Hardox 500 weldability

    
    Based on the results of testing, HARDOX 500 is generally known as an exemplary weldable wear plate. Its high hardness, low alloys, and unique microstructure make it superior to other wear plates in terms of weldability and toughness.
    
    HARDOX 500 is an abrasion-resistant steel plate produced by Swedish steel manufacturer SSAB. The plate is intended for applications that require both high wear resistance and weldability. For example, the plate is used for the protection of heavy-duty equipment used in the mining, quarrying, and construction industries.
    
    HARDOX 500 is made with low-alloyed carbon steel containing elevated levels of chromium, nickel, and manganese. The chemistry and microstructure of the steel makes it highly resistant to abrasion and impact. In addition, the steel is strengthened via quenching, which helps to maintain consistent microstructure and excellent hardness.
    
    HARDOX 500, due to its high hardness, low alloying elements, and quenched microstructure, has excellent weldability characteristics. The steel can be welded in various methods and the weldability is not affected by the heat input used. The HARDOX 500 must be welded in a preheated condition for best results. The steel can be welded using manual metal arc welding and submerged arc welding, along with other techniques.
    
    HARDOX 500 also offers good toughness due to its unique microstructure. The microstructure of HARDOX 500 consists of particles of hard bainite and dispersed tempered martensite. The bainite particles are soft and form a uniform structure that adds toughness to the plate. The small particles of tempered martensite, however, are very hard and serve as an important defense against abrasion. As a result, HARDOX 500 not only offers excellent weldability but also maintains its toughness despite impacts and wear.
    
    In summary, HARDOX 500 offers superior weldability and toughness as compared to other wear plates on the market. Its combination of low alloying elements and quenched microstructure make it ideal for applications requiring both wear resistance and weldability. The steel can be welded in various methods, and the weldability of the plate is not affected by heat input. In addition, the microstructure of the steel provides good toughness and abrasion resistance.
