AR250 ABRASION RESISTANT STEEL PLATE

|
|
Econalloy AR250 is a low cost abrasion resistant steel plate that offers outstanding wear and impact resistance at an economical price. Econalloy AR250 offers superior weldability, formability, and toughness in combination with good weathering characteristics. In addition, it exhibits improved flatness and a clean surface.
This excellent combination of properties is possible because of the low carbon chemistries and the thermo-mechanical controlled rolling processes used in the manufacture of Econalloy. Econalloy plates provide a good alternative to AR400 in applications where wear is not severe yet a hardness exceeding standard A36 plates is needed.

Hardness 200 – 270 BHN Impact Strength Charpy Impact Properties (Longitudinal Specimen), Minimum 20 ft-lb @ -40 ºF (27 J @ -40 ºC) Cutting Econalloy 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. Forming Econalloy AR250 is 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" a radius of 3t is recommended when forming transverse to the rolling direction. Welding Econalloy has excellent weldability and can be welded with simple procedures and common consumables such as E7018.
