ASTM A268 TP405 Stainless Steel Seamless Tube - Key Application Advantages

 

  • Excellent Cost-Effectiveness & Weldability
  • As a 12% chromium ferritic stainless steel, TP405 offers good corrosion resistance at a significantly lower material cost than austenitic grades (e.g., 304). Its low carbon content and ferritic structure ensure easy welding and formability, making it an economical choice that balances performance and budget, ideal for components requiring subsequent fabrication.
  • Good Corrosion & Oxidation Resistance
  • Provides superior overall resistance to corrosion and oxidation compared to carbon steel, withstanding atmospheric exposure, steam, water, and many weak corrosive media. Suitable for automotive exhaust systems, heat exchanger bundles, and structural components in mildly corrosive environments, effectively extending service life.
  • Excellent Machinability and Formability
  • The material offers good plasticity and toughness, making it highly suitable for cold bending, flaring, flattening, and other forming processes. It can be easily shaped into complex parts, which is why it is widely used in applications with aesthetic and shape requirements, such as automotive trim, exhaust tailpipes, and architectural decorative components.
  • Reliable Structural Integrity
  • Manufactured using a seamless process, the tube body has no weld seams, ensuring a uniform and dense structure. This provides higher reliability and safety when the tube is subjected to pressure, vibration, or bending loads, making it suitable for fluid conveyance or as a mechanical structural component.
  • Broad Standard Compliance & Applicability
  • The product is manufactured in strict compliance with international standards such as ASTM A268, guaranteeing stable quality and high dimensional accuracy. This allows it to seamlessly integrate into the supply chains and design requirements of various global industries, including automotive manufacturing, general engineering, and decorative construction, ensuring wide applicability.
