Generally, the S355J2 wear-resistant plates we use are made of a variety of alloys, and some metal elements are added. High-strength plates are heavier. We can reduce the quality of the wear-resistant plates through special treatment. So that the structure is lightened, the force of rain water on the wear-resistant plates will be weakened, and the damage to the wear-resistant steel plate will be reduced.

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 58 carbon structural steel 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 S355J2 carbon structural steel 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.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
