High-yield Strength Hot Coils for Cold Forming

High-yield Strength Hot Coils for Cold Forming can significantly reduce the design thickness of steel plates. This change reduces the weight of the structure. In addition, this series of steel also has the following characteristics:

• Good formability. Different grades of these products can be cold formed.
• Excellent welding performance. These products have low welding crack sensitivity and the good performance of welding joint.
• Good toughness at low temperature.

Application

The cold-formed steel series has been widely used in the construction machinery, container manufacturing, and automotive structural industries. At present, we have designed and developed a series of high-strength cold-formed steel with excellent low-temperature toughness, such as S550MC, S600MC, S650MC, and S700MC. In addition, this series of high-strength low-alloy structural steels has good weldability and cold forming performance.

In addition, this series of high-strength structural steels adopts advanced melting technology, niobium titanium microalloying treatment, and precise controlled rolling and controlled cooling technology design, forming a bainite microstructure containing a small amount of ferrite. The manufacturing process and microstructure ensure stable and reliable mechanical, processing, and quality performance.
