XAR500 wear resistance sheet

Germany Thyssen Krupp Stahl AG (ThyssenKrupp Steel, hereinafter referred to as TKS) began in the mid-1960s with high wear resistance of special structural steel, quenched or quenched and tempered heat treatment, with dense Martensitic or martensitic-bainitic microstructures. The thickness of the steel plate produced up to 100mm. In addition to the traditional XAR 400, XAR 450, and XAR 500 levels, TKS has successfully developed three new levels - XAR 300 normalized steel for low and medium wear environments, XAR 400W for higher temperatures, and higher Wear requirements of the super-hard XAR 600. In this way, the hardness of the available steel plate covers a range of 300 to 600 HB, providing a suitable solution for almost any environment. In all levels, the most commonly used is the XAR 400 with a hardness of 400HB, which lasts up to 5 times longer than conventional structural steel plates.

For quenched or quenched and tempered XAR steels, since the highest hardness of the steel is proportional to its carbon content, it is essential to maintain a certain carbon content in the steel to obtain the required high hardness. For example, the nominal hardness of 400HB steel, to keep about 0.14% of carbon, while adding Mo, Ni, B to ensure that the steel plate inside and outside the performance balance. Also note that all XAR steels contain less than 1.5% Cr. Various types of wear tests have shown that it is very effective in improving the wear resistance of steel, especially in the wear resistance of slightly acidic media. The special wear-resistant structural steel XAR300 has a very good surface quality and is especially suitable for thermoforming applications.

XAR wear-resistant steels are high-tech materials that combine perfectly high hardness, excellent toughness, low alloy content, and outstanding processability to make them ideal for a wide range of applications.

The XAR500 is a special structural steel with high wear resistance. This wearable special-purpose structural steel has an average hardness of 500 HB, high hardness and good toughness, and the structure made of the steel is stronger, lighter and can withstand impact load.

Uses for wear and tear - exposed structures such as shovels, shields for mining machines and bulldozers, shell walls, supports and stiffeners; cutting boards, linings for dump truck bodies, wear plates; mixing and conveying elements , Chutes, screens, machine tools, crushers and shredders, scrap briquetting presses, shovels, pavers and agricultural machinery.
