AR400 / AR450 / AR500 Abrasion Resistant Plate
Wear-resistant steel plate (AR steel plate) is a high-carbon alloy steel designed for extreme wear resistance in heavy-duty applications such as mining, construction, and material handling. After quenching and tempering, it typically has a high Brinell hardness (300-600+ BHN) and can withstand continuous friction, scratching, and impact.

Properties of AR400 and AR500 steel plates
AR400 is "thru-hardened", abrasion resistant, alloy wear plate. Hardness range is 360/440 BHN with a nominal hardness of 400 BHN. Service Temperature is 400°F. This plate product is intended for use in applications where a good balance of formability, weldability, toughness and abrasion resistance are required. Abrasion resistant steels are typically sold to hardness range and not a fixed chemistry. Slight variations in chemistry are present depending upon the producing mill. Applications may include use in mining, quarries, bulk material handling, steel mills, and pulp & paper industries. Wear plate products are designed for liner applications; they are not intended for use as self-supporting structures or lifting devices.

FAQ:
1.What is the difference between AR400 and AR500 plates?
The main difference between AR 400 and AR 500 steel plates is hardness. AR 500 is harder (at 500 Brinell) and has better abrasion resistance, while AR 400 (400 Brinell) is easier to machine and weld.
2.What is the difference between AR400 and AR450 steel?
AR450 steel has more surface hardness than AR400, good ductility and formability, as well as being impact resistant, as previously mentioned. It has a tensile strength of 214 KSI, yield strength of 181 KSI, and hardness of 429-495 Brinell.
3.Is AR400 abrasion resistant?
AR400 steel is an abrasion-resistant steel known for its exceptional hardness and durability. The "400" indicates its Brinell hardness rating, which typically ranges from 180 to 625 for AR steels.
4.What is the difference between Hardox 450 and AR 450?
Hardox 450 has a yield strength of around 175,000 lbs minimum yield. That is 75% stronger than 100K steel, and 250% stronger than 50K steel. The strength of AR450 steel can improve weight savings over 50K much like 100K material because a thinner material can be used without sacrificing strength.
5.How to tell if steel is AR400?
The Brinell Scale characterizes the hardness of steel through the scale of penetration of an indenter loaded on a material test piece. AR400 steel falls between 360 BHN and 440 BHN, whereas AR500 steel falls between 477 BHN and 550 BHN on the Brinell Scale.
