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.
