Q500D high strength alloy steel belongs to low alloy high strength
structural steel plate, which implements GB/T related standards,
has good impact toughness and is widely used in many fields.
Q500D high strength steel sheet has good processing performance,
easy to cut, bend and form; excellent welding performance and high
weld quality. At the same time, Q500D high strength steel plate
also has wear resistance, weather resistance, fatigue resistance
and good high temperature resistance.
Q500E alloy steel plate is a low-alloy structural steel plate with
high strength and high toughness. The "Q" in Q500E high-strength
steel plate stands for yield strength, "500" means the yield
strength is not less than 500MPa, and "E" stands for excellent
impact toughness and welding performance.
The chemical composition of Q500E high strength sheet metal is
stable, mainly including carbon, silicon, manganese and other
elements, and may contain trace amounts of chromium, nickel, etc.
to improve performance.
Q500E high tensile alloy steel is widely used in bridges,
vehicles, ships, buildings and engineering machinery, etc., which
can meet the use requirements under complex stress conditions and
improve the stability and durability of the structure.
