Quenching is a common heat treatment process. It is the metal heat treatment process in which the BV grade B barge carrier steel metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between BV grade B barge carrier steel strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as BV grade B barge carrier steel. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.
EH500 steel plates and EH550 steel plates are both ultra-high-strength structural steel plates for ships and oceans. The addition of microalloying elements can not only improve the strength, compensate for the strength loss caused by the reduction of carbon equivalent, but also improve the welding performance, mechanical properties and process performance of the steel BV grade B barge carrier steel. Due to the use environment requirements of EH500 steel plate and EH550 steel plate, it can meet the requirements of high strength, high toughness, high welding performance, and thickness direction performance.
