Good quality S460NL carbon steel plate sheet with low cost

The quality of carbon steel is distinguished by the amount of sulfur (s) and phosphorus (P) in the steel. When the S460NL carbon steel plate sheet sulfur content in carbon steel is not more than 0.050% and the phosphorus content is not more than 0.045%, it is ordinary carbon steel; when the sulfur content and phosphorus content in carbon steel are less than 0.040%, it is high-quality carbon steel; when the S460NL carbon steel plate sheet sulfur content in carbon steel is less than 0.030% and the phosphorus content is less than 0.035%, it is high-quality carbon steel.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the S460NL carbon steel plate sheet plate should be derusted before cutting.

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This S460NL carbon steel plate sheet production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate S460NL carbon steel plate sheet size.
