EN 10025 S355 Steel
S355 steel is a European standard structural steel grade, according to EN 10025-2: 2004, material S355 is divided into 4 main quality grades:
- S355JR (1.0045),
- S355J0 (1.0553),
- S355J2 (1.0577) and
- S355K2 (1.0596).
The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.
Steel Grade S355 Meaning (Designation)
The following letters and numbers explains the steel grade S355 meaning.
- "S" is short for "structural steel"
- "355" refers to the minumum yield strength value for the flat and long steel thickness ≤ 16mm.
- "JR" means the impact energy value is minumum 27 J at room temperature (20ºC).
- "J0" can withstand the impact energy at least 27 J at 0ºC.
- "J2" related to the minumum impact energy value is 27 J at -20ºC.
- "K2" refers to the minumum impact energy value is 40 J at -20ºC.
Datasheet and Specification
Below are the tables to show the steel grade S355 datasheet including chemical composition, yield strength, tensile strength and elongation, etc. All data sheet of DIN EN 10025-2 is the same as BS EN 10025-2 and other EU member states.
