Basic knowledge about JIS carbon steel SM490B CS plate

Grade EH36 marine steel: E is the quality grade E, H is the high-strength building material, 36 is the maximum compression, and Z is the Z-direction stretching. Grade EH36 structural steel for high-strength hull refers to the steel used for manufacturing the hull structure produced according to the requirements of the classification society. Our company mainly supply Grade EH36 hot rolled plate, JIS carbon steel SM490B CS plate, Grade EH36 angle steel bars and steel sections.

High wear resistance: fully automatic CNC stacking equipment, independent of manual JIS carbon steel SM490B CS plate welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the JIS carbon steel SM490B CS plate hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite JIS carbon steel SM490B CS plate wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

S355J2 steel plate JIS carbon steel SM490B CS 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 JIS carbon steel SM490B CS plate 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℃.
