Hardox400 wear-resistant plate is the most commonly used wear-resistant steel plate in the market. The cost performance is high. Hardox400 has the hardness of hbw400. It is a kind of all-round wear-resistant steel. Due to its high toughness, excellent bending property and excellent welding performance, this kind of steel can be used for structures with moderate wear.
Wear resistant plate 400 can provide thickness of 2mm thin, thickness of 130mm high, general standard width of 2000mm or 2500mm, length of 5800mm or 6000mm, if it is a fixed rolling steel plate, the maximum width can reach 3350mm and the length can reach 14630mm. Its standard is en10028.
Hardox400 is divided into thin plate and thick plate according to different production process. The thickness of thin plate is 2.0 mm-8.0 mm, and the hardness range is hbw370-hbw430. The internal hardness of the plate is slightly lower than the surface hardness. However, due to the overall quenching, its low center hardness is 90% of the guaranteed surface hardness. From this we can see that the overall uniformity of humda 400 is very good, which also represents its excellent processing performance.
The thickness of thick plate is 4.0 mm-130 mm, and the hardness is also between hbw370-hbw4300. The typical yield strength of thin and thick plates is 1100mpa. The impact characteristics of Hardox400 wear-resistant plate were tested by Charpy impact test V-type 10 * 10mm specimen, and the typical impact energy was 45j / - 40 ℃. This number indicates that Hardox400 wear-resistant plate can maintain good mechanical properties at low temperature.
