About S355 Common Steels
A structural grade (S) with at minimum yield strength of 355 N/mm²m, the JR designation confirms that the steel has undergone longitudinal Chary V-Notch impact testing at 27J (Joules) at room temperature. Other Charpy designations include JO, J2 and K2.
A structural grade (S) with the same minimum yield strength of 355 N/mm²m, but supplied in an ‘as rolled condition’.
As S355JR but Charpy tested at 40J (Joules) at -20°C and supplied in the normalised condition.
The above steels represent only a small example of the quality range of S355 steels available for supply from Masteel UK Limited.
