409 Stainless Steel Data Sheet , 10mm Stainless Steel Plate For Automotive Exhaust Pipe

1)Introduction:

Alloy 409 is a general purpose, chromium, titanium stabilized, ferritic stainless steel whose primary application is automotive exhaust systems. It contains 11% chromium which is the minimum amount for the formation of the passive surface film which gives stainless steels their corrosion resistance. It combines good elevated temperature corrosion resistance with medium strength, good formability, and overall cost. Alloy 409 resists corrosion strongly compared to carbon steel and is used as an alternative to carbon steel in mildly challenging environments where its high resistance to corrosion and high temperature oxidation gives an advantage. It is commonly used in applications where appearance is a secondary quality to mechanical properties and corrosion resistance.

If you desire a stainless steel whose mechanical properties highly outshine its physical appearance than 409 stainless steel is your perfect match. 409 Stainless is ideally used in scenarios where a need for oxidation or even corrosion protection is wanted. As a titanium stabilized ferritic stainless steel, 409 is most commonly used in automotive exhaust systems where the environment can be quite taxing on the lifetime of the steel.

Standards:

ASTM/ASME: UNS S40900

EURONORM: FeMi35Cr20Cu4Mo2
DIN: 2.4660

2)Applications:

Although Alloy 409 is designed principally for the automotive exhaust industry, it has been successfully used in other industrial applications as well. Some examples of applications that call for Alloy 409 include:
Automotive exhaust systems
Catalytic converters
Mufflers
Tailpipes
Farm equipment
Structural support and hangers
Transformer cases
Furnace components
Heat exchanger tubing
