S355 – an useful structural grade steel with a minimum yield strength of 355 N/mm².
S355 being widely used in the structural engineering and important sourceconstruction industries, S355 offers high yield and tensile strength and is supplied with a variety of treatments and test options to ensure that it is a highly usable steel in your various projects.
S355 structural grade (S) carries minimum yield strength of 355 N/mm²m, the JR designation confirms that the link for yousteel has undergone longitudinal Chary V-Notch impact testing at 27J (Joules) at room temperature. Other Charpy designations include J0, J2 and K2.
S symbol for Structural Steel
JR symbol 20 temperature impact test
