S355JR steel plate is a low-alloy high-strength structural steel that complies with European standard EN10025. Among them, 355 refers to the yield strength of 355MPa. The yield strength of 355MPa is equivalent to GB's Q345 steel plate, which is often called a low alloy plate.
S355JR steel plate performance standard: EN10025-3: 2004
Chemical composition of S355JR steel plate:
C:≤0.22;
Si:≤0.55;
Mn:≤1.60;
P:≤0.025;
