AR400 Steel Laser & Waterjet Parts – Abrasion-Resistant Cutting & Bending

AR400 is a type of abrasion-resistant (AR) steel plate known for its excellent hardness and wear resistance. With a nominal hardness of 400 Brinell, AR400 is produced through quenching and tempering processes, where the steel is heated and rapidly cooled to create a tough, hardened structure. It is manufactured mainly by rolling and heat treating, and can be cut using plasma, laser, or waterjet cutting methods. AR400 is widely used in industries like mining, construction, and material handling for applications such as dump truck beds, hopper liners, chutes, crushers, and heavy machinery parts where abrasion and impact resistance are critical.

The advantages of AR400 steel include outstanding wear resistance, high impact toughness, and relatively good formability for such a hard material. It offers a longer service life in harsh environments, reducing downtime and maintenance costs. However, AR400 does come with some disadvantages: its high hardness makes it more difficult to machine and weld compared to softer steels, often requiring specialized tools and techniques. It can also be less flexible and more prone to cracking under extreme cold temperatures if not properly managed. Despite these limitations, AR400 remains a top choice when durability and abrasion resistance are key priorities.
