What is the difference between AR400 steel and AR500 steel?

Abrasion Resistant (AR) steel contains carbon and alloys that make it harder than other types of steel. They are also less formable and not as weather resistant. However, their hardness contribute to AR steel being the preferred product in industrial manufacturing, mining, and construction, where abrasion and wear-and-tear are common factors.

WHAT IS AR400 STEEL?

AR400 steel plate is abrasion resistant steel that has a hardness between 360 BHN and 440 BHN. AR400 steel has a large range of general applications. It performs particularly well in conditions where impact resistance has a higher importance than abrasion resistance.

WHAT IS AR500 STEEL?

AR500 steel plate is chemically similar to AR400 steel plate, except the hardness range is higher and it has more carbon and manganese than AR400. These elemental differences help the steel achieve a higher surface hardness. To be classified as AR500, the hardness needs to clock in between 477 BHN and 550 BHN.

AR 400 and AR 500 steel plates are two of the most popular abrasion resistant steel plates in the world. 

While AR400 is known for its workability and AR500 is known for its tensile strength, each metal contains a few other hidden advantages which can directly benefit your project in any application
