Speaking of A572 Gr 42 CS steel carbon plate steel plates for engineering sites, the first thing people think of is wear plates. With excellent wear resistance, wear plates successfully replace traditional aluminum alloy wear plates, which can be called raw materials that are very resistant to wear at this stage. However, with the deepening of winter, the temperature is getting lower and lower, and the wear plates are not resistant to low temperature, so what aspects should be paid attention to in the winter wear plates construction?
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with A572 Gr 42 CS steel carbon plate, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
A572 Gr 42 CS steel carbon plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of A572 Gr 42 CS steel carbon plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. A572 Gr 42 CS steel carbon plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
