NV D36 ore carrier steel Checkered Steel Plate

Q345B material is a low-carbon alloy steel (c <020%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa It has good comprehensive mechanical properties and technological performance In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness,NV D36 ore carrier steel.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

NV D36 ore carrier steel,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℃.
