01Product Overview & Specifications
EN 10025-2 S355JR is a premium non-alloy low-carbon structural steel governed by the European standard EN 10025-2:2004. It features high yield strength, excellent ductility, reliable weldability and stable room-temperature impact resistance. With balanced mechanical performance and cost-effectiveness, it has become the most widely used general structural steel in global construction and mechanical manufacturing industries.
As a core grade of the EN 10025-2 structural steel series (covering S235, S275, S355 and S450 series with JR / J0 / J2 / K2 impact grades), S355JR is universally applicable for static and dynamic load-bearing structures, supporting conventional secondary processing including cutting, bending, welding and forming.

Note: Equivalent grades match S355JR 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.
03Grade Symbol Explanation
Standard coding rules for EN 10025-2 structural steel — the designation encodes the steel family, strength level, impact grade and delivery condition.
S
S — Structural Steel
The leading letter identifies the material as non-alloy structural steel for general engineering use.
355
355 — Yield Strength
Minimum yield strength of 355 MPa at nominal thickness up to 16mm.
JR
JR — +20°C Impact
Room-temperature impact grade: 27 J Charpy V-notch impact energy at +20°C (longitudinal).
J0/J2
J0 / J2 / K2 — Low Temperature
J0 (0°C impact), J2 (−20°C impact), K2 (−20°C high toughness impact) for colder service.
AR/N
AR / N / Q&T — Delivery State
As Rolled, Normalized, Quenched & Tempered — selectable delivery conditions per design requirement.
04Chemical Composition
S355JR is semi-killed or fully killed steel with strictly controlled impurity elements, effectively avoiding brittleness and ensuring structural safety.
