BBN provides the composition design, production process design, microstructure and mechanical properties of the P235GH steel plate free of charge. The technical delivery conditions of the P235GH steel plate fully meet the requirements of the standard EN 10028-2:2009, and the required chemical composition and mechanical properties can be met.
The composition design principles of P235GH steel plate are:
(1) Reduce the carbon equivalent as much as possible while ensuring the strength of the P235GH steel plate, so that the P235GH steel plate has excellent welding performance;
(2) The content of alloying elements is reduced as much as possible while the performance meets the requirements of use, so that the composition of the P235GH steel plate is simple, easy to manufacture and low in cost;
(3) Reduce the content of harmful elements in the P235GH steel plate as much as possible, reduce the formation of inclusions, and further improve the low temperature impact toughness of the steel plate.
All P235GH steel plate should be ultrasonically inspected before leaving the factory. The inspection methods and quality standards should be implemented in accordance with JB 4730.3. P235GH steel plate should meet the requirements of Class I.
Just like you, 70% customers choose long-term cooperation with BBN steel not only for our good product and service quality, good reputation in the international market, but also for our experienced one-stop raw material supply and further steel processing!
