Q345 S235 L Angle Channel

Q345 Steel is a type of low-alloy steel, that is used in the manufacturing of bridges, buildings, and other structures. It has a yield strength of 345 MPa and tensile strength of 470-660 MPa. S235 grade steel is a readily weldable low carbon manganese steel with good impact resistance (including in sub-zero temperatures). This material is commonly supplied in the untreated or normalised condition and is available in several variations (denoted by additional letters and/or digits), which offer slight modifications of chemical composition and mechanical properties.

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.
