Chemical composition content of S275NL carbon structural steel

Posted:2021-06-30 16:46:37

S275NL is a kind of fine grain structural steel in European standard EN10025-3. The yield strength and tensile strength of S275NL carbon structural steel correspond to Q345 low alloy steel in China. NL requires the impact absorption energy test in a low temperature environment of minus -50℃, and the impact value is not less than 27J.
