Q890D high strength plate
Q890D high strength steel plate is a kind of high strength structural steel plate, which is usually used in the manufacture of heavy machinery and equipment, bridges, building structures and other fields.
The tensile strength of Q890D low alloy steel sheet is very high, usually can reach more than 890MPa, can withstand large tensile force without easy fracture and deformation, to ensure the stability and safety of engineering structure.
Q890D low alloy structural steel has excellent impact toughness, when subjected to impact loads, it is not easy to fracture, and can effectively absorb the impact energy to ensure the normal operation of equipment and structures.
