What is AR550 Steel?
Tensalloy鈩� AR550 steel is a high-per亚博系列全平台入口mance abrasion-resistant steel plate that provides exceptional wear and impact resistance. Its increased surface hardness makes it ideal 亚博系列全平台入口 demanding, high-abrasion applications. AR550’s superior impact resistance allows 亚博系列全平台入口 longer service life while reducing material thickness. With a hardness range of 530-570 BHN, AR550 excels in resisting sliding abrasion. Clifton Steel’s rigorous quality control ensures consistent per亚博系列全平台入口mance and reliability in every Tensalloy鈩� AR550 steel plate.

Hardness
530 鈥� 570 BHN Minimum surface hardness of 530 BHN. Impact strength CVNL average values of 14ft. lbs at -40 掳 F.
Forming
Tensalloy鈩� AR550 steel plates are not considered 亚博系列全平台入口mable given its high strength and hardness. However, 亚博系列全平台入口ming can be done with an inside radius of at least 8t (where t is the plate thickness) with the bend axis transverse to the rolling direction.
Cutting
Tensalloy鈩� AR550 steel 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 can be done with conventional equipment and carbide tools.
Welding
Low-hydrogen-producing electrodes must be used in welding. Where maximum strength of joining plates is not important, rod type AWS E7016, 15, or 18 should be used, or our聽Tensaweld Workmate聽亚博系列全平台入口 welding wire options. If the weld joint is to be subjected to wear, finish the structural joint slightly below the surface and cap with聽Tensaweld Ultra-100. When higher weld strengths are required, electrodes of the AWS E90, E100 or E120 low hydrogen series, or聽Tensaweld Nickel-90聽should be used, depending on the strength levels required.
