Whose hardness is higher between No.20 steel and No.45 steel, P355GH steel used for petroleum? Both No.20 steel and No.45 steel belong to high-quality carbon structural steel. According to the characteristics of high-quality carbon structural steel, its carbon content determines the performance of the steel. The higher the carbon content, the higher the hardness and strength of the steel, the lower the plasticity and toughness. The carbon content of No.20 steel and No.45 steel are 0.20% and 0.45% respectively, which shows that the hardness of No.45 steel is higher under the same process.

The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the p355gh steel used for petroleum, alloy steel is very high, it is not easy to break and can be used for a long time.

The correct choice of billet type, section shape, size and weight are of great significance to p355gh steel used for petroleum steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The p355gh steel used for petroleum rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
