Q620C high strength steel
Q620C high strength low alloy steel sheet is attributed to modulated high strength structural steel plate, Q620C low alloy structural steel executive standard introduction GB/T16270 special technical conditions.
Q620C low alloy steel sheet has very good permeability, wear resistance, fatigue resistance, corrosion resistance, impact resistance, high strength, and welding easy processing and other high quality performance.
Q620C high strength steel plate is often used in the machinery manufacturing industry, such as: mining machinery, coal mining machinery, cranes, hydraulic presses, steam turbines, blades and so on.
