Cored Wire Export Prices On October 27, 2026

This page records the cored wire export price for calcium-bearing grades on October 27, 2026, FOB Tianjin Port and in US dollars per tonne. Three lines are quoted: two calcium-silicon cored wires at 13 mm diameter, and a pure calcium cored wire at 9 mm with a stated core weight. Every line is unchanged from the previous session.

Table 1 - Cored wire export prices, October 27, 2026

Basis: FOB Tianjin Port, USD per tonne of wire, for the diameters and core weights shown. Figures are the ranges published for the October 27, 2026 session, compared with the previous session on a like-for-like basis, with no change to specification, diameter or price basis.

Note: all prices held steady vs the previous session.

Each line is a range rather than a single figure, because a quotation is written as a spread across the sellers active in that grade on the day. All three sit on the same basis, so the ordering between grades reads directly from the table. Core weight is completed only for the 9 mm line; for the two 13 mm lines the sheet gives diameter and alloy designation but no core weight, which must come from the seller's specification.

All three cored wire price lines held steady. The low and high ends of every quoted range are identical to those published in the previous session, for the same product, the same diameter and, where quoted, the same core weight.

It is worth being precise about what that says and does not say. It says the published range did not move between the two sessions. It does not say the ends converged or widened, nor that every transaction settled at the same price, since a range is a spread of offers rather than a record of business done. Nor is it a statement about the next session: a flat quotation on October 27 implies nothing about October 28. No cause for the flat result is published here, so none should be inferred.

The practical reading is narrow but useful. The grade-to-grade relationship in Table 1 is unchanged, so a programme costed on the previous quotation still holds its internal ratios, and a choice between the two families need not be revisited on price grounds alone. Quantity, packing, shipment window and the point inside the range at which a seller will work belong to the enquiry.

Cored wire is a delivery format rather than a class of material. A thin strip of low-carbon steel is formed into a tube, filled with an alloy or a pure metal in powder form, and closed into a coiled wire. At the plant it is fed through a wire feeder and guide tube into the ladle, where the sheath melts and releases the filler below the surface. That is why the format exists: it puts a reactive element where it can act on the melt instead of burning at the surface, and the addition rate is set by the length of wire fed.

The diameter marked ∮ is the outside diameter of the finished wire: 13 mm for both calcium-silicon lines, 9 mm for the pure calcium line. Diameter sets which feeder and guide tube geometry the coil runs through, and together with core weight it fixes how much active element arrives per metre consumed. A plant already running one diameter should still confirm feeder and guide tube size against the quoted diameter.

The core weight is given for the pure calcium line only, as Ca 58-68 g/m: how much calcium each metre of wire carries, as a band rather than a single value. Two coils both sold as Ca 98% min at 9 mm need not therefore deliver the same calcium per metre, so the length needed for a given addition differs across the band. This is settled by the mill certificate, not by the quotation.

The two calcium-silicon designations follow the usual convention, with the first number the nominal calcium content and the second the nominal silicon content, iron making up most of the balance. Ca30Si60 therefore describes a higher-calcium, higher-silicon material than Ca28Si55. Both deliver silicon to the heat with the calcium, an advantage where silicon is wanted but a constraint wherever silicon in the heat is tightly capped.

The pure calcium line, Ca 98% min, is the alternative when silicon cannot be carried: its filler is essentially calcium, so treatment can be made without the silicon a calcium-silicon wire brings. The trade-off shows in two places. The wire is drawn to 9 mm, and its band sits above both calcium-silicon lines - 1570-1650 against 1400-1430 and 1250-1280 USD per tonne. That ordering is price per tonne of wire, not per unit of calcium delivered.

Table 2 - The two cored wire families quoted on October 27, 2026

The comparison uses only the specifications and price lines on this sheet. The price row describes wire price per tonne for this session; it is not a cost-per-unit-of-calcium comparison and does not account for differences in feed rate or yield at the plant.

The sheet fixes grade, diameter and, where stated, core weight, plus a price range on an FOB Tianjin Port basis. Everything else that decides whether a shipment works at the plant has to be confirmed separately.

1. Diameter against feed equipment. Confirm that 13 mm or 9 mm matches the guide tube and feeder installed; a mismatch stops the coil from being used.
2. Core weight, where it matters. The 9 mm line is quoted as Ca 58-68 g/m; ask for the core weight of the specific lot. For the two 13 mm lines it must come from the seller's product specification.
3. Basis of the designation. Confirm what Ca30Si60, Ca28Si55 and Ca 98% min mean on the certificate of analysis, with the analytical basis and tolerance on each element.
4. The price base, in full. These figures are FOB Tianjin Port, USD, per tonne of wire. Any other basis, currency or unit needs a separate quotation.
5. Where inside the range the order will be priced. A published range is a spread, not an offer at the midpoint. Confirm the figure applying to the quantity, diameter and delivery window ordered.
6. Packing and protection. Coil mass, dimensions, palletisation, strapping and moisture protection should be agreed in writing; a hygroscopic filler makes packing a quality issue.
7. Quantity, window and validity. Confirm the tonnage tolerance, the loading period and the documents travelling with the shipment. A steady quotation dated October 27, 2026 describes that session and is not a standing offer.

• Three cored wire lines are quoted for October 27, 2026, all FOB Tianjin Port in USD per tonne.
• Ca30Si60 at ∮13 mm is 1400-1430, Ca28Si55 at ∮13 mm is 1250-1280, and Ca 98% min at ∮9 mm with Ca 58-68 g/m is 1570-1650.
• Every line held steady against the previous session, with no movement at either end of any range.
• The calcium-silicon lines sit in a lower price band, but they also deliver silicon, making the choice a chemistry decision as much as a cost one.
• The 9 mm line is the only one here with a published core weight, and that weight is a band, not a single figure.
• Diameter, core weight, packing and validity sit outside the price line and need written confirmation before ordering.
• Before ordering, confirm diameter, core weight and price basis with the cored wire supplier behind the offer, because two wire families share one delivery format.

If your requirement is defined by diameter and core weight rather than by grade name alone, send the diameter, the core weight and the tonnage you plan to draw down, and the quotation can be matched to those parameters instead of to the sheet as a whole.
