Carbon Steel SM490YB Plate for steel pipe

Steel SM490YB Plate,12Cr1MoV alloy plate is widely used in superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power plant boiler. At 580 ℃, 12Cr1MoV alloy plate still has high thermal strength, oxidation resistance and high endurance plasticity. The production process of and 12Cr1MoV alloy plate is simple and the welding performance is good, but it is sensitive to the normalizing cooling rate. Pearlite spheroidization will occur after long-term use of 12Cr1MoV alloy plate at 580 ℃.

Steel SM490YB Plate,Looking to the future, our company will make its main business more competitive while carrying out diversified, extensive, green and harmonious development modes, so as to be the most competitive stainless steel Steel SM490YB Plate producer in the world as well as a worldwide first-class enterprise. With ten years cooperation with these big mills, now we are the agent of super stainless steel mills in China.

Steel SM490YB Plate,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 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 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.

There is a silo technology R&D center in our company with many experts. Our technical backbones go abroad to study advanced technologies regularly to make our technology and products leading in the world. We provide our customers with high-quality steel plates, the excellent quality from specialty.
