AR450 STEEL SPECIFICATIONS
400 –477 BHN
AR450 can be cut to your exact 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.
AR450 is made for improved formability control of inclusion shape.
For plate over .750″ a radius of 6t is recommended when forming transverse to the rolling direction.
AR450 has excellent weldability and can be welded with simple procedures. Ideal welding wires include our Workmate for general purposes and Nickel-90 for increased tensile strength in the weld joint.
