Our commitment to ISO9001 standards guarantees consistent performance, making us a reliable partner for global buyers.
Key Features and Technical Specifications:
- Superior Corrosion Resistance: 904L grade contains high molybdenum (4.0-5.0%) and copper (1.0-2.0%), providing excellent resistance to reducing acids and halide pitting.
- Precise Thickness Control: Produced with tolerance of ±0.03mm, ensuring uniform performance in fabrication processes like stamping, bending, and welding.
- Wide Width Options: Available in standard widths of 1000mm, 1219mm, 1250mm, and 1500mm, with custom widths up to 2000mm upon request.
- Complete MTC Included: Each coil comes with a detailed Mill Test Certificate showing chemical composition, mechanical properties, and heat treatment records.
- Versatile Surface Finishes: Choose from 2B (bright annealed), BA (bright annealed), or No.1 (hot rolled) finish to match your application needs.
- Excellent Weldability: Low carbon content (≤0.02%) minimizes carbide precipitation during welding, maintaining corrosion resistance in heat-affected zones.
- ISO9001 Certified Production: Our manufacturing facility is ISO9001:2015 certified, ensuring consistent quality control from raw material sourcing to final packaging.

Frequently Asked Questions (FAQ)
-
Q: What does MTC mean and why is it important for 904L coils?
A: MTC stands for Mill Test Certificate, which documents the chemical composition, mechanical properties, and heat treatment of the coil. For the chemical industry, this certificate is crucial for verifying material compliance with project specifications (e.g., ASTM B625) and ensuring safety in corrosive environments. Every coil from Hemaokang Steel includes an MTC. -
Q: Can the coil be supplied in custom widths and thicknesses outside 0.6-2.0mm?
A: Yes, we offer customization. While the standard thickness range is 0.6-2.0mm, we can produce thinner (down to 0.3mm) or thicker (up to 3.0mm) coils on request. Width can be customized from 600mm to 2000mm depending on the thickness. Please contact our sales team with your specific needs. -
Q: Is this coil suitable for use in sulfuric acid environments?
A: 904L is specifically designed to resist sulfuric acid at moderate concentrations (up to 50% at room temperature) and elevated temperatures. Its high copper content provides excellent protection against reducing acids. However, for concentrated hot sulfuric acid, we recommend consulting our technical team for application-specific advice. -
Q: What is the typical lead time for an order of 904L stainless steel coils?
A: For standard sizes (e.g., 0.6-2.0mm x 1219mm x C), the lead time is typically 15-20 days after deposit. For custom dimensions or special surface finishes, it may extend to 25-30 days. We can arrange faster delivery for urgent orders subject to stock availability. -
Q: How is the coil packaged to prevent damage during sea freight?
A: Our standard packaging includes: inner plastic film wrapping, anti-rust paper, outer steel strapping, and wooden pallets or crates for heavy coils. For fragile or polished surfaces, we add additional protective foam. We also offer custom packaging such as wooden cases or waterproof covers for extra protection in humid climates. -
Q: Does your company accept third-party inspection before shipment?
A: Absolutely. We welcome inspections by SGS, Bureau Veritas, or any third-party agency nominated by the buyer. The inspection can include dimensional checks, surface quality, chemical analysis, and mechanical tests. We coordinate access and provide necessary documentation to facilitate the process. -
Q: What is the minimum order quantity (MOQ) for 904L coils?
A: Our standard MOQ is 1 ton per size. However, we can accept trial orders of 500 kg for new customers to evaluate quality. For larger projects, we offer volume discounts and flexible payment terms including T/T and L/C. -
Q: Can you provide samples for quality testing before bulk order?
A: Yes, we can supply free samples (customer pays shipping) of 300mm x 300mm pieces or coil ends. Sample availability depends on current production. We can also provide material test reports for the sample batch to ensure consistency with bulk production.
