3.1.2. HARDOX 500, 600

Table 4 and Table 5 summarize the material characteristics of HARDOX steels [8,9]. These are high-strength (up to 1200 MPa), quenched, and slightly tempered abrasion-resistant steels with high hardness (up to 600 HB). HARDOX steels combine the characteristics of structural steels and abrasion-resistant steels. They have high resistance, toughness, and hardness in the entire material width, i.e., not only on the surface. These properties provide a long lifetime in the most adverse conditions. The steels are well workable by cutting and bending, and well weldable.

Metal analysis of the SSAB HARDOX and ARMOX steels used. The content of the elements is provided in wt.% (SSAB datasheets) [8,9,10].

Basic mechanical properties of HARDOX 500 steel (SSAB datasheets) [8,9,10].

The steels are used mainly in applications with requirements of a very high lifespan and resistance to abrasive conditions. HARDOX steel plates are used in the mining industry: transport and processing of mineral raw materials.
