Technical data of S420M steel

Large-thickness S420M steel, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.

Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. S420M steel, 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.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's S420M steel steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole S420M steel steel transportation industry.

Strip steel is mainly used for the manufacture of welded pipes, clamps, washers, spring blades, saw blades, blades and other fields, so the S420M steel, strip steel specifications are also relatively standardized. First, the strip width should be within 1300mm, if it is too wide, it will become a steel plate, and the machining is not allowed to be too wide, otherwise it will fail. Second, the strip steel length is not limited, and the strip steel can be coiled together after bending, reducing most of the space.
