Q620D High-strength Steel
Q620D Low Alloy Steel Plate Products Description
Features of Q620D low alloy steel sheet
High toughness: When impacted or bent, Q620D high strength steel plate can maintain good toughness and is not easy to break.
Impact resistance: Q620D high strength alloy steel can withstand large impact loads to ensure the safety of the structure, especially in a low temperature environment of -20℃, it can still maintain good impact toughness.
Other properties: Q620D low alloy steel plate also has certain corrosion resistance, wear resistance, and good welding and processing performance.
Q620D high strength steel sheet is widely used in many fields such as machinery manufacturing and engineering construction, such as heavy industry machinery, engineering machinery, chemical machinery, nuclear power equipment, bridge equipment, port machinery, ship equipment, etc.
