DIMENSIONS & DELIVERY
321 Coil supply range
Choose the production route that matches your order. The quotation confirms the grade, thickness, width, surface and delivery combination.
Coil inside diameter, coil weight, winding and packing to be agreed for your production line
Mill surface
2B / 2D / BA / 2R / BA0 / BA1 / BA2
Sheye surface processing
No.4 / HL / No.3 / SB / 6K / 8K; special finishes by agreement
Specification routes
GB/T 3280 · ASTM / ASME (specification to be agreed) · JIS G4305 · EN 10088 / EN 10028 (applicable part to be agreed) · Q/TB 3084 · IS 6911:2017
State the exact standard number, applicable part, edition and grade in your enquiry. The quotation and mill test certificate identify the agreed specification; a reference list does not certify every combination.
For cold-rolled widths above 1524 mm, discuss the TISCO mill route, grade and available thickness with Sheye.
BA0, BA1 and BA2 are mill finish descriptions. Confirm the mill code and an agreed surface sample; they are not universal equivalents.

Mill surface codes and decorative finish names are confirmed against the agreed description or sample. Additional processing depends on the grade, thickness and required finish.
PRODUCT DETAILS
Specify 321 Stainless Steel Coil for your process
Select the supplied form
Sheye Metal offers 321 stainless steel coil through cold-rolled and hot-rolled routes. State which form is required and reference the complete material standard used in your purchasing specification. Where a drawing or approved material list names 321, include that requirement so the quotation and material documentation can be checked against it.
Describe the next operation
Explain whether the coil will be slit, cut into sheets, formed or prepared for another fabrication step. Cold-rolled mill finishes and hot-rolled NO.1 or 1D material have separate surface specifications. Identify any additional finish or protective treatment needed before shipment, including the appearance required on each side of the material.
Confirm the coil configuration
Provide thickness, width and quantity together with inside diameter, coil weight limits and winding requirements. Define dimensional tolerances and inspection documentation as part of the same inquiry. Each requested combination should be confirmed before purchase, including any processing sequence, identification or packaging requirements that affect handling at your facility.
PRACTICAL BUYING QUESTIONS
Buying 321 Coil for Processing
Which starting condition should be defined for 321 coil?
Identify the cold-rolled or hot-rolled supply route and the required delivery condition under the agreed specification. If the application needs a separate stabilizing treatment, make that explicit rather than assuming every annealed coil has received it. The enquiry should connect the starting material with the planned slitting, forming or welding sequence and with the required documentation. The titanium analysis alone does not describe the complete metallurgical condition.
What should remain traceable after a 321 coil is slit or cut?
The parent heat and coil identity should remain linked to the resulting material and its certificate. Review the stabilizer rule required by the specified standard, along with the other analysis and mechanical results. Slit width, edge requirements, coil-handling limits and protection belong to the processing order. A trade name or titanium result taken out of context cannot replace the full material acceptance basis for the parts made from that coil.
