Hardox 400 vs ar400

Hardox 400 and AR400 are both abrasion-resistant steel plates with similar properties. Here's a comparison between the two:

Manufacturer: Hardox 400 is a brand of abrasion-resistant steel manufactured by SSAB, a Swedish steel company known for its high-quality specialty steels. AR400, on the other hand, is a generic term used to refer to abrasion-resistant steel plates produced by various manufacturers.

Chemical Composition: Hardox 400 has a consistent chemical composition specified by SSAB, ensuring uniform performance. AR400 may have variations in chemical composition depending on the manufacturer, although they generally meet the minimum requirements for abrasion resistance.

Hardness: Both Hardox 400 and AR400 have a hardness level of approximately 400 HBW (Brinell Hardness). This indicates their excellent resistance to abrasive wear. The actual hardness may vary slightly depending on the specific heat treatment and manufacturing processes.

Tensile Strength: The minimum specified tensile strength for Hardox 400 is typically around 1250 MPa. Similarly, AR400 is expected to have a minimum tensile strength of approximately 1250 MPa.

Impact Toughness: Hardox 400 is known for its superior impact toughness, allowing it to absorb energy without fracturing under impact loads. The impact toughness of AR400 may vary among different manufacturers but generally provides good resistance to impact and fatigue.

Availability: Hardox 400 is a well-established brand recognized globally and readily available from authorized distributors worldwide. AR400, being a generic term, can be found from various suppliers, but availability may depend on the region and specific manufacturers.

While Hardox 400 and AR400 offer excellent abrasion resistance, there may be slight differences in terms of chemical composition, manufacturing processes, and overall consistency. When choosing between the two, factors such as brand reputation, availability, and specific project requirements should be considered. Consulting with steel specialists or suppliers can provide further guidance on selecting the most suitable option for your application.
