GNEE Steel Ships 194.22 Tons SA516 Gr.70(N) Plates To South Korea

GNEE Steel has completed shipment of 214 plates - 194.22 metric tons - of normalized SA516 Gr.70(N) pressure vessel steel plate to a customer in South Korea in October 2026. The mixed-size order spans 21–38 mm thickness and comes with mill test certificates and SGS verification, produced and shipped within 20 days.

The order covered 16 line items of SA516 Gr.70(N) plate, all produced in normalized condition and shipped in a single consignment:

Before this order was signed, the Korean buyer visited the GNEE Steel facility in person - a routine we encourage for every new pressure-vessel-grade customer:

• Plate warehouse tour: the customer walked through the SA516 Gr.70(N) inventory, checked stenciling, heat numbers and edge condition on plates that later went into their order.
• Production line review: rolling, heat treatment (normalizing furnace), cutting and blasting lines were shown in operation.
• Testing lab inspection: the customer witnessed the tensile testing machine and Charpy V-notch impact test equipment used for A516 release testing.
• Document review: sample MTCs and SGS third-party inspection reports from previous export orders were reviewed on site.

The visit ended with the packing and marking standard for sea-worthy export confirmed face to face - the same standard used for this 194-ton consignment.

SA516 Gr.70(N) is the normalized version of ASME SA-516 / ASTM A516 Grade 70, the most widely specified carbon steel plate for pressure vessels and boilers:

Every plate in this order shipped with a Mill Quality Test Certificate (MTC) listing heat number, ladle chemical analysis, mechanical test results and the heat-treatment condition. For this Korean order the certificates were supported by SGS third-party verification, so the customer's QA team could clear the material into fabrication without re-testing at their own cost.

The consignment was packed to sea-worthy standard: steel-strapped bundles on wooden/steel saddles, seaworthy surface protection, and clear stencil marking (heat number, size, order number) on every plate for fast port-side identification. With 30% prepayment received, production was completed and shipment released within the agreed 15–20 day window, with the balance settled against a copy of the Bill of Lading.

• Match the heat number stenciled/stamped on each plate against the MTC - one-to-one, no gaps.
• Confirm the MTC heat-treatment column states Normalized; "as-rolled" is not Gr.70(N).
• Check tensile results: 485–620 MPa tensile strength, ≥260 MPa yield.
• Verify Charpy V-notch test temperature and absorbed energy against ASTM A20 or your contract line.
• Review dimensional tolerances and surface condition against ASTM A20 / A516 requirements.
• If ultrasonic testing was ordered (e.g. ASTM A435 / SE 0207 level), check the UT report covers 100% of plates.
• For third-party orders, confirm the SGS (or BV/TUV) report number matches the shipment and heat list.

What is the difference between SA516 Gr.70 and SA516 Gr.70N?

Same chemistry family, different delivery condition: Gr.70N is supplied normalized (heated above the transformation range and air-cooled), which refines the grain and improves low-temperature toughness. For thick plates and low design temperatures, most vessel fabricators specify the N condition. Impact testing requirements are then applied per ASTM A20.

What is the price of SA516 Gr.70N steel plate per kg?

A recent export reference: USD 0.70/kg FOB China for a 194-ton, 16-size mixed order shipped to South Korea (October 2026 PI). Actual price moves with plate size mix, quantity, Charpy/UT test requirements and mill capacity - email your size list for a same-week quotation.

What documents come with an SA516 Gr.70N export order?

Standard set: Mill Quality Test Certificate (MTC), commercial invoice, packing list, Bill of Lading, and certificate of origin. SGS or other third-party inspection reports are provided when ordered. For shipments to South Korea, China–Korea FTA preferential certificate of origin documentation can be arranged to reduce import duty - confirm at booking.
