DIN 17102 EStE380 Steel Plate | EStE380 Fine Grain Steel

DIN 17102 EStE380, also written EStE 380, ESTE380, DIN17102 EStE380 and EStE380 steel plate, is a weldable normalized fine-grain structural steel under DIN 17102. The E prefix is the special low-temperature quality — colder and cleaner than TStE380. Yield in the thin band is still 380 MPa. Tensile at ≤70 mm is still typically 510–650 MPa. This grade sits above EStE355 and below EStE420. Modern EN books jump from P355NL2 to P420NL2. EStE380 is the old German special-low-temp step that stayed between those two. 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 “380 fine grain special low temp” is incomplete. Write DIN 17102 EStE380 and the impact temperature. Do not ship StE380, WStE380 or TStE380 against an EStE380 drawing. Do not ship EStE355 or EStE420 because the yield step is wrong.

DIN 17102 is a legacy specification. New European pressure work usually picks P355NL2 or P420NL2. There is no equally clean single EN name for EStE380. Replacement projects still name EStE380 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 or 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 and ASME SA662, not as automatic substitutes.

DIN 17102 EStE380 / EStE 380 is the cleanest 380 column in this book. Product analysis is slightly wider than heat analysis.

Heat Analysis and Product Analysis — DIN 17102 EStE380 (typical limits)

Compare the 380 family:

Do not ship a TStE380 heat as EStE380. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Room-temperature yield and tensile follow the 380 family. Special low-temperature impact is why the E letter exists.

Room-temperature properties — DIN 17102 EStE380 (typical published bands)

Do not quote 380 MPa yield on an 80 mm plate. Do not treat 510–650 MPa tensile as permission to stamp SA516 Gr.70, SA662 Gr.A or SA285 Gr.A.

Impact for EStE380 is the special low-temperature package. Write the test temperature, orientation and energy on the order. Do not assume a TStE380 coupon covers EStE380.

Same 380 MPa yield idea. E is not a marketing letter on TStE380. E has lower carbon, lower P and S, and a colder quality idea. SHH STEEL will not ship TStE380 against an EStE380 purchase order without a written change.

SA285 Gr.C, SA299 Gr.B and SA737 Gr.C are also vessel or HSLA plates. None of them is EStE380.

DIN 17102 EStE380 / EStE 380 is selected for welded structures and pressure equipment that need the coldest fine-grain package at the 380 MPa step: low-temperature tanks, cold-climate steelwork and other work still calculated to the old German book. It is not a free substitute for EStE420. 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.B or SA203 Gr.F. Those grades use nickel. EStE380 uses fine grain, low residuals and normalize. It is not QT Ni-Cr-Mo like SA543 Type B Cl.3. It is not Cr-Mo like SA387 Gr.22 Cl.2 or SA387 Gr.11 Cl.2. Stainless inquiries belong on ASME SA240 or ASTM A240.

EStE380 is killed fine-grain C-Mn steel with the lowest C / P / S in the 380 family. 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 510–650 MPa tensile band, not a SA387 Gr.12 Cl.2 Cr-Mo procedure and not a QT procedure from SA517 Gr.Q. 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 EStE380 / EStE 380 plate. Fine-grain practice and normalize are the product idea. As-rolled shipment is a special agreement and is a poor fit for a special 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.B. 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 EStE380 (and EStE 380 if requested); heat number; heat analysis including the tighter C / P / S; 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 P420NL2 is not automatic. That EN name sits closer to EStE420.

Usual supply range from SHH STEEL for EStE380 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 EStE380 / EStE 380 orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. This is the reason EStE380 exists. Write the temperature explicitly.

Product analysis. Add this when the destination file wants finished-plate chemistry, not only ladle chemistry.

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.

Restricted residuals. Some European files copy EN 10028-3 NL2 options onto EStE380. Write those options on the order.

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 is not EStE380.

Stainless inquiries belong on stainless steel products, JIS G4305 or AISI stainless. Other vessel comparisons: SA302 Gr.A, SA204 Gr.B, A516 Grade 70, SA533 Type C Cl.1, SA517 Gr.P, SA738 Gr.C.

Third-party inspection can be arranged before loading for US, European or Middle East projects. Packing is seaworthy, with edge protection and marking in English as specified on the order.

If the buyer actually needs EStE420 / P420NL2, say so on the inquiry. If the buyer needs a PED / 3.2 file, say so on the inquiry. Do not assume a domestic Chinese certificate format will pass at destination.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We supply ASTM / ASME / EN / DIN / JIS steel to the USA, Europe, the Middle East and Southeast Asia. On DIN 17102 EStE380 / EStE 380 that means mill pricing, EStE380 chemistry with tight C / P / S reported as heat analysis and as product analysis when ordered, recorded normalize, tensile results to the correct thickness column, impact at the named special low temperature, 3.1 as standard and 3.2 when specified. Trade terms include FOB Shanghai and CIF Houston / Rotterdam / Jebel Ali.

We keep the prefix and the number on the order. EStE380 is not TStE380. EStE380 is not StE380. EStE380 is not WStE380. EStE380 is not EStE355. EStE380 is not EStE420. DIN 17102 is not DIN 17100. EStE380 is not SA516 Gr.70. EStE380 is not SA387 Gr.22 Cl.2. If the drawing names TStE380, we will not ship EStE380 and call the grades the same just because yield is 380 MPa.
