S355JR、S355J2、S355J0 、S355K2 Steel Plate

S355JR is BS EN 10025; S355JR is equivalent to the steel number of low-alloy high-strength structural steel (European standard EN10025) in China.

Chemical composition: C: ≤0.22; Si: ≤0.55; Mn: ≤1.60; P: ≤0.025; S: ≤0.025

355 refers to the yield strength of 355MPa.

The yield strength of 355MPa is equivalent to GB of Q345 often said low alloy plate.

JR said that the number has no special requirements such as cold forming, and the closest material in our country is: Q345B.

S355J2 implementation standard: EN10025, is s355j2 European standard low alloy steel plate.

Chemical composition: C: ≤0.22; Si: ≤0.55; Mn: ≤1.60; P: ≤0.025; S: ≤0.025

355 refers to the yield strength of 355MPa.

S355J2 is an ordinary European low alloy steel plate, which can be produced by ordinary medium and thick plate steel mills, and the production standard can be referred to EN10025.and the closest material in our country is: Q345D.

S355J0 is a European standard low alloy, corresponding to the domestic material Q355C,0 represents the impact temperature 0 degrees

Chemical composition of S355J0 steel plate:

C: ≤0.22; Si: ≤0.55; Mn: ≤1.60; P: ≤0.025; S: ≤0.025

355 refers to the yield strength of 355MPa.

S355J0 Implementation standard: European standard EN10025.and the closest material in our country is: Q345C.

S structure steel

Chemical composition of S355J0 steel plate:

C: ≤0.22; Si: ≤0.55; Mn: ≤1.60; P: ≤0.025; S: ≤0.025

The impact work at K2-20 ℃ is not less than 40J (K means 40J, 2 means -20℃)

S355k2 implements the European standard EN10025, similar to the domestic Q345E
