Characteristics
S355 – an useful structural grade steel with a minimum yield strength of 355 N/mm². S symbol for Structural Steel
JR symbol 20 temperature impact test
S355 being widely used in the structural engineering and construction 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 steel has undergone longitudinal Chary V-Notch impact testing at 27J (Joules) at room temperature. Other Charpy designations include J0, J2 and K2.
