Naming of EN 10025 S235JR
EN 10025 is a European standard specification. It consists of six parts, each dedicated to a specific steel or group of steels. The specification covers hot-rolled structural steel formed in a range of industry-standard cross-sections.
The standard specification includes general requirements, manufacturing processes and heat treatment processes.
S235JR describes non-alloy structural steels and falls in Part 2 of the EN 10025 specification.
The 'S' denotes a 'structural steel' with a yield strength of 235 MPa.
The 'JR' designation confirms that the material has undergone a Charpy V-notch impact test at 27 joules at room temperature.
