Working with S235J0-CD

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-CD — frequently asked

What is S235J0-CD used for?

S235J0-CD 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-CD?

S235J0-CD has a typical yield strength of 420 MPa (60.9 ksi) and a tensile strength of 500 MPa (72.5 ksi) — weaker than 53% of steel grades. Strength varies by condition: see the 3 listed tempers.

Is S235J0-CD easy to machine?

Reasonably — machinability is rated good (68/100, better than 95% 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-CD be welded?

Yes — weldability is rated excellent (90/100). 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-CD?

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

Can S235J0-CD 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 is the maximum service temperature of S235J0-CD?

S235J0-CD is rated for continuous use to about 300°C (572 °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.
