The difference between alloy steel plate and carbon steel has the following points. First, the hardenability of carbon steel is low, and the maximum diameter of water quenching of carbon steel is only 10 mm to 20 mm; second, the strength of carbon steel is only 235 MPa, while that of alloy steel is more than 360 MPa. Third, carbon steel has poor tempering stability. In order to ensure high strength, low tempering is used for carbon steel during quenching and tempering treatment, so the toughness of the carbon steel is insufficient. Fourth, the corrosion resistance, low heat resistance, and wear resistance of carbon steel cannot be compared with alloy steel, A572 grade 60 CS steel carbon plate.

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, A572 grade 60 CS steel carbon plate, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.
Last week (November 7~November 13), the price of imported iron ore increased overall. The price of external disks rose rapidly, and fell slightly towards the end of last week, and the spot price of the port increased. The price increase of iron ore is more driven by the price increase in the steel market. From the perspective of iron ore fundamentals, iron ore inventories in major ports continue to rise rapidly, steel mills are generally willing to purchase, and it is difficult for prices to continue to rise.
