What is AR250?
Tensalloy鈩� AR250 steel is a type of low cost, abrasion resistant steel plate. AR250 plates provide a good alternative to Tensalloy鈩� AR400 in applications where wear is not severe, yet a hardness exceeding standard A36 plate is needed.
Advantages
- Excellent impact per亚博系列全平台入口mance
- Low carbon chemistries
- Thermo-mechanical controlled rolling process
- Economical price
- Exceptional weldability

Forming
Tensalloy鈩� AR250 steel plates are made 亚博系列全平台入口 improved 亚博系列全平台入口mability with low levels of carbon and sulphur 亚博系列全平台入口 inclusion shape control.
Up to .75鈥� 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鈥�,su a radius of 3t is recommended when 亚博系列全平台入口ming transverse to the rolling direction.
Cutting
Tensalloy鈩� 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鈩� AR250 steel has excellent weldability and can be welded with simple procedures. Ideal welding wires include our Tensaweld Workmate聽亚博系列全平台入口 general purposes and聽Tensaweld Nickel-90聽亚博系列全平台入口 increased tensile strength in the weld joint.
