What is HRP&O Carbon Steel?

HRP&O steel is much smoother and easier to finish than the cheaper “mill finished hot-roll” that most steel centers sell. HRP&O is just hot-rolled steel that is subjected to an acid bath to remove scale mill. Then it has some dry oil applied to prevent rusting. Overall, it has a nicer finish.

What can you make with HRP&O Carbon Steel parts

With A36/A1018 HRP&O sheet metal, you can fabricate a wide array of products including structural beams, automotive components, machinery parts, and industrial equipment. Its superior formability and weldability make it ideal for creating frames, brackets, supports, and enclosures. Additionally, its robustness and durability allow for the manufacturing of load-bearing structures and components that require high strength and resilience, ensuring reliability and longevity in demanding applications.

A36/A1018 HRP&O for precision fabrication and forming

A36/A1018 HRP&O combines the strength of A36 with the tight thickness and surface control of A1018 giving you the best of both worlds. It’s strong, consistent, and ideal for parts requiring laser cutting, bending, and hardware installation without the rough mill scale of hot rolled steel.

5 key takeaways for A36/A1018 HRP&O

  • Balanced performance: Strength of A36 with improved surface and dimensional accuracy from A1018.
  • Laser cut precision: ±.005″ tolerance and clean edges.
  • Better surface finish: Smoother and more uniform than typical hot rolled steel.
  • Excellent weldability and formability: Works well for structural and mechanical parts.
  • Compatible with SendCutSend services: Bending, hardware insertion, powder coating, plating, tapping, and tumbling.

What is A36/A1018 HRP&O?

A36/A1018 is a blended specification combining two ASTM standards to create a versatile, high-strength mild steel with tighter dimensional control. This material is ideal when you want the reliable weldability and toughness of A36 but with the smoother finish and consistency of cold rolled or A1018 steel.

What are the mechanical and physical properties of A36/A1018 steel?

It shares much of A36’s strength but with improved consistency and surface condition. Typical properties:

  • Density: 0.283 lb/in³ (7.83 g/cm³)
  • Tensile strength: ~58–80 ksi
  • Yield strength: ~36–50 ksi
  • Elongation: ~20%

This combination makes A36/A1018 an ideal sheet material for precision fabrication, brackets, and welded assemblies.

How does A36/A1018 perform during laser cutting?

A36/A1018 laser cuts with excellent accuracy and smooth edges.

  • Tolerances: ±.005″ for all available thicknesses (.030″–.500″).
  • Edge quality: Smooth and uniform, with minimal oxide residue.
  • Cut behavior: Consistent due to uniform thickness and surface flatness.

See our Design Guidelines for cutting and feature size recommendations.

Can A36/A1018 be bent or formed?

Yes, SendCutSend offers bending services on HRP&O. This steel bends and forms cleanly without flaking or cracking.

  • Inside bend radius: 1–1.5x material thickness.
  • Consistent grain structure allows for reliable, repeatable bends.
  • Suitable for parts with multiple bends or dimples.

Refer to our Bending Guidelines for geometry tips.

Can A36/A1018 be welded, tapped, or finished?

A36/A1018 accepts all common fabrication processes.

  • Weldable using MIG, TIG, or stick processes.
  • Easy to tap or add hardware inserts.
  • Compatible with all SendCutSend finishing services including plating, powder coating, and tumbling.

Before adding secondary services to your HRP&O parts, reference our service and design guidelines.
