AR400 STEEL SPECIFICATIONS

HARDNESS

360 – 440 BHN

IMPACT STRENGTH

CVNL average values of 15ft. lbs at -40° F

CUTTING

AR400 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 is performed with conventional equipment and carbide tools.

FORMING

AR400 is specially made for improved formability with low levels of carbon and sulphur for inclusion shape control.

Up to .75″ can be cold bent to minimum inside bend radius of 3t (where t is the plate thickness) with the bend axis transverse to the rolling direction. A radius of 4t can be used when bending parallel to the roll direction.

For plate over .750″ a radius of 6t is recommended when forming transverse to the rolling direction.

WELDING

has excellent weldability and can be welded with simple procedures. Ideal welding wires include our Tensaweld Workmate for general purposes and Tensaweld Nickel-90 for increased tensile strength in the weld joint.
