DIN 17102 TStE285 Steel Plate | TStE285 Fine Grain Steel supplier

DIN 17102 TStE285, also written TStE 285, TSTE285, DIN17102 TStE285 and TStE285 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 285 MPa. Tensile on thinner product is still typically 390–510 MPa. This is the DIN 17102 low-temperature line that conversion tables map to P275NL1 (EN 10028-3) and S275NL (EN 10025-3). It is not TStE255 and not TStE355. 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 “275 NL fine grain” is incomplete if the drawing still names DIN. Write DIN 17102 TStE285 and the impact temperature. Do not ship StE285 or WStE285 against a TStE285 drawing because those letters are not Tief. Do not ship TStE255 or TStE355 because the yield step is wrong.

DIN 17102 is a legacy specification. New European structural work usually names S275NL under EN 10025-3. New pressure work usually names P275NL1. Replacement projects still name TStE285 when an old German calculation or mill qualification stays on DIN.

This page is not DIN 17100 St44-3. It is not SA516 Gr.60 and 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 TStE285 / TStE 285 tightens phosphorus and sulfur versus StE285 / WStE285.

Heat Analysis — DIN 17102 TStE285 (typical cast / ladle limits)

StE285 / WStE285 use P 0.035 and S 0.030. EStE285 is tighter still. Do not ship a StE285 heat as TStE285. TStE255 manganese is 0.50–1.30. TStE355 manganese is 0.90–1.65. If the order dual-names P275NL1 or S275NL, residuals must also fit the named EN edition. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Room-temperature yield and tensile follow the 285 family. Low-temperature impact is why the T letter exists.

Room-temperature properties — DIN 17102 TStE285 (typical published idea)

Confirm the ordered thickness against the named edition. Do not treat 390–510 MPa tensile as permission to stamp SA516 Gr.60, SA285 Gr.B or SA662 Gr.A.

Impact for TStE285 is the low-temperature package. S275NL comparison is commonly −50 °C. P275NL1 comparison is commonly −40 °C. Write the test temperature, orientation and energy on the order. If the drawing names a still colder package, the grade may be EStE285 / P275NL2, not TStE285.

Same 285 MPa yield idea. Different impact package and, on T/E, tighter residuals. SHH STEEL will not ship TStE285 against an EStE285 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 TStE285.

DIN 17102 TStE285 / TStE 285 is selected for welded structures and pressure equipment that need fine-grain toughness at low temperature at the 285 MPa yield step: tanks, bridges, cold-climate steelwork and other work still calculated to the old German book. It is the practical DIN counterpart to S275NL / P275NL1. 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. TStE285 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.

TStE285 is killed fine-grain C-Mn steel with tighter P / S than StE285. 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 390–510 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 TStE285 / TStE 285 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 TStE285 (and TStE 285 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 S275NL or P275NL1 is available only when chemistry, tensile and impact all fit the named EN edition.

Usual supply range from SHH STEEL for TStE285 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 TStE285 / TStE 285 orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. This is the reason TStE285 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 TStE285.

Stainless inquiries belong on stainless steel products, JIS G4305 or AISI stainless. Other vessel comparisons: SA203 Gr.B, SA302 Gr.B, A516 Grade 60, SA533 Type C Cl.2, SA517 Gr.P.
