409 Stainless Steel Sheet Properties

Stainless steel alloy 409 is a smart choice when budget matters.

409 stainless steel sheet properties.

Grade 409 stainless steel is a ferritic steel that offers good mechanical properties and high temperature corrosion resistance. 409 is a titanium stabilised ferritic stainless steel. It is commonly considered as a chromium stainless steel with applications in exhaust systems of automobiles and applications that demand weldability. Automotive exhaust systems and heat exchangers.

Most applications involve engine exhaust systems such as automotiove exhausts catalytic converters and mufflers. 409 stainless is used when corrosion protection is needed beyond a carbon steel capacity. It forms a light protective rust layer in exhaust gas atmospheres and is readily weldable. When it comes to strength at high temperatures and the ability to resist oxidation 409 stainless steel alloy does better than a carbon steel.

409 is the perfect grade stainless steel to be used in automotive applications where visual appeal is not a top priority. It contains 11 chromium which is the minimum amount for the formation of the passive surface film which gives stainless steels their corrosion resistance.
