Why Choose TISCO 439 Stainless Steel Sheet?

TISCO (Taiyuan Iron and Steel Group Corporation) is one of the world’s leading producers of stainless steel products. Their 439 stainless steel sheets are manufactured to meet the highest standards of quality and performance. The 2D surface finish and cold-rolled process ensure a smooth, matte surface that is resistant to oxidation and corrosion, making it ideal for auto exhaust systems, which must endure high temperatures and exposure to chemicals such as sulfur and nitrogen oxides.

Composition of TISCO 439 Stainless Steel

TISCO 439 stainless steel is an alloy composed mainly of iron, with significant amounts of chromium, nickel, and other trace elements. The specific composition provides enhanced resistance to heat and oxidation, making it ideal for automotive exhaust systems. The exact chemical composition of 439 stainless steel is as follows:

This composition ensures that TISCO 439 stainless steel performs well under high temperatures and offers outstanding resistance to oxidation, particularly in applications like auto exhaust systems that experience extreme thermal cycling.

Surface Finish: Cold Rolled 2D

The cold-rolled 2D surface finish gives the steel a smooth, dull matte finish, which enhances its aesthetic appeal while offering increased strength and durability. This finish is ideal for applications where appearance is important but functional characteristics like corrosion resistance and strength are paramount. Additionally, the 2D finish minimizes the formation of surface imperfections and is highly resistant to wear and tear.

Mill Edge: 4ft Width

The 4ft mill edge is a standard finishing that helps to retain the integrity of the sheet during processing, offering excellent dimensional accuracy. It is commonly used in industries where precise and consistent shapes and sizes are essential. The mill edge provides smooth, uniform edges for ease of handling, welding, and fabrication.

Applications of TISCO 439 Stainless Steel Sheet

1. Auto Exhaust Systems:
   The primary application for TISCO 439 stainless steel sheet is in the automotive exhaust industry. The alloy’s excellent resistance to high temperatures and corrosion, as well as its ability to withstand the harsh conditions within an exhaust system, makes it an ideal choice. The 2D surface finish enhances its ability to resist carbon buildup and oxidation, ensuring long-term performance in demanding conditions.

2. Industrial Applications:
   Beyond auto exhaust systems, TISCO 439 stainless steel sheets are also used in various industrial applications that require high heat resistance, such as heat exchangers, industrial chimneys, and other components exposed to high temperatures and aggressive environments.

3. Pressure Vessels & Boilers:
   TISCO 439 is also commonly used in the manufacture of pressure vessels and boilers, where strength, durability, and resistance to oxidation at high temperatures are essential.

4. Marine Equipment:
   The stainless steel’s ability to resist corrosion from saltwater makes it suitable for marine applications where durability and resistance to harsh environments are critical.

Benefits of Using TISCO 439 Stainless Steel for Auto Exhaust Systems

1. Corrosion Resistance: TISCO 439 stainless steel contains a high percentage of chromium, which creates a passive oxide layer on the surface that protects against corrosion. This makes it resistant to harmful agents like water, salt, and acids, which is especially important for exhaust systems that are exposed to varying environmental conditions.

2. Heat Resistance: The steel is designed to withstand extremely high temperatures without degrading, which is essential for automotive exhaust systems that are subjected to intense heat over extended periods.

3. Strength and Durability: TISCO 439 stainless steel maintains its mechanical properties even under stress and extreme temperatures. This is crucial for ensuring the structural integrity of exhaust systems and minimizing the risk of failure.

4. Excellent Formability: TISCO 439 stainless steel is highly malleable, allowing it to be easily formed into complex shapes required for automotive exhaust components.

5. Aesthetic Appeal: The 2D surface finish gives the material a clean and modern look, making it suitable not only for functional purposes but also for applications where visual quality matters.

Key Specifications

Conclusion:

TISCO 439 stainless steel sheet, with its cold-rolled 2D surface and 4ft mill edge, is the ideal choice for a wide range of applications, especially in the automotive exhaust industry. Its excellent heat resistance, corrosion resistance, and formability make it a superior material for systems that operate under extreme conditions.
