Whose hardness is higher between No.20 steel and No.45 steel, S355J2G1W steel plate for construction machinery? 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.
We exported 2150 Tons SG295 steel coils to Sudan. The Sudan customer is LPG cylinder manufacturer. Before our cooperation, he usually purchased SG295 steel coils from UAE and Turkey. And he got to know our company through our regular customers in Uganda, UAE, and his friends in China. Then he gave us the order. We invited the customer to visit us before contract, but he insisted to visit us when the S355J2G1W steel plate for construction machinery goods are finished production. After inspecting the size, package in workshop and witness the lab test for the SG295 steel coils, the customer was very satisfied to our quality control and professional arrangement.
Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, S355J2G1W steel plate for construction machinery and so on.
