Product characteristics
Reliable performance
Under alternating loads, this steel plate maintains stable properties and reduces the risk of cracking and fracture due to fatigue. This is important for equipment subjected to cyclic loads.
Heat treatability
A516Gr70 steel plate can be further improved through heat treatment processes such as normalising and tempering, such as improving toughness and removing internal stresses. Such properties can meet more stringent engineering requirements.
Economy
Despite the excellent performance of A516Gr70 steel plate, its cost is relatively reasonable. Therefore, this steel plate is a preferred product for many companies in several industrial fields.
Good processing performance
Steel plate is easy to cut, bend, stamping and other processing operations, can meet the needs of a variety of complex shapes and structures. This effectively reduces processing costs and increases productivity.
Excellent corrosion resistance
This steel plate has a tight grain structure and uniform chemical composition. This helps to resist various corrosive media and improves the service life and safety of the equipment.
Good Toughness
This steel plate not only exhibits good toughness at room temperature, but also maintains sufficient toughness at low temperatures. This is important to prevent brittle fracture in low temperature environment.
