The density of wear-resistant plate is higher than that of some materials, ASTM A573 Grade 70(A573 Gr 70) plate, which makes its hardness larger. The density of steel for wear-resistant plate is 7.85kg/dm cubic. After quenching, martensite structure is obtained and tempered at 450-600℃, or 350-600℃ after tempering at 650℃. Or after tempering at 650℃ and heating at 350-650℃ for a long time, the wear-resistant plate will be embrittled. If the brittle wear-resistant plate is reheated to 650℃ and then cooled quickly, the toughness can be restored, so it is also called reversible temper brittleness. High temperature temper brittleness is the increase of the transition temperature from toughness to brittleness.
