Flaw detection disqualification of EN 10025-6 S460QL1 high strength steel

Steel materials EN 10025-6 S460QL1 high strength steel can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel EN 10025-6 S460QL1 high strength steel is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.

20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for EN 10025-6 S460QL1 high strength steel steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel EN 10025-6 S460QL1 high strength steel produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.
