GB Q355E | DIN S355K2 Engineering Steel

 

Quick Details
 

1: DIN S355JR steel introduction

     S355JR is a low alloy high strength structural steel conforming to European standard EN 10025. S355JR steel in China is low alloy high strength structural steel with hardness of 70-80B and yield strength of 300-400MPa. And has very good processing formability and welding performance, as well as excellent low temperature toughness.

Quick Details
 

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 -20ºC is not less than 40 J ("K" means the required 40 J and "2" means -20ºC). It carries high strength, high toughness, fatigue resistance, impact resistance, wear resistance, corrosion resistance, welding and easy processing properties.
