Fabrication and Processing
Cutting:
Hardox 600 can be cut using oxy-fuel, plasma, or laser cutting methods. Preheating may be required for thicker plates to avoid cracking.
Welding:
Although Hardox 600 has a high hardness, it is weldable using conventional welding techniques. Low-hydrogen electrodes and controlled heat input are recommended to ensure weld quality.
Bending and Forming:
Hardox 600 can be cold-formed with proper tooling and techniques. Preheating is advised for more complex bends or thicker plates.
Machining:
Due to its hardness, machining Hardox 600 requires specialized tools and equipment. Carbide-tipped tools and low cutting speeds are recommended.
