Q235B carbon steel plate sheet black iron plate

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched Q235B carbon steel plate sheet increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of Q235B carbon steel plate sheet during tempering, while tempering determines the performance and life of the workpiece.

The advantages of Q235B carbon steel plate sheet, medium and thick boiling steel plate: The surface is relatively smooth, the quality is good, and it is easy to process. Because medium and thick boiling steel plate does not have concentrated shrinkage holes, the amount of deoxidizer is small, and boiling steel plate price is lower than other steel plates. Disadvantages of medium and thick boiling steel plate: it has a lot of gas content and impurities, it is not easy to weld, and its bearing capacity is worse than other steel plates, so it is not suitable for parts that need to bear gravity.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate Q235B carbon steel plate sheet for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 Q235B carbon steel plate sheet and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
