Product Details

SS 304 coil specifications are usually defined by four purchasing dimensions: thickness, width, surface finish, and coil weight. For buyers, the most useful approach is to build a specification matrix before requesting a quotation. This makes it easier to distinguish standard production sizes, slit widths, and special-order dimensions.

Ordering tip: A complete coil inquiry should state grade, thickness, width, surface, edge condition, coil weight, standard, tolerance, and required documents. “304 coil” alone is not enough for an accurate technical quotation.

SS 304 Coil Specification Matrix

Thickness	Typical Widths	Common Surface	Typical Supply Status
0.3 mm	600–1524 mm	2B / BA	Standard or special order
0.4 mm	600–1524 mm	2B / BA	Standard or special order
0.5 mm	600–1524 mm	2B / BA	Common
0.6 mm	600–1524 mm	2B / BA	Common
0.8 mm	600–1524 mm	2B / BA	Common
1.0 mm	600–1524 mm	2B / BA	High-demand size
1.2 mm	600–1524 mm	2B / BA	Common
1.5 mm	600–1524 mm	2B / BA	Common
2.0 mm	600–1524 mm	2B / No.1	Common
2.5 mm	600–1524 mm	2B / No.1	Common or special order
3.0 mm	600–1524 mm	2B / No.1	Common or special order

The table represents a practical purchasing range rather than a guarantee of physical inventory. Actual stock availability changes by production schedule, width, surface, and order quantity.

Thickness Options: From 0.3 mm to 3.0 mm

Thin gauge material is commonly selected for appliances, architectural components, kitchen equipment, fabrication, and decorative applications. As thickness increases, the coil becomes more suitable for structural fabrication, equipment components, and applications requiring greater rigidity.

Gauge Range	Typical Sizes	Procurement Consideration
0.3–0.6 mm	0.3 / 0.4 / 0.5 / 0.6 mm	Thickness tolerance and surface quality are especially important.
0.8–1.5 mm	0.8 / 1.0 / 1.2 / 1.5 mm	Broadest range of fabrication applications.
2.0–3.0 mm	2.0 / 2.5 / 3.0 mm	Flatness, edge condition, and coil weight become more important.

Width Matrix: 600, 1000, 1219, 1250, 1500 and 1524 mm

Width is one of the most important factors when selecting a coil. Standard mill widths can reduce processing requirements, while slit widths can be produced for downstream fabrication.

Width	Typical Use	Supply Approach
600 mm	Narrow fabrication and strip processing	Slit or narrow-width supply
1000 mm	General fabrication	Common production option
1219 mm	Imperial-size fabrication and sheet conversion	Frequently requested
1250 mm	Metric sheet conversion	Common
1500 mm	Wide sheet and fabrication applications	Common mill-width option
1524 mm	Wide-format applications	Availability depends on mill and specification

Surface Finish: 2B, BA, No.1 and 2D

2B is one of the most widely specified cold-rolled surfaces. It provides a smooth, relatively reflective finish suitable for many industrial and fabrication applications.

BA is produced through bright annealing and provides a brighter appearance. It is often selected where surface appearance is important.

No.1 is generally associated with hot-rolled, annealed and pickled material. It is more commonly selected for heavier gauges and industrial applications.

2D is a cold-rolled, annealed and pickled surface with a duller appearance than 2B.

Important: Surface designation should be confirmed against the applicable ASTM, EN, JIS, or project specification. Similar commercial descriptions do not always mean identical surface requirements.

Coil Weight: Standard Coils vs Small Trial Coils

For many industrial orders, a coil weight of approximately 5–15 metric tons is practical. Smaller coils of approximately 1–3 metric tons may be useful for trial orders, small fabrication projects, or customers that have limited decoiling capacity.

Actual coil weight should be confirmed before ordering because the permissible range depends on the production line, outer diameter, inner diameter, width, thickness, lifting equipment, and transportation requirements.

Mill Edge vs Slit Edge

Edge Type	Meaning	Typical Requirement
Mill Edge (ML)	Original rolled edge	Useful when the customer will cut or process the edge later.
Slit Edge (SL)	Edge produced by longitudinal slitting	Suitable when a precise narrow width is required.

Thickness Tolerance and Standards

Thickness tolerance should be specified according to the applicable product standard rather than using a universal number. ASTM and EN standards can contain different tolerance systems based on nominal thickness, width, product form, and manufacturing condition.

For a technical RFQ, specify the applicable standard together with the nominal thickness. If a project requires tighter-than-standard tolerance, state the target range separately so the supplier can confirm manufacturing feasibility before production.

1219 × 1.0 mm × 2B: A Practical High-Demand Combination

A 1219 mm × 1.0 mm × 2B configuration is a practical combination for customers requiring a commonly processed width, medium-thin gauge, and standard cold-rolled surface. It can be converted into sheets or slit into narrower widths according to downstream requirements.

However, “popular” does not automatically mean “in stock.” Availability should always be confirmed against the current warehouse and production schedule.

How to Build a Complete 304 Coil RFQ

Grade: 304 with the required standard designation.
Thickness: nominal thickness plus tolerance requirement.
Width: exact width and width tolerance.
Surface: 2B, BA, No.1, 2D, or another specified finish.
Edge: ML or SL.
Coil weight: standard or small-coil requirement.
Quantity: total tonnage and number of coils if required.
Documents: MTR, inspection certificate, and other project documents.

Example RFQ:

304 stainless coil, 1.0 × 1219 mm, 2B finish, slit edge, 5–15 MT coils, applicable ASTM specification, MTR required.

FAQ

What is the common thickness range for 304 stainless coil?

Cold-rolled products are commonly ordered across a wide range of gauges. The 0.3–3.0 mm range covers many fabrication requirements, but other thicknesses can also be produced or supplied depending on the applicable product form and specification.

What is the most common surface for 304 coil?

2B is one of the most widely used cold-rolled surfaces. BA is selected when a brighter appearance is required, while No.1 is more common for heavier hot-rolled material.

What is the difference between mill edge and slit edge?

Mill edge is the original rolled edge, while slit edge is created by longitudinal cutting. Slit edge is commonly selected when an exact narrow width is required.

Can 304 coil be supplied in 1219 mm width?

Yes. 1219 mm is a commonly requested width for applications using imperial-size sheet dimensions, although actual availability depends on thickness, finish, coil weight, and production schedule.

Should coil weight be included in an RFQ?

Yes. Coil weight affects handling, decoiling, transportation, and production planning. Stating the preferred weight range helps the supplier provide a more precise quotation and supply proposal.
