AR360 Steel – Composition, Properties, and Uses

AR360 Steel

Steel has become integral to modern industrialization, where its durability, strength, and various properties are used daily. The steel industry has evolved to produce different types of steel with unique compositions and properties, including Ar360 steel. Ar360 steel is an abrasion-resistant steel designed for applications requiring wear, impact, and corrosion resistance. This blog post aims to provide valuable insights into Ar360 steel composition, mechanical and physical properties, uses, corrosion resistance, heat treatment, machining, and welding.

AR360 Steel Composition

Ar360 steel plate is a low alloy steel with a composition that includes carbon, manganese, silicon, phosphorus, and sulfur. It also has chromium and nickel, significantly enhancing its strength, hardness, and wear resistance. The typical composition of Ar360 steel is 0.33% carbon, 1.5% manganese, 0.5% silicon, 0.025% sulphur, and 0.025% phosphorus. Besides, Ar360 steel has a higher nickel and chromium content than ordinary low-carbon steel.

AR360 Steel Mechanical Properties

Ar360 steel plate has high tensile strength, translating to its ability to resist deformation under load. It has a minimum yield strength of 360 MPa and a minimum tensile strength of 1100 MPa. Ar360 steel has excellent hardness at a rating of 360 HBW, making it useful when wear resistance is paramount. The steel has good impact resistance, low carbon content, and high weldability, making it suitable for various applications.

Ar360 Steel Physical Properties

The most outstanding physical property of Ar360 steel plate is its high abrasion resistance. Its high wear resistance makes it ideal for applications continuously exposing the material to wear and tear. Ar360 steel has a density of approximately 7.8g/cm³, which makes it relatively lightweight and highly manageable. Furthermore, steel has good machinability and can easily be cut, drilled, or shaped into various forms.

Ar360 Steel Uses

Ar360 steel plate has gained popularity in multiple industries due to its exceptional properties. It is commonly used in heavy-duty mining, construction, and agriculture equipment, where it is exposed to harsh environments and abrasive materials. Steel is also used in manufacturing machinery parts, such as conveyor belts, buckets, and bulldozer blades, where wear resistance is crucial. Ar360 steel is a suitable material for fabricating pipes, shafts, and bearings, and it is increasingly becoming the preferred steel for armour plating.

Ar360 Steel Corrosion Resistance and Heat Treatment

Ar360 steel plate has good corrosion resistance but requires regular maintenance to prevent rust and deterioration. The steel can be heat-treated to improve its wear resistance and increase its hardness.

AR360 Steel Machining

It can also be machined using conventional techniques, although the high hardness may require specialized equipment.

AR360 Steel Welding

Welding Ar360 steel requires careful consideration due to its high strength and hardness, and preheating and stress-relieving treatments may be necessary to prevent cracking and distortion.


Ar360 steel plate is uniquely well suited for heavy-duty applications and abrasive environments, thanks to its exceptional properties. Its composition, mechanical and physical properties, corrosion resistance, heat treatment, machining, and welding capabilities make it valuable in various industries. Therefore, it is no surprise that Ar360 steel has become increasingly popular, and it is worth considering if you require a durable and robust steel for your next project.
