S690Q material equivalent hot rolled carbon steel round bar

S690QL high-strength steel is used for low temperature, high strength key components, construction machinery, mining machinery structure, etc. European standard high strength steel plate, S690Q material equivalent, manufacturing various types of construction machinery, such as mining and various types of construction drilling rig, electric shovel, electric wheel dump truck, mining truck, excavator, loader, bulldozer, various types of cranes, coal mine hydraulic supports and other structural parts.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In S690Q material equivalent, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the S690Q material equivalent, steel plates and strips used for stamping must have qualified stamping performance.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, S690Q material equivalent sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
