Application analysis of performance of European standard S690Q high strength alloy plate

1, S690Q European standard high strength board introduction

S690Q steel plate is a tempered high-strength steel plate, "S" represents its brand for the European standard standard, the corresponding national standard is Q690D high-strength structural steel. It is used for the manufacture of key components of low temperature resistance and high strength, construction machinery, mining machinery structure, etc.

2, S690Q high strength board implementation standard: EN10025-6

3, S690Q high strength board delivery status: tempering (quenching + tempering)

Note: Direct quenching and then tempering after hot rolling is considered equivalent to conventional quenching and tempering.
4, S690Q European standard high strength board characteristics

S690Q adopts controlled rolling technology, and it can be seen from the chemical composition of the steel plate that the content of harmful elements S and P is relatively low, indicating that the steel is pure and the welding performance is good.

5, S690Q European standard high strength board application range

S690Q steel plate is mainly used in the manufacture of low-temperature resistance, high-strength key components, construction machinery, mining machinery structure, etc., is a high-strength structural steel plate. It is also used in manufacturing plants, general construction and all kinds of construction machinery, such as mining and all kinds of engineering construction RIGS, shovels, electric wheel dump trucks, mining cars, excavators, loaders, bulldozers, all kinds of cranes, coal mine hydraulic support and other mechanical equipment and other structural parts.
