HARDNESS

477 – 550 BHN

Minimum surface hardness of 477 BHN. Core hardness 450 min BHN.

IMPACT STRENGTH

CVNL average values of 20ft. lbs at -40 ° F.

CUTTING

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

MACHINING

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

FORMING

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.

WELDING

Low-hydrogen-producing electrodes must be used in welding. Where maximum strength of joining plates is not important, rod type AWS E7016, 15, or 18 should be used, or our Tensaweld Workmate for welding wire options. If the weld joint is to be subjected to wear, finish the structural joint slightly below the surface and cap with Tensaweld Ultra-100. When higher weld strengths are required, electrodes of the AWS E90, E100 or E120 low hydrogen series, or Tensaweld Nickel-90 should be used, depending on the strength levels required.
