Normalizing temperature of 19Mn6 pressure vessel steel sheet

19Mn6 pressure vessel steel sheet 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 19Mn6 pressure vessel steel sheet 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. 19Mn6 pressure vessel steel sheet annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

The defects of 19Mn6 pressure vessel steel sheet, wear-resistant plate in rolling process can be divided into raw material defects, surface spot defects, plate shape defects and edge defects. The so-called raw material defects refer to some defects caused by raw materials and kept or remained in the cold rolling process. The defects of raw materials usually include bubbles, inclusions, iron sheet pressing in, raw material scratches and roll marks. The stain defect of wear-resistant plate is mainly caused by the oil on the surface of strip steel and the iron powder produced during rolling, which is left on the surface of strip steel after rolling.
