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.

PRODUCT DETAILS
Specify 304L Stainless Steel Coil for your process
For a project calling for 304L, keep that grade requirement explicit throughout the quotation and material documentation. Include any welding, forming or other downstream requirements for review.
Define the coil as it will enter your production line: thickness, width, inside diameter, coil weight and winding requirements. Slitting and protection are reviewed as part of the same specification.
Project requirements
Identify the 304L specification and any process or documentation conditions that apply to the finished component.
Prepare the coil for your next process
Include finished slit width, edge and burr requirements, acceptable joints where relevant, and the way the coil will be fed and unwound. Published slitting capabilities are checked against the material and individual order.
PRACTICAL BUYING QUESTIONS
304L coil: downstream fabrication questions
Why choose 304L coil for a downstream welded product?
Low carbon reduces the tendency toward sensitization as the material passes through welding or later thermal cycles. This can be useful when a formed component will be welded and the completed assembly cannot receive a full solution anneal. Explain the forming sequence and welding route when requesting coil, alongside the specified condition and surface. 304L does not automatically solve distortion, chloride exposure or demanding forming requirements; those still need to be matched to the finished component.
Can I assume every 304L coil is also certified as 304?
No. Ask for 304/304L certification if the contract needs both and inspect the mill certificate for the delivered material. Actual carbon and strength values may overlap the requirements of the two grades, but compliance includes the complete relevant specification. The certificate and material identification establish what was supplied. Do not infer dual status from a low-carbon analysis alone, and do not assume a higher permitted nickel ceiling means every coil has a particular nickel content.
