Mild Steel 250HR Laser Cutting Australia

What is Mild Steel 250HR?

Mild Steel 250HR is a hot-rolled structural steel manufactured to AS/NZS 3678 Grade 250. It is the most widely used and widely stocked steel grade in Australia, making it the default choice for general fabrication, structural work, and engineering components where maximum strength is not the primary requirement.

Its consistent composition and predictable cutting behaviour make it ideal for laser cutting — edges are clean, tolerances are tight, and the material responds reliably across the full thickness range up to 20mm.

Why Choose 250HR for Laser Cutting?

• Most cost-effective steel option — lowest material cost for structural-grade steel
• Excellent weldability — suitable for all standard welding processes
• Wide stock availability — short lead times, standard sheet sizes
• Consistent laser cutting performance — predictable results across thicknesses
• Highly machinable — easy to drill, tap, and post-process

Available Thicknesses

Ferracut laser cuts Mild Steel 250HR up to 20mm. Commonly stocked thicknesses: 1mm, 1.6mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 20mm.

Tolerances and Edge Quality

Standard tolerances of ±0.1mm on thicknesses up to 6mm, and ±0.2mm on thicker sections. Oxygen assist gas is used on thicker plate for optimal cut speed and edge quality. Edges are typically clean with minimal dross on standard thicknesses.

Common Applications

• General fabrication brackets and frames
• Enclosures, guards, and panels
• Structural components and gussets
• Agricultural equipment and implements
• Workshop tooling and fixtures
• Prototype parts and one-off components
• Signage backing and mounting hardware

File Preparation Tips for 250HR

• Export as DXF R14 or 2000 format from your CAD tool
• Use millimetres at 1:1 scale
• Ensure all paths are closed loops
• Minimum hole diameter equal to material thickness
• Run OVERKILL (AutoCAD) or equivalent to remove duplicate lines
