Note: Equivalent grades match S235JR in general strength level and weldability, yet minor differences exist in chemical composition limits, impact requirements, tolerances and test conditions. For critical or long-cycle projects, please verify detailed project specifications before cross-standard replacement.
03Symbol Interpretation of EN 10025-2:2004
The EN 10025-2 designation encodes the steel family, the minimum yield strength and the required impact toughness level — three letters and numbers that tell you exactly what you are buying.
S
S — Structural Steel
The leading letter identifies the material as non-alloy structural steel for general engineering use.
235
235 — Yield Strength
Minimum yield strength (ReH) of 235 MPa at nominal thickness up to 16mm.
JR
JR — +20°C Toughness
Longitudinal Charpy V-notch impact energy of 27 J at +20°C.
J0
J0 — 0°C Toughness
Longitudinal Charpy V-notch impact energy of 27 J at 0°C.
J2
J2 — −20°C Toughness
Longitudinal Charpy V-notch impact energy of 27 J at −20°C.
04Chemical Composition & Carbon Equivalent
Controlled non-alloy chemistry (material No. 1.0038, semi-killed or killed) ensures consistent weldability, formability and batch-to-batch stability.

For long products, P and S content may be 0.005% higher than the standard limit
By special agreement, max S of long products may be raised by 0.015% for machinability (sulfide morphology modified, Ca ≥0.0020%)
The N limit does not apply when total Al ≥0.015% or acid-soluble Al ≥0.013%, or with other sufficient nitrogen-binding elements
Cu content above 0.45% may cause hot shortness during hot forming
Any additionally added elements shall be recorded in the inspection document
Thickness >150 mm: maximum C content is 0.22%
Cold roll forming grades: maximum C content is 0.24%
Thickness >30 mm: maximum C content is 0.24%
Note: Values above are specified limits per EN 10025-2 (heat analysis). The exact heat analysis and CEV of each plate are stated in its Mill Test Certificate (MTC) supplied with delivery.
