Mitchell Stainless is a reliable manufacturer and supplier of Stainless Steel 409 Coils based in Hamilton, New Zealand. They provide effective solutions for corrosion resistance and heat performance at a cost-effective price. With state-of-the-art processing facilities and rigorous quality control, Mitchell Stainless ensures that their coils meet international standards and cater to specific customer needs. Stainless Steel 409 is a ferritic grade known for its excellent oxidation resistance and formability, making it a great choice for automotive and industrial uses. With a strong focus on technical expertise, consistent supply, and customer service, Mitchell Stainless is dedicated to supporting both local and global industries with durable, high-performance stainless steel coil products.
Stainless Steel 409 is a chromium-based ferritic stainless steel that contains around 10.5–11.75% chromium and has low carbon content. This unique blend gives it good oxidation resistance and moderate corrosion resistance in mildly aggressive environments. The alloy boasts stable mechanical properties, including decent tensile strength, good ductility, and excellent thermal fatigue resistance. SS 409 coils are easy to weld and form, making them perfect for roll forming and fabrication. Their magnetic properties and resistance to stress corrosion cracking enhance their performance in high-temperature and exhaust-related applications.
