409 stainless steel data sheet. North america s largest supplier of 409 stainless steel metric sheets. Nas 409 is an 11 chromium stabilized ferritic stainless steel. 409 stainless is used when corrosion protection is needed beyond a carbon steel capacity. En 10088 2 astm a240 en 10028 7 en 10259 iso 9445.

Parker steel company. Grade 409 stainless steels have excellent resistance to exhaust gas and atmospheric corrosion superior to that of 410 martensitic grades with 12 chromium and 3cr12. Although regarded as a general purpose chromium stainless steel the almost exclusive application for grade 409 is automotive exhaust systems. Automotive exhaust systems and heat exchangers.

Our inventory of stainless steel alloy grades include t409 409 al t439 t441 18crcb stainless steel. Manganese mn 1 00 max. Alloy 409 is a general purpose chromium titanium stabilized ferritic stainless steel whose primary application is automotive exhaust systems. Ak steel 409 ultra form stainless steel provides an outstanding combination of improved forming ridging and roping.

However the corrosion resistance is lower than that of grade 430 steels containing 17 chromium. Ati 409hp uns s40900 ferritic stainless steel was introduced by ati in 1961 to provide improved oxidation and corrosion resistance for automotive exhaust systems in comparison to carbon steel. These benefits are achieved through precise control of chemistry and thermomechanical processing from melting to finishing. The alloy was designated mf 1 indicating its end use.

Composition wt carbon c 0 03 max. North america s largest supplier of 409 stainless steel metric sheets. Straub metal international founded in 1970 is a worldwide distributor of type 409 stainless steel. T409 t439 are offered in sheet coil strip coil panels plates washers.

Its applications are those where appearance is a secondary consideration to mechanical properties and corrosion resistance particularly at high temperatures and where some weldability is required.
