S890QL steel plate temper embrittlement

The generally spoken manganese plate is low alloy high strength structural steel. This material has good weldability and can be welded by various methods. Carbon steel plate and manganese plate belong to the category of carbon structure and low-alloy structural steel. The main difference between carbon steel plate and manganese plate is that the yield strength of manganese plate is higher than that of carbon steel plate, S890QL steel plate. From the point of view of hardness, it is obvious that the hardness of manganese plate is larger than that of carbon steel plate, and the application of manganese plate is relatively wider.

The S890QL steel plate processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the S890QL steel plate steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

S890QL steel 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 S890QL steel 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. S890QL steel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
