What is S235J0?

S235J0 (1.0114) is a general-purpose non-alloy structural steel to EN 10025-2, the J0 quality guaranteeing 27 J Charpy impact energy at 0 °C. It is the default low-cost choice for welded and bolted structures, supplied as hot-rolled sections and plate, normalized, cold-drawn bar and hot-dip galvanized product, with 245 MPa yield, 420 MPa tensile, 28 % elongation and 120 HB. Strength is modest and the steel has no corrosion resistance, so coating is mandatory outdoors. Use S235J2 for guaranteed toughness at -20 °C, or S275J0 where higher load capacity is needed. S235J0 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,450°C (2,642 °F). S235J0 has a yield strength of 245 MPa (35.5 ksi) and a tensile strength of 420 MPa (60.9 ksi) — weaker than 95% of steel grades. Elongation at break is 28% and the elastic modulus is 210 GPa (30.5 Msi).

Working with S235J0

Is S235J0 easy to machine?

Soft and gummy — use sharp positive-rake tools, generous coolant and moderate speeds to avoid built-up edge; cold-drawn bar chips better than as-rolled.

Can S235J0 be welded?

Excellent with SMAW/GMAW/FCAW/SAW using E7018/ER70S-6 class consumables; CEV ≤0.35 means no preheat below ~30 mm, keep hydrogen low on thick restrained joints.

Can S235J0 be formed, bent or molded?

Readily cold bent, rolled and press-braked (typical minimum bend radius 0.5–1.5 t, transverse to rolling direction preferred); hot forms easily at 900–1200 °C.

What surface finishes work on S235J0?

No anodizing; protect by shot-blast + zinc-rich primer/paint, hot-dip galvanizing or phosphate + e-coat — bare surfaces rust within days outdoors.

S235J0 — frequently asked

What is S235J0 used for?

S235J0 is typically used for structural steel beams, building frames, bridges and general fabrication. In short: low-cost weldable structural steel; 27 J toughness at 0 °C; excellent cold formability.

What is the yield strength of S235J0?

S235J0 has a typical yield strength of 245 MPa (35.5 ksi) and a tensile strength of 420 MPa (60.9 ksi) — weaker than 95% of steel grades. Strength varies by condition: see the 3 listed tempers.

Is S235J0 easy to machine?

Reasonably — machinability is rated good (60/100, better than 83% of steel grades). Soft and gummy — use sharp positive-rake tools, generous coolant and moderate speeds to avoid built-up edge; cold-drawn bar chips better than as-rolled.

Can S235J0 be welded?

Yes — weldability is rated excellent (95/100). Excellent with SMAW/GMAW/FCAW/SAW using E7018/ER70S-6 class consumables; CEV ≤0.35 means no preheat below ~30 mm, keep hydrogen low on thick restrained joints.

What surface finishes work on S235J0?

No anodizing; protect by shot-blast + zinc-rich primer/paint, hot-dip galvanizing or phosphate + e-coat — bare surfaces rust within days outdoors.

What is the maximum service temperature of S235J0?

S235J0 is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between S235J0 +AR and S235J0-CD?

+AR is the default condition — standard, cheapest stock condition for plate, sections and merchant bar in general welded structures. CD: pick for close-tolerance shafts, pins and machined parts where the drawn surface and higher strength are wanted. Yield strength is 245 MPa in +AR versus 420 MPa in CD.

How much does S235J0 cost?
