S355 steel is a European standard structural steel grade, according to EN 10025-2: 2004, material S355 is divided into 4 main quality grades:
The properties of structural steel S355 is better than steel S235 and S275 in yield strength and tensile strength.
The following letters and numbers explains the steel grade S355 meaning.
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.
The datasheet below shows grade S355 steel chemical composition.
