DIN 17102 StE315 Steel Plate | StE315 Fine Grain Steel
What is DIN 17102 StE315 Steel?
DIN 17102 StE315, also written StE 315, STE315, DIN17102 StE315 and StE315 steel plate, is a weldable normalized fine-grain structural steel under DIN 17102. StE means the basic / room-temperature quality. Yield in the thin band is 315 MPa. Tensile at ≤70 mm is typically 440–590 MPa. This grade sits between StE285 and StE355. It is not the P275N line and not the P355N line. Buyers still name it when an old German drawing kept the 315 step instead of jumping to 355. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade. Plate is produced to DIN 17102 and shipped to buyers in the USA, Europe, Middle East and Southeast Asia.
A purchase order that only says “315 fine grain” is incomplete. Write DIN 17102 StE315. Do not ship StE285 against a StE315 drawing. Do not ship StE355 against a StE315 drawing and call 40 MPa extra yield a free upgrade. The calculation used 315 MPa, not 355 MPa.
DIN 17102 is a legacy specification. New European work usually picks S275N / P275N or S355N / P355N under EN 10025-3. There is no single EN name as clean as StE285 → P275N or StE355 → P355N. Replacement projects still name StE315 when the original German file stays on that number.
This page is not DIN 17100 St52-3. DIN 17100 is ordinary structural steel. DIN 17102 is fine-grain, killed, normally normalized. This page is not SA516 Gr.70. Grade 70 is ASME carbon vessel plate at 260 MPa yield. StE315 is 315 MPa yield fine-grain plate. It is not ASTM A36 steel plate. It is not QT alloy under ASME SA387 or ASME SA543.

Chemical Composition
DIN 17102 StE315 / StE 315 uses a manganese band between the 285 and 355 families.
Heat Analysis — DIN 17102 StE315 (typical cast / ladle limits)
| Element | Heat Analysis (%) |
|---|---|
| Carbon (C), max | 0.18 |
| Silicon (Si), max | 0.40 |
| Manganese (Mn) | 0.70 – 1.50 |
| Phosphorus (P), max | 0.035 |
| Sulfur (S), max | 0.030 |
| Nitrogen (N), max | 0.020 |
| Aluminium (Al), min (total, when used for grain) | 0.020 |
| Chromium (Cr), max | 0.30 |
| Copper (Cu), max | 0.20 |
| Molybdenum (Mo), max | 0.08 |
| Nickel (Ni), max | 0.30 |
| Niobium (Nb), max | 0.05 |
| Nb + Ti + V, max | 0.12 |
StE285 manganese is 0.60–1.40. StE355 manganese is 0.90–1.65. Do not ship a 355 heat as StE315 because a coupon came in low. TStE315 and EStE315 tighten P and S. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it. If a Houston, Rotterdam or Jebel Ali specification tightens P and S, write that on the order.
Mechanical Properties
Yield starts at 315 MPa at ≤16 mm and falls as thickness rises.
Tensile and Yield — DIN 17102 StE315 (typical published bands)
| Thickness (mm) | Yield ReH min (MPa) | Tensile Rm (MPa) |
|---|---|---|
| ≤16 | 315 | 440 – 590 (≤70 mm band) |
| 16 – 35 | 305 | 440 – 590 |
| 35 – 50 | 295 | 440 – 590 |
| 50 – 70 | 285 | 440 – 590 |
| 70 – 100 | 275 | 430 – 580 |
| 100 – 150 | 265 | 410 – 570 |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Do not quote 315 MPa yield on a 80 mm plate. Do not treat 440–590 MPa tensile as permission to stamp SA516 Gr.70, SA612 steel plate or SA737 Gr.B.
Impact is the reason buyers pick DIN 17102 instead of DIN 17100. StE315 is the basic quality. If the drawing names −20 °C or −50 °C, the order may actually need TStE315 or EStE315. Write the test temperature, orientation and energy on the purchase order.
