S355G10 + M steel plate is for marine engineering. "S" indicates structural steel, "355" indicates minimum yield strength of steel plate, and "G10" indicates mechanical function test that imitates post-weld heat treatment. "M" indicates control rolling. S355G10 + M plate is structural steel for marine engineering and belongs to European standard high-strength structural steel. S355G10 + M steel plate has good mechanical function, welding function and technological function.
Compared with carbon steel, alloy steel has higher strength, better heat resistance, better low temperature resistance, better corrosion resistance and other advantages. Some of its work environment can not be adapted by carbon steel. Therefore, alloy steel is a common and important material in pressure pipeline. Low alloy steel, A514 grade Q high strength steel plate quenched and tempered steel, stainless steel, heat-resistant steel and low temperature steel are commonly used in pressure pipes.
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 A514 grade Q high strength 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 A514 grade Q high strength 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.
The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products A514 grade Q high strength steel plate more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users".
