AISI 409 Cuộn dây thép không gỉ – Product Overview

The AISI 409 Cuộn dây thép không gỉ is a ferritic stainless steel grade designed primarily for automotive and industrial applications. Known for its excellent resistance to corrosion, nhiệt, and oxidation, AISI 409 is particularly favored for components exposed to high-temperature environments. Composed mainly of chromium (10.5-11.75%) and iron, this grade of stainless steel provides good strength and durability at an affordable cost. It is often used in exhaust systems, heat exchangers, and other parts that require good thermal stability and moderate corrosion resistance. At Kim loại Yuanchi, we offer AISI 409 stainless steel coils in various thicknesses, widths, and finishes to meet the specific needs of your project.

Unique Features of AISI 409 Cuộn dây thép không gỉ

• Heat Resistance: AISI 409 is highly resistant to heat and oxidation, making it a great choice for applications exposed to high temperatures, such as automotive exhaust systems and industrial furnaces.
• Moderate Corrosion Resistance: While not as resistant as austenitic grades, AISI 409 offers good corrosion resistance to mild atmospheric and chemical exposure.
• Cost-Effective: As a ferritic grade, AISI 409 is more affordable than austenitic stainless steel grades like AISI 304, making it an economical choice for industries requiring durability without the high cost.
• Magnetic Properties: Unlike austenitic stainless steel, AISI 409 is magnetic, which can be beneficial in certain applications, such as exhaust systems and automotive components.
• Easy Formability: The material is easy to form and fabricate, allowing it to be used in a wide variety of manufacturing processes, including bending, Hàn, and deep drawing.
