Structural steel for bridges is mainly used to make riveted and bolted welded bridge steel structures such as highway bridges, railway bridges, sea-crossing bridges, overpasses, viaducts, and large mechanical bridge cranes. EN 10025-6 high strength steel S550QL1, E grade bridge steel is suitable for low temperature and severe cold environment or bridge structural parts that are subjected to dynamic loads and the stress conditions of components are very complex and harsh.

How to distinguish between hot rolled and cold rolled process?
The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, EN 10025-6 high strength steel S550QL1, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

EN 10025-6 high strength steel S550QL1, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.
