ASTM A572 steel material BBNsteel lifts Jan H-beam prices by $96/t

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of ASTM A572 steel material service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

The elongation of low alloy high strength steel is 15% - 23%, and the impact absorption energy is more than 34J at room temperature. The ASTM A572 steel material, low alloy high strength steel has good plasticity and impact resistance, which can avoid brittle fracture during impact, and make cold bending and welding easy. In addition, the brittle transition temperature of low alloy high strength steel is low, and the absorbed work value of Grade E steel is not less than 27J at - 40℃. This is of great significance to the engineering components and transportation tools such as vehicles, ships, offshore oil platforms, containers, bridges and so on.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image ASTM A572 steel material processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the ASTM A572 steel material steel plate.

"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and ASTM A572 steel material product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."
