SA283 Gr D carbon steel plate sheet plate retest

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel SA283 Gr D carbon steel plate sheet surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

Participating tenders with clients is part of our SA283 Gr D carbon steel plate sheet business. Every year, we support a lot of clients to win tenders and supply steel materials to their govenment progects or state owned enterprise. Until now, we have built SA283 Gr D carbon steel plate sheet long-term cooperation for many govermental departments of different countries such as Peru, Bangladesh, Indonesia, Egypt, Qatar, etc.. And we have built certain influence and credibility on the International market.

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of SA283 Gr D carbon steel plate sheet, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.
