Hot Rolled Alloy Steel Plate Grade Q345ND EN10025 S355J2+ N ST52-3N Equivalent
S355J2+N steel is one grade in EN10025-2 with low alloy.S355J2+N (minimum yield strength 355 MPa, Tensile 470 to 630 MPa,+N means plus Normalized when rolling,J2 means doing charpy V-notch impacting test @ -20 ℃).
Firstly we suggest steel grade equivalent S355J2+N is ship steel plate ASTM A131 GR.DH36 (minimum yield strength 355 MPa, Tensile 490 to 620 Mpa, heat treatment under normalized or TMCP, charpy V-notch impacting test @ -20 ℃).Then ASTM A131 Gr.EH36 (minimum yield strength 355 MPa, Tensile 490 to 620 Mpa, heat treatment under normalized or TMCP, charpy V-notch impacting test @ -40 ℃) is also ok and even better than S355J2+N.
The same techincals as A131 GR.DH36 and EH36,ABS Grade DH36 and ABS Grade EH36 are both ok for replacing of S355J2+N.
Second we can suggest you choose alloy structural steel ASTM A572Gr50 (minimum yield strength 345 MPa, Tensile above 450 MPa).Of course adding techincals Normalized heat treatment and Charpy V-notch impacting test -20 centigrade for A572Gr50 when ordered.
Besides,DIN 17100 St52-3 N (minimum yield strength 345 MPa, Tensile above 490-630 MPa) is also one low alloy steel. GB/T1591 Q345D (minimum yield strength 345 MPa,Tensile above 470-630 MPa,D meas done Charpy V-notch impacting at minus 20 centigrade)
