General Info About AR450 / AR450F

This is a high-carbon alloy steel that is perfect for rugged applications that require high wear resistance. It has more hardness than the AR400 steel plate with good formability, good weldability, good ductility, good strength, and good impact resistance.

More Details About AR450 / AR450F

  • Advantages/Disadvantages

    This grade is an high-endurance steel with long lasting results. It withstands wear and tear while retaining a world-class surface finish. One disadvantage of this grade is that machining is not recommended.

  • Industries

    This grade is often used in the mining, architectural, recycling, and construction industries.

  • Applications

    This grade is best for heavy wear applications. This includes construction equipment, dump body trucks, buckets, and components.

  • Machining

    This grade is not recommended for machining

  • Welding

    It has good weldability.

  • Heat Treatment

    It is heat treatable.

Frequently Asked Questions About AR450 / AR450F

  • What is this grade steel used for?

    It is used where high wear resistance is needed. This includes heavy machinery found in the recycling, mining, aggregate, and construction industries.

  • What makes AR450 steel so durable?

    The durability of this steel grade is directly linked to its tensile strength. High tensile strength indicates resistance to deformation. Likewise, it shows a surface hardness nearly four times that of other carbon steels.

  • What is the difference between AR400 and AR450 steel?

    Classifications for abrasion resistant steels correspond to their typical Brinell Hardness Number. Therefore, AR400 will have a lower hardness than AR450. However, AR400 or AR400F has better weldability than AR450 or AR450F. Another difference is that AR400 can be machined whereas AR450 is not recommended for machining.
