Gas cutting of HARDOX plate is easy. As in all thermal cutting, a heat-affected zone occurs at the cut surface. Thick HARDOX 400/450/500 should be preheated before gas cutting.

For producing smaller parts or to minimize hardness reduction in the zone adjacent to the cut surface, abrasive water-jet cutting or laser cutting may be good alternatives to gas cutting.

In abrasive water-jet cutting, which is a cold- working process, the material will lose none of its hardness. In laser cutting, the heat-affected zone is very small.

Purity, flatness and consistent quality make HARDOX plate well suited for press and roll bending.

The table below shows examples of recommended minimum values for free bending of plate of different thicknesses and with different die openings.

The lower table shows examples of the bending forces needed for two different grades of plate. If the machine is capable of bending a given length of 1/4" in thick A-36, it will also be able to bend the same length of 3/16 in. thick HARDOX 400.

Bending & Shearing

HARDOX 400, HARDOX 450 and HARDOX 500 can be machined in all machine tools, using tools with indexable inserts and in a stable, vibration- free set-up.

HARDOX plate can also be machined in a stable radial drilling machine. Rigid HSS-Co drills must be used for drilling. Using appropriate tools, HARDOX plate can also be spot-faced and counterbored.

Machining of HARDOX plate may produce long chips, particularly in turning. This is due to the high purity of the plate.
