What is yield strength of A387 GR.11 CL.2 pressure vessel steel sheet

Low alloy steel plate, refers to the steel plate whose alloy content is less than 3.5%. The most popular low alloy steel plate is A387 GR.11 CL.2 pressure vessel steel sheet, Q345B plate and its equivalent materials such as S355JR, A572 grade 50 and so on. Low alloy steel plate plays an important role in the construction, it must have enough strength and stability to bear the safety of the house. Low alloy steel plate is often used in large buildings with large bearing capacity and good cross-section stability, such as bridges, ships, lifting and transportation machinery, etc.

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A387 GR.11 CL.2 pressure vessel steel sheet etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, A387 GR.11 CL.2 pressure vessel steel sheet is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.
