Specification, Chemical & Mechanical Performance

Standard : EN10025-2

Steel Grade : S355JR

Nearest Equivalent : BS4360 Gr50B; BS4360 Grade50D; BS4360 Gr50DD; DIN 17100 ST52-3; ASTM A572-50;JIS G3106 SM490; JIS 3101 SS490; ABS EH36; LRS EH36

S355 – an useful structural grade steel with a minimum yield strength of 355 N/mm².

S355 being widely used in the structural engineering and 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.

S symbol for Structural Steel

JR symbol 20 temperature impact test

J0 syambol 0 temperature impact test

J2 symbol -20 temperature impact test

 

S355JR Application
