Hardcore AR500 steel can be cut to your specifications with plasma, oxy-Acetylene, laser, and water jet, as well as with abrasive cut off saws.

Drilling, countersinking, counterboring, tapping, milling, and general machining can be done with conventional equipment and carbide tools.

HardCore AR500 steel plates are not formable given its high strength and hardness. However, forming can be done with an inside radius of at least 10t (where t is the plate thickness) with the bend axis transverse to the rolling direction.

Low-hydrogen-producing electrodes must be used in welding. Where the maximum strength of joining plates is not important, rod type AWS E7016, 15, or 18 should be used. If possible, 7018 and 8018 electrodes should be used with the 500 BHN steel. If the weld is to be subjected to wear, it may be capped with a hard facing electrode having a low hydrogen type coating. When higher weld strengths are required. electrodes of the AWS E90, E100, or E120 low hydrogen series should be used. Depending on the strength levels required.
