409 Stainless Steel Coil Product Attributes
409 Stainless Steel Coil Product Introduction
Applications of 409 Stainless Steel Coil
409 stainless steel coil is widely used in automotive exhaust systems, furnace parts, and heat exchangers due to its excellent heat and oxidation resistance. It is also found in industrial machinery and kitchen appliances where moderate corrosion resistance is required. The coil’s durability at high temperatures and resistance to scaling make it ideal for components exposed to continuous heat and corrosive environments.
Specifications and Key Properties
Typical 409 stainless steel coils have thicknesses ranging from 0.3mm to 100mm and widths between 1000mm to 2000mm. The material contains 10.5-11.75% chromium and is stabilized with titanium to improve weldability and reduce carbide precipitation. Mechanical properties include a tensile strength of 380-560 MPa, yield strength of 205 MPa or higher, and elongation of 20-25%. Common finishes are 2B, BA, No.1, and No.4, suitable for different surface requirements.
Performance Advantages and Suitable Industries
The titanium stabilization in 409 stainless steel coils enhances resistance to grain boundary corrosion and improves performance in welded applications. Their moderate corrosion resistance surpasses that of carbon steel, making them a cost-effective choice in automotive, industrial, and architectural applications. Their good machinability and strength ensure wide usage in manufacturing exhaust components, heat exchangers, and heat-resistant equipment.
