The loose coil annealed acero A36 steel sheet (O.C.A) developed by the United States is a special annealing of the boiling steel sheet in an atmosphere containing water vapor and hydrogen, because annealing in this atmosphere can remove the solid solution and carbides in the steel The compound carbon in the medium suppresses the aging sensitivity and further softens the acero A36 steel plate.
We have a high-quality elite team, with a wealth of steel products resources and business experience. The company has established a perfect career development channel to provide all employees with broad job development opportunities, clear career planning, so that the potential can be fully explored, talent can be fully exploited, and a platform for employees to realize the value of life can be built, so as to realize the common growth and development with employees in the long-term development of the company.
Q345E steel is low-alloy high-strength steel with good low-temperature impact properties. The grade of Q345E steel is composed of three parts: Chinese phonetic alphabet representing yield strength, yield strength value and quality grade symbol. Where: Q is the yield strength; 345 is the yield strength value in MPa; E is the grade (passing the - 40 degree impact test). acero A36, Q345E steel is mainly used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, power stations, workshops, low-temperature pressure vessels, etc.
