What is AR250?
Tensalloy™ AR250 steel is a type of low cost, abrasion resistant steel plate. AR250 plates provide a good alternative to Tensalloy™ AR400 in applications where wear is not severe, yet a hardness exceeding standard A36 plate is needed.
Advantages
- Excellent impact performance
- Low carbon chemistries
- Thermo-mechanical controlled rolling process
- Economical price
- Exceptional weldability

Forming
Tensalloy™ AR250 steel plates are 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 1.75t (where t is the plate thickness) with the bend axis transverse to the rolling direction. A radius of 2.5t can be used when bending parallel to the roll direction.
For plate over .750″,su a radius of 3t is recommended when forming transverse to the rolling direction.
Cutting
Tensalloy™ AR250 steel can be cut 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.
Welding
Tensalloy™ AR250 steel 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.
