Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. chemical composition of NM450, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.
Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, chemical composition of NM450 quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.
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 chemical composition of NM450 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.
