What is the trend of S690QL steel equivalent to grade 50 prices this winter

The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. S690QL steel equivalent to grade 50, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment,S690QL steel equivalent to grade 50. 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 S690QL steel equivalent to grade 50 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. S690QL steel equivalent to grade 50 annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.[Enterprise Spirit]: professional, honest, dedicated and innovative.[Enterprise Tenet]: provide customers with satisfactory steel products and services.[Enterprise Policy]: customer satisfaction is our pursuit.
