What harm does the excessive weld height of S690Q steel plate bring

How to quickly judge whether the price of S690Q steel plate, weathering steel plate is reasonable? What are the factors influencing the price quotation of S690Q steel plate, weathering steel plate? First of all, the material composition of weathering steel plate is different, and the corresponding performance and price are also different. Therefore, when we talk about the price of S690Q steel plate, weathering steel plate, we should first make clear of the material composition. Secondly, the specification especially the thickness of the S690Q steel plate, weathering steel plate will affect the quotation. Generally, the thicker the weathering steel plate, the higher the price.

Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, S690Q steel plate and so on.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched S690Q steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of S690Q steel plate during tempering, while tempering determines the performance and life of the workpiece.
