S890 steel is a quenched and tempered high-strength steel plate, the series grades are S890Q, S890QL, S890QL1. S890Q, S890QL, S890QL1 steel,shipbuilding material KE MS steel plate plates, where S means structural steel, Q means that the impact temperature of the steel plate is -20°C, and QL means that the impact temperature of the steel plate is -50°C. Then guess what QL1 stands for. QL1 means that the impact temperature of the steel plate is -60°C, and 890 means that the thickness is £50mm.
The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. shipbuilding material KE MS steel plate, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.
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 shipbuilding material KE MS steel plate 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 shipbuilding material KE MS steel plate 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.
