HARDOX400 Wear-Resistant Plate Description

HARDOX400 Wear-Resistant Plate is a high-strength wear-resistant steel plate with a hardness of 400HBW, HARDOX400 steel has high mechanical strength, and its mechanical properties are 3-5 times that of ordinary low-alloy steel plates, which can significantly improve the wear resistance of mechanical-related parts, so HARDOX400 abrasion resistant steel can be Improve the service life of machinery and reduce production costs. The surface hardness of HARD0X400 usually reaches 370~430HBW. Due to its high toughness, excellent welding performance and bending performance, it is widely used in structures with moderate wear, such as construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery, etc. Product parts; can be used to manufacture buckets, loaders, dump trucks, crushers, edge plates, side edge plates, blades, crusher liners, blades and various wear-resistant liners, etc.

The chemical composition of HARDOX400 Abrasion resistant steel plate is mainly carbon and chromium. Hardox400 steel can be formed by free bending or curling. It has good weldability and can withstand the wear of rolling contact and high surface pressure. HARDOX400 wear-resistant steel plate can be used for extreme Minimize the cost caused by the wear and tear of structural components. The delivery state of HARDOX400 wear-resistant steel plate is quenching. Open flat without primer, for shear or thermal cut edges. The surface of the plate is pre-treated with red anti-rust paint, and the edges are sheared or eagerly cut. Hardox400 wear plate obtains its mechanical properties by quenching (if necessary, tempering after quenching). However, after the steel plate is used or the preheating temperature exceeds 250°C, the performance cannot be guaranteed to be the same as that specified in the delivery conditions. Hardox400 does not require any further heat treatment.

SSAB Hardox400 wear-resistant plate is a special structural steel plate with extremely high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the corresponding steel plate. Hardox400 wear-resistant special structural steel plate is usually quenched or quenched and tempered , with excellent martensite or martensite-bainite structure. In addition, the steel plate contains a certain proportion of molybdenum, nickel, and boron alloy content to ensure uniform physical and mechanical properties in the thickness direction. In addition, a large number of wear tests have proved that the chromium content of about 1.5% in hardox series wear-resistant steel plates can more effectively improve wear resistance, especially in weak acidic media.
