Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the A572 grade 42 ms steel project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of A572 grade 42 ms steel customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
A572 grade 42 ms steel 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 grade 42 ms steel 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 grade 42 ms steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
