S275N steel plate is a kind weldable fine grain structural steel which shall be under normalized or normalized rolled delivery condition.Generally
The steel grades in EN 10025-3,S275N,S275NL,S355N and S355NL shall be classified as non-alloy quality steels,and S420N,S420NL,S460N and S460NL shall be classified as alloy special steels according to EN 10020.
For the name of S275N steel plate,S is for structural steel,275 is the minimum yield strength value for S275N when rolling,L is for low temperature impacting test under minus 20 centigrade.
