Hot Rolled Steel HA250 Laser Cutting Australia

What is Hot Rolled Steel HA250?

Hot Rolled Steel HA250 is a structural steel grade widely used in Australian engineering and fabrication. Manufactured to AS 1163 and AS/NZS 3678 standards, it offers a minimum yield strength of 250 MPa with reliable mechanical properties suited to structural and general fabrication applications.

The hot-rolling process produces a characteristic mill scale surface finish. This scale is removed during laser cutting at the cut edge, resulting in a clean, precise profile. HA250 is compatible with all standard welding processes and is commonly powder coated or painted after fabrication.

Why Choose HA250 for Laser Cutting?

• Structural-grade strength — 250 MPa yield, suitable for load-bearing applications
• Excellent weldability — compatible with MIG, TIG, and arc welding
• Cost-effective — economical choice for high-volume structural components
• Good machinability — easy to drill, tap, and finish after cutting
• Wide availability — standard stocked material across Australia

Available Thicknesses

Ferracut laser cuts Hot Rolled Steel HA250 up to 20mm. Common thicknesses: 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm.

Tolerances and Edge Quality

Laser cutting HA250 achieves tolerances of ±0.1mm on thicknesses up to 6mm and ±0.2mm on heavier plate. Hot-rolled material may have minor surface scale variation, but cut edge quality is consistent. Oxygen assist gas is used on thicker sections for efficient material removal.

Common Applications

• Structural frames and supports
• Mining equipment components and wear parts
• Agricultural machinery and implements
• Trailer and chassis components
• Industrial brackets and gussets
• Building and construction hardware

File Preparation Tips

• Supply files as DXF or DWG at 1:1 scale in millimetres
• All cut paths must be closed loops
• Minimum internal hole diameter equal to or greater than material thickness
• Remove annotations, hatching, and dimension layers before export
