Whether you need consistent performance for deep drawing, welding, or general fabrication, our 304 2B coil delivers the reliability and surface excellence your projects require.
Product Features & Technical Specifications
Our 304 stainless steel coil is cold-rolled to achieve a smooth, bright 2B finish that is both aesthetically pleasing and functional. Below are the key features and benefits:
- Superior Corrosion Resistance: The 304 grade offers excellent resistance to oxidation, acids, and chlorides, making it ideal for kitchen equipment, chemical containers, and architectural trim.
- Excellent Formability & Weldability: Suitable for deep drawing, bending, and stamping without cracking or surface defects. Can be welded using standard techniques (TIG, MIG, spot).
- Precise Dimensional Tolerance: Manufactured with tight thickness and width tolerances (±0.05mm) to ensure consistent processing in automated lines.
- Bright 2B Surface: A cold-rolled, annealed, and pickled finish with a smooth, matte appearance. Ideal for applications where both aesthetics and hygiene are required (e.g., food processing, medical equipment).
- Full Traceability: Each coil comes with a Mill Test Report (MTR) certifying chemical composition and mechanical properties per ASTM A240.
- Customizable Packaging: Standard export seaworthy packing with anti-rust paper, steel bands, and wooden pallets; customizable according to customer requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 304L stainless steel coil?
A: 304L has lower carbon content, which reduces carbide precipitation during welding and provides better intergranular corrosion resistance. Our standard 304 coil is suitable for most applications; if you need 304L for heavy welding, we can supply it upon request. -
Q: Can you provide the Mill Test Report (MTR) before shipment?
A: Yes, a Mill Test Report is issued for each heat/lot and can be sent to you prior to shipment for verification. -
Q: What are the typical lead times for a 20-ton order?
A: Standard lead time is 7–15 days, depending on thickness and width availability. Express production is available for urgent orders with an additional fee. -
Q: How is the coil packaged for export?
A: We use rust-proof paper, plastic film, steel strapping, and either wooden pallets or crates to protect the coil during sea transportation. Custom packaging options are available. -
Q: Do you offer slitting or cut-to-length services?
A: Yes, we can slit coils to narrower widths or cut sheets to specified lengths up to 4 meters. Please inquire for dimensions. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment), L/C at sight, and other negotiable terms for long-term partners. -
Q: Is the 1-year warranty valid for all coating or surface issues?
A: The warranty covers defects in material and workmanship under normal storage and processing conditions. Surface scratches or damages caused by improper handling are not covered. Please refer to our warranty policy for details. -
Q: Can you supply other stainless steel grades like 316 or 201?
A: Yes, our product range includes 201, 304, 316, 316L, 321, 430, and more. Contact us for grade-specific inquiries.
