S355J2G3 Steel 1.0570 DIN St52-3N - High Yield Carbon Manganese Steel Suppliers & Factory in China
GENERAL CHARACTERISTICS
This grade of steel is carbon manganese, high yield non alloy steel. It is called S355 because of the average minimum yield for this material is 355 Mpa. As a structural steel, it has excellent strength and weldability. It can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties. S355J2G3 is generally supplied in a normalized condition.
