S690QL+Z35 EN 10025-6 high strength steel cold rolled strips

GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel S690QL+Z35 EN 10025-6 high strength steel products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.

S690QL+Z35 EN 10025-6 high strength steel, Q345B low alloy steel plate composition:
1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%;
2) Add manganese-based alloying elements;
3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel;
In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.

The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as S690QL+Z35 EN 10025-6 high strength steel steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of S690QL+Z35 EN 10025-6 high strength steel steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
