Properties of S235 steel and equivalent material
S235 steel is a commonly used designation for a type of structural steel in the European Union. It is also known as St37 in Germany and by various other names in different countries. S235 material is part of the “S” series of steel grades, which includes S235, S275, S355, etc. These grades are mainly used for structural purposes in construction and engineering. According to EN 10025 and EN 10210, S235 material is divided into the following quality grades:
EN 10025-2 :
- S235JR (1.0038) – Impact energy ≥27 Joules at room temperature 20 °C,
- S235J0 (1.0114) – Impact energy ≥ 27J at 0 °C, and
- S235J2 (1.0117) – Impact energy ≥ 27 J at -20 °C.
- S235JRC (1.0122)
- S235J0C (1.0115)
- S235J2C (1.0119)
EN 10025-5 :
- S235J0W (1.8958)
- S235J2W (1.8961)
EN 10210-1 : S235JRH (1.0039)
Meaning/Designation
S235 meaning: S means structural steel, 235 indicates that the minimum yield strength of steel is 235 MPa for steel thickness less than 16 mm. (For more information, see Designation and Meaning of Steel Names)
