What does Grade Q500qE stand for?

Q500qE grade analysis
Q500q material is a steel plate for bridge structure. There are three quality grades (D, E, F), namely Q500qD, Q500qE, and Q500qF grades represent steel plates.
Q represents the yield strength;
500 represents the yield strength value: 500MPa;
q means steel plate of bridge structure;
D, E, and F represent different quality levels. At the same time, it represents different impact temperatures, which are specifically introduced in the mechanical properties table.

 Q500qD, Q500qE, Q500qF steel mechanical properties

Application range of Q500qE steel plate:
Hot rolled steel Q500qD, Q500qE, and Q500qF plates are structural steel plates for bridges. It is required to have high strength, toughness and to withstand the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmoSPHEric corrosion resistance. The steel for tie-welding bridges should also have good welding performance and low notch sensitivity. For the production of riveted and bolt-welded road bridges and railway bridges (including cross-sea bridges), Katalor Industry's steel production technology is proficient, providing quality assurance.
