Welcome to BBN High Strength Steels Factory
Q420B material is a low-alloy high-strength structural steel. steel flat 50x10 S690QL, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.
The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy steel flat 50x10 S690QL are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.
steel flat 50x10 S690QL 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 steel flat 50x10 S690QL 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. steel flat 50x10 S690QL annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
The automobile steel coil and sheets are one of our main steel materials exported to the overseas.
