No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than bs EN 10025-6-S690QL. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel bs EN 10025-6-S690QL is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

"In year 2014, we participate Bangladesh national railway tender for steel plate making train carriage. We finally got the order 1000 tons and it took us 40 days to produce all the plates. The client gave very high comments to our service and bs EN 10025-6-S690QL product quality.In year 2015, we won another tender for 1200 tons B480GNQR steel coils in Bangladesh, which you can find in the steel coil part."

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. bs EN 10025-6-S690QL, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
