Which EN standard steel grade is grade 09CuPCrNi-B equivalent

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 grade 09CUPCRNI-B 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.

Management information and high efficiency. Because of the rapid flow of grade 09CUPCRNI-B goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

The advantages of flame cutting are simple cutting and low cost. The disadvantage of flame cutting is that when cutting thin plates, cutting deformation problems are prone to occur, and the materials that can be cut have certain limitations. The advantage of CNC cutting is that it can cut grade 09CUPCRNI-B and any complex parts with high cutting accuracy. The disadvantage of CNC cutting is that there are certain operational and technical requirements.
