DIN 17102 TStE355 Steel Plate | TStE355 Fine Grain Steel supplier

DIN 17102 TStE355, also written TStE 355, TSTE355, DIN17102 TStE355 and TStE355 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 355 MPa. Tensile at ≤70 mm is still 490–630 MPa. What changes versus StE355 and WStE355 is the toughness package and a tighter chemistry. The usual modern comparisons are P355NL1 (EN 10028-3, material no. 1.0566) and S355NL (EN 10025-3). 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 “355 fine grain” is incomplete. Write DIN 17102 TStE355 and the impact temperature. Do not ship StE355 or WStE355 against a TStE355 drawing because all three look like 355 MPa plate. TStE355 exists because the buyer needs guaranteed notch toughness at low temperature, not only room-temperature tensile.

DIN 17102 is a legacy specification. New European structural work usually names S355NL under EN 10025-3. New pressure work usually names P355NL1. Replacement projects still name TStE355 when an old German calculation or mill qualification stays on DIN.

This page is not DIN 17100 St52-3. It is not SA516 Gr.70. Grade 70 is ASME carbon vessel plate at 260 MPa yield. TStE355 is 355 MPa yield fine-grain plate with a low-temperature designation. It is not nickel plate like SA203 Gr.D. 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, not as automatic substitutes.

DIN 17102 TStE355 / TStE 355 tightens carbon, phosphorus and sulfur versus StE355 / WStE355.

Heat Analysis — DIN 17102 TStE355 (typical cast / ladle limits)

StE355 / WStE355 carbon heat is 0.20% max, P 0.035, S 0.030. EStE355 is tighter still. Do not ship a StE355 heat as TStE355. If the order dual-names P355NL1 or S355NL, residuals and P/S must also fit the named EN edition. 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 further, write that on the order.

Room-temperature yield and tensile follow the 355 family. Low-temperature impact is why the T letter exists.

Room-temperature tensile and yield — DIN 17102 TStE355 (typical published bands)

Do not quote 355 MPa yield on an 80 mm plate. Do not treat 490–630 MPa tensile as permission to stamp SA516 Gr.70 or SA662 Gr.C.

Impact for TStE355 is the low-temperature package. S355NL comparison is commonly −50 °C. P355NL1 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 EStE355 / P355NL2, not TStE355.

Same 355 MPa yield idea. Different impact package and, on T/E, tighter C / P / S. SHH STEEL will not ship TStE355 against an EStE355 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 TStE355.

DIN 17102 TStE355 / TStE 355 is selected for welded structures and pressure equipment that need fine-grain toughness at low temperature: tanks, bridges, offshore-related steelwork, process equipment and other work still calculated to the old German book. 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.A 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 for toughness. TStE355 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.

TStE355 is killed fine-grain C-Mn steel with tighter C / P / S than StE355. 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 490–630 MPa tensile fine-grain practice, 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 TStE355 / TStE 355 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 TStE355 (and TStE 355 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 available only when chemistry, tensile and impact all fit the named EN edition.

Usual supply range from SHH STEEL for TStE355 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 TStE355 / TStE 355 orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. This is the reason TStE355 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 TStE355.

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.
