Hardox is the trading name of a metal known as SSAB – an extremely tough and abrasion-resistant form of steel. It comes in a variety of thicknesses, depending on the application, but it is generally used in ‘heavy duty’ applications involving large machinery and wear plates.
Hardox is one of the hardest forms of steel available. As well as being highly wear-resistant, it is weldable, bendable and ideal for load bearing. It is during the production process that this steel acquires its unique strength. The precise addition of alloy elements and fast quenching processes create a robust, low maintenance and long lasting product that can withstand higher payloads than other types of steel.
Hardox is produced in the USA and Sweden though each country uses different steel manufacturing processes In the US, scrap is recycled in electric arc furnaces before being cast and cooled in continuous casting machines to form heavy plate steel, while in Sweden, iron ore pellets are melted in blast furnaces with a small amount of scrap added and the molten metal in made into crude steel in LD converters. This method is used to form both sheet metal and heavy plate.
Hardox is ideal for industries involving heavy duty equipment and infrastructure, such as cranes, dump trucks, earthmovers, or other vehicles that deal with the storage or movement of large payloads.
- Energy production
- Earth moving
- Heavy duty construction and demolition
- Freight containers
Hardox has a lifespan that is up to ten times greater than other types of steel.
