Description
What is AR200?
AR200 is a carbon-manganese steel alloy known for its moderate abrasion resistance and impact toughness. It is commonly used in applications requiring wear resistance, such as construction, mining, and material handling industries. With a balanced combination of strength, durability, and machinability, AR200 steel is a cost-effective choice for applications requiring increased longevity over mild steel.
