Weldable structural steel
S235JR / 1.0038 non-alloy structural steel
S235JR is weldable structural steel to EN 10025-2. 235 MPa yield, impact toughness at room temperature. W.Nr. 1.0038 is the same family as the older St37-2.

What it is used for
Lighter steel structures, brackets and plate that are welded without special low-temperature requirements.
Limits
S355J2 when strength or −20 °C impact toughness must be documented.
Delivery
We source S235JR from European mill partners as plate, flat bar, round bar, cut to your dimensions and ship the certificate with the material. Typical condition: +AR or +N. From a single cut piece to larger lots — with no minimum charge, so you do not have to buy a full commercial length to get what you need.
Certificates and documentation
S235JR can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. On welded structures it is the analysis, the strength class and — where the standard requires it — the impact toughness that the certificate must show. EN 10204 3.1 can be supplied on a wide range of our materials, and 3.2 is ordered when the project requires third party.
Dimension programme
| Form | Range | Note |
|---|---|---|
| Round bar | Ø40–200 mm | Lighter structural bar than S355J2. |
| Flat bar | Cut to order | Flat bar. |
| Plate | 5–80 mm thickness | Ordinary structural plate. |
| Fittings | Ø12–Ø2000 mm | ASME 1/2–60″ (Ø15–Ø1524 mm). Type A and B. Not a stock statement. |
| Flanges | Ø14–Ø2000 mm | ASME 1/2–60″ (Ø15–Ø1524 mm). PN 6–400. Not a stock statement. |
Parts of the range are held by European partners; other dimensions can be sourced. The range is not a current stock status in every diameter — stock is confirmed on enquiry.
Frequently asked questions
- What is the Werkstoff number for S235JR?
- The Werkstoff number is 1.0038. The same grade may appear as S235JR, 1.0038 or both on the drawing.
- What is the AISI/SAE equivalent of S235JR?
- AISI/SAE A36 is the closest American designation. Chemistry, mechanical requirements and certificate must be checked before substituting.
- In which condition is S235JR supplied?
- Typically +AR or +N. State the condition the certificate must carry.
- Which dimensions can Industristål supply in S235JR?
- S235JR / 1.0038 as round bar typically Ø40–200 mm. Length is cut. The range is a delivery programme — not a stock statement.
- Can Industristål supply a single piece in S235JR?
- Yes. We also supply single pieces and small quantities with no minimum charge. You do not have to take a full commercial length.
- Can the material be supplied with a 3.1 certificate?
- Yes. EN 10204/3.1 can be supplied where relevant for S235JR. 3.2 is ordered before we lock the material.
