Welcome to Hemaokang Steel (Shandong) Co., Ltd. – your reliable partner for premium stainless steel coils. Since our establishment in 2025, we have rapidly grown into a trusted supplier with an annual export value of US$50 million to US$100 million. Our 409 stainless steel coil, specifically engineered for automotive exhaust systems, combines exceptional heat resistance with durability. With a thickness of 1.5mm and rigorous quality control under ISO9001 certification, this product is designed to meet the demanding requirements of exhaust manifolds, mufflers, and catalytic converter components. Whether you are an OEM manufacturer or a distributor, this coil offers consistent performance and cost efficiency.
Product Overview
Our 409 stainless steel coil is a ferritic stainless steel grade that provides excellent resistance to oxidation and corrosion at high temperatures. The 1.5mm thickness ensures structural integrity while maintaining formability for complex exhaust shapes. It is widely used in automotive exhaust systems where heat cycling and corrosive exhaust gases are prevalent.
Key Features & Benefits
- Heat Resistance: Operates reliably in continuous temperatures up to 800°C, with peak excursions up to 900°C, making it ideal for exhaust system components.
- Corrosion Resistance: Resists exhaust gas condensate and road salt, extending service life compared to carbon steel alternatives.
- Formability & Weldability: Excellent ductility allows for deep drawing and bending; readily weldable using standard TIG/MIG techniques.
- Cost-Efficient: Lower nickel content than 304 or 316 grades, providing a balanced solution for exhaust applications without sacrificing performance.
- Consistent Quality: Produced under ISO9001-certified processes, ensuring uniform thickness, surface finish, and mechanical properties across all coils.

Frequently Asked Questions
-
What is the maximum operating temperature of 409 stainless steel coil?
It can be used continuously up to 800°C (1472°F) and intermittently up to 900°C (1652°F) in exhaust applications. -
Can this coil be welded easily?
Yes, 409 stainless steel has good weldability. It can be welded using standard TIG or MIG processes with appropriate filler metal (e.g., 409Nb or 430). -
What standard widths are available besides 1219mm?
We offer custom widths from 600mm to 1500mm. Please specify your required width when ordering. -
How is the coil packaged for export?
Each coil is wrapped with moisture-proof paper, plastic film, and steel strapping, then packed in wooden crates or steel frames for safe sea freight. -
What is the typical lead time?
Standard lead time is 15–25 days after deposit, depending on order quantity and width requirements. -
Does this coil have good resistance to road salt corrosion?
409 stainless steel offers better corrosion resistance than carbon steel, but it is not as resistant as 304. In moderate salt environments, it performs well with proper surface treatment. -
Can you provide a mill test certificate?
Yes, a mill test certificate (MTC) conforming to EN 10204 3.1 is provided with each shipment upon request. -
Is the price FOB Qingdao or CIF?
We offer both FOB Qingdao and CIF terms. Our annual export volume allows us to secure competitive freight rates.
