EN 1.0122 Steel S235JRC+C, S235JR+AR, S235JR+N Material Meaning & Definition

1.0122 Steel S235JRC+C, S235JR+AR, S235JR+N

S235JRC steel (EN 1.0122 material), S235JRC+C, S235JR+AR and S235JR+N are different delivery and surface conditions of S235JR steel according to the European standard EN 10025-2 and EN 10277-2 (replaced by EN 10277: 2018).

Detailed information about the S235JR material can be found in the S235JR datasheet.

Designation (Meaning & Definition)

S235JRC means that the material is suitable for cold flanging, cold forming or cold drawing.

• “S” means structural steel;
• “235” refers to the minimum yield strength (MPa) for the steel thickness ≤ 16 mm;
• “JR” indicates the quality grade related to the impact test energy values (≥ 27 J at room temperature 20 °C)
• “C” means the steel is suitable for cold flanging, cold forming or cold drawing.
• “+AR” means the steel is delivered in the condition of “as-rolled”.
• “+N” means the delivery condition of this steel is “normalizing rolling”.
• “+C” means cold work hardened.
