ASME SA 53 seamless pipe is a low carbon A709 Gr 50W low alloy steel sheet steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized A709 Gr 50W low alloy steel sheet steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.
The company adopts the A709 Gr 50W low alloy steel sheet international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety A709 Gr 50W low alloy steel sheet management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.
Non-destructive flaw detection of steel plates is a test method for inspecting the A709 Gr 50W low alloy steel sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used A709 Gr 50W low alloy steel sheet steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, A709 Gr 50W low alloy steel sheet. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%.
