The iron oxide skin on surface of SA572 grade 50 carbon steel material

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of SA572 grade 50 carbon steel material service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

For SA572 grade 50 carbon steel material ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B SA572 grade 50 carbon steel material is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, SA572 grade 50 carbon steel material, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

S355J2 steel plate SA572 grade 50 carbon steel material 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 SA572 grade 50 carbon steel material 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℃.
