Forecast of SA709 Gr 50 carbon steel plate sheet building materials price

SA709 Gr 50 carbon steel plate sheet, S690QL steel plate is a quenched and tempered high-strength steel plate. "S" means that its grade is European standard, and the corresponding Chinese standard is Q690E high-strength structural steel. S690QL steel plate is used in the manufacture of low temperature resistant, high-strength key components, construction machinery, mining machinery structures, etc.S690QL steel plate executive standard: EN10025-6.

Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. SA709 Gr 50 carbon steel plate sheet, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.

X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This SA709 Gr 50 carbon steel plate sheet method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008.
