S690QL rockwell hardness biggest 6 mills Spain

The S690QL rockwell hardness processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the S690QL rockwell hardness steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.

Bridge steel plates are steel plates specially used to build railway or highway bridges.
It is required to have high strength, toughness and bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The steel S690QL rockwell hardness for tie-welding bridges should also have good welding performance and low notch sensitivity.

we also provide the S690QL rockwell hardness welding service for customers, and our welding method, hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding and so on. And we have lots of successful S690QL rockwell hardness welding project, such as longitudinal submerged arc welding pipe, welding cross colume, prestressed truss and welding box colume.
