend laser cuts A36 to ±.005″ across all available thicknesses.
  • Excellent weldability: Works well with MIG, TIG, and stick welding.
  • Hot rolled finish: Characteristic dark mill scale surface with slightly looser thickness tolerance than cold rolled steel.
  • Available services: Hardware insertion, plating, powder coating, tapping, and tumbling.

What is A36 hot rolled mild steel?

A36 is a low-carbon, hot rolled mild steel that offers a balance of strength, machinability, and affordability. It’s produced by rolling the steel at high temperatures, which improves ductility and makes large shapes easier to form. The result is a strong, versatile steel with a scale-covered finish. It’s ideal for welded or structural components. SendCutSend stocks A36 as one of three types of Mild Steel

What are the mechanical and physical properties of A36 steel?

A36 provides solid strength with good ductility and weldability. Typical properties:

  • Density: 0.283 lb/in³ (7.83 g/cm³)
  • Tensile strength: ~58–80 ksi
  • Yield strength: ~36 ksi
  • Elongation: ~20%

Because A36 is hot rolled, it’s not as dimensionally precise as cold rolled 1008, but it’s easier to produce and more cost-efficient for thicker, load-bearing parts.

How does A36 perform during laser cutting?

A36 laser cuts cleanly with SendCutSend’s high-powered systems, achieving tight tolerances and smooth edges.

  • Tolerances: ±.005″ across all available thicknesses (.030″–.500″).
  • Edge quality: Clean, slightly darker edge color due to carbon content and mill scale.
  • Heat-affected zone: Minimal, no warping in typical sheet thicknesses.

To optimize results, follow our Design Guidelines for minimum hole and feature sizes.

Can A36 be welded or joined?

A36 is one of the easiest steels to weld.

  • Suitable for MIG, TIG, or stick welding.
  • No preheat required for most sheet thicknesses.
  • Compatible with common filler metals like ER70S-6.

It’s widely used for welded frames, brackets, and structural weldments.

What finishing options work best for A36?

Because A36 has a mill scale surface, finishing options help protect and enhance appearance. SendCutSend offers:
