Frequently Asked Questions
- What makes 904L stainless steel suitable for chemical processing? Its high nickel (23–28%), chromium (19–23%), and molybdenum (4–5%) content provides outstanding resistance to strong acids, chlorides, and stress corrosion cracking, making it ideal for aggressive environments.
- Can you supply coils with thicknesses outside 3.0–12.0mm? Yes, we can customize thicknesses within a range of 2.0mm to 20.0mm upon request. Please contact us for specific requirements.
- What is the standard coil inner diameter? Typical inner diameter is 508mm or 610mm, but we can adjust to match your uncoiling equipment.
- Do you provide samples for testing? Yes, we offer small sample coils (e.g., 1 meter width) for qualification. Sample shipping cost is negotiable.
- How do you ensure the surface quality of hot rolled coils? After hot rolling, coils are pickled and annealed to remove scale and oxide, resulting in a clean, uniform surface suitable for further processing.
- What is the minimum order quantity (MOQ)? Standard MOQ is 5 tons per size. For smaller quantities, please discuss with our sales team.
- Are your coils certified for international standards? Our production is ISO9001 certified. We can also provide material test reports (MTR) per ASTM B625 or EN 10204 upon request.
- What packaging options are available for export? Coils are packed in seaworthy wooden crates, wrapped with waterproof paper, or with steel strips and protective film as per your request.
