Wear-resistant steels are used in applications where abrasion, wear and impact are the main causes of failure, not constant pressure or tension. So, such steels make the ideal choice for using in heavy-duty equipment and attachments in challenging or extreme environments.
Typical uses for SSAB's wear-resistant steels include:
ANSWER:
While AR refers to "abrasion resistance," the number in the grade, "400" or "500," refers to the Brinell Hardness. AR500, therefore, has a higher Brinell Hardness than AR400.
Unlike other steels, where the primary properties taken into consideration are tensile strength or toughness, abrasion resistant steels are graded according to their Brinnell Hardness. Hardness is one of the most important factors when it comes to abrasion resistance.
Because of its impact and wear durability, AR400 is typically used when high wear resistance is a requirement, for example in digger blades and buckets, heavy machinery, and mining machinery. The addition of chromium increases its corrosion resistance, wear resistance, hardenability, and abrasion resistance.
AR500 is a medium carbon, abrasion resistant steel that is alloyed with manganese. Designed for impact resistance and wear, it has outstanding fatigue and corrosion resistance. AR500 is delivered heat treated for both hardening and better welding. Because of its durability, you'll find AR500 frequently in truck trailers, concrete and aggregate industries, and mining equipment.
However, AR400 and AR500 aren't so different that they aren't interchangeable in many applications, like mining equipment, cement pouring and forming equipment, excavation equipment, and conveyor systems.
