Q890D High Strength Steel Sheet(HSLA)
Q890D high strength steel sheet is a low-alloy high-strength structural steel sheet. The production execution standard is: WYJ special technical conditions.
Q890D high tensile steel plate itself not only has high strength, but also has comprehensive high-quality properties such as high toughness, fatigue resistance, impact resistance, corrosion resistance, wear resistance and easy welding and processing. Therefore, Q890D low alloy steel sheet is widely used in mining machinery and equipment, engineering machinery and equipment, heavy industry machinery, coal mining machinery, cranes, steam turbines, ultra-supercritical, steam engines, nuclear power equipment, ship equipment, bridge structures and other applications.
