What is AR400 Steel?
The Tensalloy™ AR400 wear-resistant steel plate is a steel that provides greater impact strength than our other common heat treated alloys. As a result, customers can expect longer-lasting wear parts in some of the toughest applications. AR400 steel has a variety of benefits that makes it an ideal substitute for almost any application where excessive wear is a problem and ease of fabrication is needed.
AR400- better for impact applications, AR500- better for sliding applications. Read more about AR400 vs AR500 here.

Hardness
360 – 440 BHN
Impact strength
CVNL average values of 15ft. lbs at -40° F
Forming
Tensalloy™ 400 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.
Cutting
Tensalloy™ 400 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.
Welding
Tensalloy™ 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.
