Welcome to Hemaokang Steel (Shandong) Co., Ltd., a trusted supplier of high-quality stainless steel products. Our Stainless Steel Coil 409/410/420 Grade in cold-rolled strip form is specifically engineered for the demanding requirements of heat exchanger manufacturing. With a thickness range of 0.5mm to 2.5mm, this product offers exceptional dimensional accuracy, consistent mechanical properties, and excellent surface finish. As a company with an annual export value of US$50–100 million and ISO9001 certification, we are committed to delivering reliable performance and global standards.

Product Features and Technical Specifications

Versatile Grades: The coil is available in three popular stainless steel grades: 409 (ferritic, excellent heat resistance and oxidation resistance), 410 (martensitic, high strength and moderate corrosion resistance), and 420 (martensitic, high hardness and good wear resistance). Each grade is tailored to different heat exchanger applications.
Precise Thickness Control: From 0.5mm to 2.5mm, with tight tolerances (±0.05mm) to ensure uniform heat transfer and easy fabrication.
Cold Rolled Surface: Smooth, bright annealed finish that reduces friction and improves cleaning efficiency in heat exchanger assemblies.
Customizable Width: Standard widths range from 200mm to 1250mm, with custom widths available upon request to match your specific coil requirements.
Excellent Formability: The cold rolling process enhances ductility and allows for bending, stamping, and welding without cracking.

Why Choose Our Stainless Steel Coil for Heat Exchanger Manufacturing?

Optimized Thermal Performance: The cold-rolled strip offers uniform thickness, which ensures consistent heat transfer efficiency across the entire coil, reducing energy loss in your heat exchanger systems.
Corrosion Resistance: Grade 409 provides good resistance to exhaust gases and mild corrosive environments; Grade 410 and 420 offer enhanced durability in high-temperature and abrasive conditions, extending the service life of heat exchangers.
Cost-Effective Solution: By selecting the appropriate grade, you can balance performance and material cost. For example, Grade 409 is an economical choice for exhaust gas heat exchangers, while Grade 420 suits high-wear applications.
Easy Fabrication: The material is supplied in coils with consistent edge quality and flatness, allowing for efficient slitting, cutting, and forming. This reduces production downtime and scrap rates.
Global Compliance: Our coils are manufactured in accordance with international standards such as ASTM A240 and JIS G4304, with ISO9001 quality management system certification. We also offer third-party inspection services upon request.

Frequently Asked Questions (FAQ)

Q: What is the minimum order quantity (MOQ) for this stainless steel coil?
A: Our standard MOQ is 5 tons per grade and thickness. For smaller quantities, please contact us to discuss possible options.
Q: Can you supply coils with custom widths other than the standard range?
A: Yes, we offer custom slitting services. Widths from 50mm to 1250mm are available upon request, subject to mill capabilities.
Q: What is the typical lead time for delivery?
A: For standard specifications, delivery is usually 15–25 working days after order confirmation. Custom orders may take 25–35 days depending on complexity.
Q: Are these coils suitable for manufacturing plate heat exchangers or shell-and-tube heat exchangers?
A: Yes, our cold-rolled strips are widely used in various heat exchanger types, including plate, gasketed, and welded heat exchangers, thanks to their excellent formability and dimensional accuracy.
Q: How do you ensure the quality of the material?
A: We have a strict quality control system compliant with ISO9001. Each coil undergoes chemical composition analysis, mechanical testing, and surface inspection. Mill test certificates are provided with each shipment.
Q: What packaging do you use for export?
A: Coils are packed with anti-rust paper, plastic film, and steel strapping, then loaded in containers or break-bulk vessels. Additional wooden crates or pallets can be arranged if required.
Q: Can I get samples before placing a bulk order?
A: Yes, we provide free samples (up to 1 kg) for quality evaluation. The buyer pays for shipping costs, which can be refunded upon order placement.
Q: What is the difference between grade 409, 410, and 420 for heat exchanger applications?
A: Grade 409 is ideal for low-temperature exhaust gas heat exchangers due to its high thermal conductivity and good oxidation resistance. Grade 410 offers higher strength and is suitable for high-pressure systems. Grade 420 provides maximum hardness and wear resistance, often used in heat exchangers exposed to abrasive particles or high-velocity fluids.
