Hardox wear steel plate is a type of abrasion-resistant steel that is produced by SSAB. It is available in a range of grades, each with its own specific properties. The most common Hardox grades are:

• Hardox 400: This is the most versatile grade of Hardox, and it is suitable for a wide range of applications. It has a nominal hardness of 400 HBW.
• Hardox 450: This grade has a higher hardness than Hardox 400, and it is therefore more wear-resistant. It is also more difficult to process, but it offers a longer service life.
• Hardox 500: This grade has the highest hardness of all the Hardox grades, and it is therefore the most wear-resistant. It is also very strong and tough, making it suitable for demanding applications.
• Hardox 550: This grade has a nominal hardness of 550 HBW, which is even higher than Hardox 500. It is a good choice for applications where the wear conditions are extremely demanding, such as in the mining and recycling industries.
• Hardox Extreme: This is the newest grade of Hardox, and it has the highest hardness of any wear steel on the market. It is intended for applications where the highest possible wear resistance is required.

In addition to these standard grades, SSAB also offers a range of special grades of Hardox that are tailored to specific applications，such as Hardox HiTuf, Hardox Weldox, and Hardox 400 Tuf. These grades are designed for specific applications and offer additional properties, such as improved toughness or weldability. Hardox HiTuf is a grade of Hardox that has been heat-treated to improve its wear resistance. Hardox Tufftuf is a grade of Hardox that has been through a special manufacturing process that gives it even higher wear resistance than standard Hardox.

Hardox also offers a variety of other specifications for its wear steel plates. These specifications include:

• Thickness: Hardox wear steel plates are available in thicknesses from 2 to 130 mm (0.079 to 5.118”).
• Width: Hardox wear steel plates are available in widths up to 3350 mm (131.89”).
• Length: Hardox wear steel plates are available in lengths up to 14630 mm (575.98”).
• Surface finish: Hardox wear steel plates can be supplied with a variety of surface finishes, including smooth, blasted, and grooved.
• Weldability: Hardox wear steel plates are weldable, but special precautions must be taken to ensure that the welds do not compromise the wear resistance of the steel.

Hardox wear steel plate is used in a wide range of applications, including:

• Mining
• Construction
• Agriculture
• Marine
• Forestry
• Recycling

It is also used in a variety of other industries where abrasion resistance is important, such as the food processing industry, the chemical industry, and the waste management industry.

The main advantages of Hardox wear steel plate are its high wear resistance, its strength, and its toughness. It is also a relatively easy material to work with, and it can be welded and machined.

The main disadvantages of Hardox wear steel plate are its high cost and its weight. It is also a brittle material, so it is important to avoid impact loads.

Overall, Hardox wear steel plate is a versatile and high-performance material that is well-suited for a wide range of applications where abrasion resistance is important.
