How to prevent cracks in S690QL1 high strength steel plates cutting

904L stainless steel plate is a kind of pipe fittings, which carries out a circle of argon arc welding between the stainless steel pipe and the pipe fittings along the butt joint, usually welding. According to the edge welding part of 904L stainless steel plate, there are three types of 904L stainless steel plate: groove extension, step edge extension and no extension. The socket welding specification is generally DN15-DN100.

API 5L Gr.B steel plate is one mainly of Steel for large diameter pipes,API-Gr.B steel is manufactured using premium grade of raw material. These products S690QL1 high strength steel plates are used to flow steam, water, oil and various petrochemicals substance in various petrochemical and chemical industries. These Steel Seamless Pipes are widely appreciated for high performance and less maintenance.

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 S690QL1 high strength steel plates 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 S690QL1 high strength steel plates 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.
