Product Description
GB Q355E DIN S355K2 Carbon Steel Flat/ Plate
1: DIN S355K2 steel introduction
S355K2 belongs to the European standard low alloy high strength structural steel plate, "S" stands for structural steel, "355" stands for the specified minimum yield point (MPa), which will be reflected in its mechanical properties. "K2" means that the impact energy at -20℃ is not less than 40 J ("K" means the required 40 J and "2" means -20℃). It carries high strength, high toughness, fatigue resistance, impact resistance, wear resistance, corrosion resistance, welding and easy processing properties.
