General Info About AR200

This grade is a high value abrasion resistant steel. Abrasion resistance extends the life of the steel plate as it shows less wear in response to friction and rubbing. It is a high carbon steel with good hardness and moderate machinability.

More Details About AR200

  • Advantages/Disadvantages

    This grade shows high abrasion resistance and good hardness. One disadvantage of high carbon steel is that it has lower ductility.

  • Industries

    It is seen in the truck, bus, manufacturing, and construction industries.

  • Applications

    This grade is seen in moderate wear applications such as hoppers, truck liners, material chutes, and surfaces. It is not intended for structural use.

  • Machining

    It has fair to good machinability.

  • Welding

    It has good weldability.

  • Heat Treatment

    It is heat treatable.

Frequently Asked Questions About AR200

  • What is abrasion resistant steel?

    Abrasion resistant steel is a high-carbon alloy steel. It is formable and weather resistant due to alloy composition. It is also harder due to higher carbon content. The surface resists being worn down by friction and rubbing.

  • What are the AR steel grades?

    The AR steel grades include: AR200, AR235, AR Medium, AR400/400F, AR450/450F, AR500/500F, and AR600.

  • What is the difference between AR200 and AR400?

    AR200 and AR400 are both Abrasion Resistant steel plates. However, they differ in terms of hardness. AR400 is harder than AR200.

  • What is the difference between AR200, AR235, and AR Medium

    Abrasion resistant steel plates are distinguished by their hardness, not their chemical properties. AR Medium plates are the abrasion resistant plates which fall under the class of moderate wear AR plates, which includes AR200 and AR235. The numbers 200 and 235 refer to the expected Brinell hardness for each AR plate. Typically, moderate wear AR plates are not meant for structural application, but will last nearly 4x longer than other high-strength steels.
