Characteristics of ASTM A268 TP409 Stainless Steel Tube
- Basic corrosion and oxidation resistance
- Composition balanced for optimum formability
- Weldable only in thin sections due to fully ferritic structure
- Low cost and limited cost variation due to low alloy content
Overwiew:
The vehicle exhaust system must withstand aggressive conditions from high temperatures, sulphuric acid condensates and de-icing salts at the manifold end.
High temperatures, sulphuric acid condensates and de-icing salts from the end of the manifold. Given the severity of these conditions, the surprisingly, the 11% chromium grade 409 has been meeting this challenge for many years.Exhaust components also need to be bent, expanded and pressed into a variety of complex shapes.The ability of ferritic steels to meet these formability requirements is phenomenal.
Application:
petroleum
chemical
war and electricity industries
food processing
medical industry
machinery
hardware fields.
