460N

S460N Steel Plate EN 10025 -  3: 2004

S460N – offers high yield and tensile strength with a minimum yield strength of 460 N/mm². These Steel covers weldable structural steels manufactured with a fine grain structure and supplied in the normalised condition or normalized rolled condition.

Each grade is further sub-divided based on the specified minimum value of impact energy at a particular temperature.There are four grades (S275, S355, S420 and S460) which indicate each grade’s minimum yield strength (in MPa) for plates 16 mm thick and below.N indicates temperatures not lower than -20 deg C and NL not lower than -50 deg C.

Chemical composition %   of grade   S460N (1.8901)

  • Nominal thickness =< 63(mm) CEV max = 0.53
  • Nominal thickness from 63 to 100 (mm) CEV max = 0.54
  • For long products the P and S content can be 0.005% higher
  • For railway application a maximum S content of 0.01% may be agreed at the time of inquiry and order
  • In sufficient other N-binding elements are present the minimum total Al content does not apply
  • Cu content above 0.4% may cause hot shortness during hot forming
