DIN 17102 TStE315 Steel Plate | TStE315 Fine Grain Steel

DIN 17102 TStE315, also written TStE 315, TSTE315, DIN17102 TStE315 and TStE315 steel plate, is a weldable normalized fine-grain structural steel under DIN 17102. The T prefix means Tief — low-temperature quality. Yield in the thin band is still 315 MPa. Tensile at ≤70 mm is still typically 440–590 MPa. This grade sits between TStE285 and TStE355. It is not the S275NL / P275NL1 line and not the S355NL / P355NL1 line. Buyers still name it when an old German drawing kept the 315 Tief step. 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 low temp” is incomplete. Write DIN 17102 TStE315 and the impact temperature. Do not ship StE315 or WStE315 against a TStE315 drawing. Do not ship TStE285 or TStE355 because the yield step is wrong.

DIN 17102 is a legacy specification. New European work usually picks S275NL / P275NL1 or S355NL / P355NL1 under EN 10025-3. There is no single EN name as clean as TStE285 → P275NL1 or TStE355 → P355NL1. Replacement projects still name TStE315 when the original German file stays on that number.

This page is not DIN 17100 St52-3. It is not SA516 Gr.70. It is not nickel plate like SA203 Gr.A. It is not ASTM A36 steel plate. It is not QT alloy under ASME SA387 or ASME SA543.

Company scope: global steel mill sourcing partner – SHH STEEL.

This plate sits in structural steel plates, high strength low alloy plates and next to pressure vessel steel plates. ASME carbon comparisons belong on ASME SA516 and ASME SA662, not as automatic substitutes.

DIN 17102 TStE315 / TStE 315 tightens phosphorus and sulfur versus StE315 / WStE315.

Heat Analysis — DIN 17102 TStE315 (typical cast / ladle limits)

StE315 / WStE315 use P 0.035 and S 0.030. EStE315 is tighter still. Do not ship a StE315 heat as TStE315. TStE285 manganese is 0.60–1.40. TStE355 manganese is 0.90–1.65. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Room-temperature yield and tensile follow the 315 family. Low-temperature impact is why the T letter exists.

Room-temperature properties — DIN 17102 TStE315 (typical published bands)

Do not quote 315 MPa yield on an 80 mm plate. Do not treat 440–590 MPa tensile as permission to stamp SA516 Gr.70, SA662 Gr.A or SA285 Gr.B.

Impact for TStE315 is the low-temperature package. Write the test temperature, orientation and energy on the order. If the drawing names a still colder package, the grade may be EStE315, not TStE315.

Same 315 MPa yield idea. Different impact package and, on T/E, tighter residuals. SHH STEEL will not ship TStE315 against an EStE315 impact temperature without a written change.

SA285 Gr.C, SA299 Gr.A and SA737 Gr.B are also vessel or HSLA plates. None of them is TStE315.

DIN 17102 TStE315 / TStE 315 is selected for welded structures and pressure equipment that need fine-grain toughness at low temperature at the intermediate 315 MPa step: tanks, cold-climate steelwork and other work still calculated to the old German book. It is not a free substitute for TStE355. It is not automatically an ASME Section VIII plate. If the vessel is ASME, the drawing should name an ASME or ASTM grade such as SA516 Gr.70, SA662 Gr.C or SA537 Cl.1.

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. Those grades use nickel. TStE315 uses fine grain, tighter residuals and normalize. 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.

TStE315 is killed fine-grain C-Mn steel with tighter P / S than StE315. 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.

Usual delivery from SHH STEEL is normalized DIN 17102 TStE315 / TStE 315 plate. Fine-grain practice and normalize are the product idea. As-rolled shipment is a special agreement and is a poor fit for a low-temperature quality.

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.B 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 TStE315 (and TStE 315 if requested); heat number; heat analysis; product analysis when ordered; tensile results to the correct thickness column; normalize statement; impact at the named temperature. Certificates may be EN 10204 3.1 or EN 10204 3.2. Dual marking to S355NL or P355NL1 is not automatic. Those EN names sit on TStE355.

Usual supply range from SHH STEEL for TStE315 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.

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.

Most export DIN 17102 TStE315 / TStE 315 orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. This is the reason TStE315 exists. Write −20 °C, −40 °C or −50 °C explicitly.

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.

These names are project-comparison grades. They are not automatic substitutes.

ASME SA515 and ASTM A285 are not TStE315.

Stainless inquiries belong on stainless steel products, JIS G4305 or AISI stainless. Other vessel comparisons: SA203 Gr.B, SA302 Gr.B, A516 Grade 70, SA533 Type C Cl.2, SA517 Gr.P, SA738 Gr.C.
