The price of common carbon plate is relatively low compared with other kinds of steel astm a656 grade 80 welding, and it can be used in a wide range of occasions, such as construction, machinery manufacturing, etc. Therefore, carbon plate is favored by users all over the world. And because of its large demand, fast circulation, the steel suppliers and exporters would like to keep huge carbon plate stocks, and thus the delivery is very quick. We also have large quantity stock for carbon plates. And we provide further processing for the carbon plate.

BBN company has steel plates production workshops and warehouses with a total area of more than 500,000 square meters, and the total inventory of various types of steel exceeds 1 million tons. Relying on world-leading processing equipment and storage facilities, the company has strong steel production and processing capabilities, comprehensive logistics and logistics services, ensuring that it can efficiently complete more than 1 million tons of hot rolled plates processing business each year.

The final heat treatment of quenched and tempered alloy steel, astm a656 grade 80 welding is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
