Supply the A573 Gr 70 chemical composition available BBN ex-stock list

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality A573 Gr 70 chemical composition, efficient and fast services. Facing the future, adhere to independent innovation.

A573 Gr 70 chemical composition, Wear-resistant steel plate has good connection performance:
The base material of the wear-resistant steel plate is ordinary Q235 steel plate, which ensures the toughness and plasticity of the wear-resistant steel plate, and provides strength against external forces. Wear-resistant steel plate can be connected with other structures by various methods such as welding, plug welding, and bolt connection. The connection is firm, not easy to fall off, and the connection mode is more rich than other materials.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the A573 Gr 70 chemical composition rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of A573 Gr 70 chemical composition steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

We supply 5800 tons A53 Gr B ERW pipes to Qatar for Qatar Integrated Railway Project - Green Line. This is the first Metro Line in Qatar, and it is located in Doha. We got the order by tender, launched by the Qatar Railways Company for designing, construction and completion of Green Line Project. Before putting order, a delegation from the A573 Gr 70 chemical composition project side visited us and several other famous steel pipe mills in China for 15 days. Finally, we were chosen and finished the task exceeding their expectations.
