From the ship plate to our building materials, steel plate is needed everywhere in our daily life. The quality of EN 10025 S620QL high strength steel, steel plate is also related to each of us. Therefore, the quality of steel plate should be strictly controlled from manufacturer to the user. Once there are quality problems with steel plate, it is very easy to generate major events endangering people's lives.

EN 10025 S620QL high strength steel, Chinese grade 45 steel belongs to high quality carbon structural steel. The application of EN 10025 S620QL high strength steel, Chinese grade 45 steel depends on its various properties. EN 10025 S620QL high strength steel, Chinese grade 45 steel has certain toughness and plasticity, high strength and good machinability. Good comprehensive mechanical properties of Chinese grade 45 steel can be obtained by quenching and tempering treatment. Chinese grade 45 steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

Try to use EN 10025 S620QL high strength steel high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the EN 10025 S620QL high strength steel temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
