Nial Sheets and Plates, Houston, USA, is a reliable manufacturer and exporter of quality metal products, including Stainless Steel 409 Coils and Slitting Coils. Renowned for their superior corrosion and heat resistance, these coils are especially desirable for use in automotive exhaust applications, industrial machinery, and building construction. Nial commits to precision manufacturing, reliability, and customer satisfaction and ensures every product meets high quality standards. Their Stainless Steel 409 solutions are long lasting, affordable, and tailored to respond to the changing needs of various industries, hence a go-to partner globally.
Stainless Steel 409 Slitting Coils and Coils are mainly made up of chromium (10.5–11.75%) and less carbon content, with trace amounts of nickel, silicon, and manganese. Such composition offers high oxidation and corrosion resistance in mildly corrosive and high-temperature conditions. These coils provide tensile strength of ~450 MPa, yield strength of ~205 MPa, and elongation of approximately 30%. They are appreciated for their formability, weldability, and long life, so they are used in applications subjected to moderate environmental and thermal stress, especially in vehicle and industrial applications.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Stainless Steel 409 Coils and Slitting Coils offer excellent corrosion resistance, particularly in moderately corrosive environments like automotive exhaust systems and industrial applications. They are highly heat-resistant, performing well at elevated temperatures without compromising structural integrity. The low carbon content ensures good weldability and prevents carbide precipitation during welding. With a tensile strength of approximately 450 MPa and good formability, these coils are versatile and durable. Their affordability, combined with superior resistance to oxidation, makes them an ideal choice for cost-effective solutions in applications requiring corrosion and heat resistance.