How StE / WStE / TStE / EStE Differ at 315
| Grade | Quality idea | Notes |
|---|---|---|
| StE315 | Basic / room-temperature fine grain | This page |
| WStE315 | Elevated temperature (Warm) | Same yield idea, warm service |
| TStE315 | Low temperature (Tief) | Same yield idea, colder impact |
| EStE315 | Special low temperature | Tightest C / P / S in the 315 family |
Same 315 MPa yield idea. Different impact and, on T/E, tighter residuals. SHH STEEL will not ship StE315 against a TStE315 impact temperature without a written change.
Material Comparison
Material Comparison

SA203 Gr.A, SA285 Gr.C and SA299 Gr.A are vessel plates. None of them is StE315.
Fine-Grain Structural Service at 315 MPa
DIN 17102 StE315 / StE 315 is selected when the drawing wants fine-grain, weldable, normalized plate at the intermediate 315 MPa step: frames, tanks, machinery and other work still calculated to the old German book. It is not a free substitute for StE355. It is not automatically a Section VIII plate. If the vessel is ASME, the drawing should name an ASME or ASTM grade such as SA516 Gr.70, SA537 Cl.1 or SA662 Gr.B.
SHH STEEL supplies this plate to fabricators in the United States, Europe, the Middle East and Southeast Asia. It is not nickel low-temp plate like SA203 Gr.D or SA203 Gr.E. It is not QT Ni-Cr-Mo like SA543 Type B Cl.1. It is not Cr-Mo like SA387 Gr.22 Cl.2. Stainless inquiries belong on ASME SA240 or ASTM A240.
Weldability
StE315 is killed fine-grain C-Mn steel. Welding is production welding, and Code welding when the equipment is a vessel.
Qualify procedures to the applicable code. For ASME work that happens to use a dual-named plate, use ASME Section IX. Consumables should match the 440–590 MPa tensile band, not a SA387 Gr.12 Cl.2 Cr-Mo procedure and not a QT procedure from SA517 Gr.F. Preheat follows thickness and hydrogen control. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.
Heat Treatment and Delivery Condition
Usual delivery from SHH STEEL is normalized DIN 17102 StE315 / StE 315 plate. Fine-grain practice and normalize are the product idea. As-rolled shipment is a special agreement.
If the vessel or structure will see PWHT, test coupons shall follow a simulated cycle when the order names it. This is not the QT route used on SA738 Gr.A or SA737 Gr.C. Special heat treatment, extra simulation or third-party hold points add time. Plan about two months when those extras are on the order.
The certificate lists DIN 17102 StE315 (and StE 315 if requested); heat number; heat analysis; product analysis when ordered; tensile results to the correct thickness column; normalize statement; impact when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2. Dual marking to an EN name is available only when chemistry, tensile and impact all fit that EN edition. Do not assume P355N dual marking; that name sits on StE355.
Dimensions
Usual supply range from SHH STEEL for StE315 fine grain steel:
- Thickness: commonly 6 mm – 150 mm. Confirm any request above 150 mm against mill capability
- Width: 1500 mm – 4000 mm
- Length: 3000 mm – 12000 mm
- Cut-to-length plates and nest sizes inside those limits
Ship plate inquiries belong on shipbuilding steel plates or BV Rules. Weathering plate belongs on EN 10025-5 or Corten A/B. TMCP fine-grain structural belongs on EN 10025-4. QT structural belongs on EN 10025-6. Ordinary structural belongs on EN 10025-2 or JIS G3106.
Tolerances
Dimensional limits follow the mill rolling standard named on the order, commonly EN 10029 for plate when the buyer is in Europe. Do not apply ASTM A36/A36M structural tolerances to a DIN fine-grain plate without writing them. UT to EN 10160 or ASTM A435 / A577 / A578 is added when the order names it.
Supplementary Requirements
Most export DIN 17102 StE315 / StE 315 orders add extras. SHH STEEL does not assume them.
Charpy details. Temperature, energy, location and orientation. If the temperature is −40 °C or −50 °C, confirm whether the grade should be TStE315 or EStE315.
Simulated PWHT. When the equipment will be stress-relieved.
NDE. UT per the named method.
Z-direction / through-thickness testing. When the drawing names Z15 / Z25 / Z35.
Third-party. EN 10204 3.2, with inspectors arranged for US, European or Middle East documentation packages.
