2.Product description: Grade 409 stainless steel is a Ferritic steel that offers good
mechanical properties and high-temperature corrosion resistance. It
is commonly considered as a chromium stainless steel, with
applications in exhaust systems of automobiles and applications
that demand weldability. Grade 409 steels are also available in highly stabilized forms,
such as grades S40930, S40920 and S40910. The stability of these
grades is provided by the presence of niobium, titanium, or both,
in the composition of steels. 3.Chemical Composition about stainless steel coil/sheet | Classification | Grade | Main Chemical Compositon | | C | Si | Mn | P | S | Ni | Cr | other | | AUSTENITE | 301 | 0.15 | 1.00 | 2.00 | 0.045 | 0.03 | 6.00-8.00 | 16.0-18.0 | | | 301L | 0.03 | 1.00 | 2.00 | 0.045 | 0.03 | 6.00-8.00 | 16.0-18.0 | N≤0.20 | | 304 | 0.08 | 1.00 | 2.00 | 0.045 | 0.03 | 8.00-10.5 | 18.00-20.00 | | | 304L | 0.03 | 1.00 | 2.00 | 0.045 | 0.03 | 9.00-13.0 | 18.00-20.00 | | | 316 | 0.08 | 1.00 | 2.00 | 0.045 | 0.03 | 10.0-14.0 | 16.00-18.00 | Mo 2.0-3.0 | | 316L | 0.03 | 1.00 | 2.00 | 0.040 | 0.03 | 12.0-15.0 | 16.00-18.00 | Mo 2.0-3.0 | | 321 | 0.08 | 1.00 | 2.00 | 0.045 | 0.03 | 9.0-13.0 | 17.00-19.00 | Ti5XC%↑ | | FERRITE | 409L | 0.03 | 1.00 | 1.00 | 0.040 | 0.03 | — | 10.5-11.75 | Ti6xC% | | 430 | 0.12 | 0.75 | 1.00 | 0.040 | 0.03 | — | 16.00-18.00 | | | 436L | 0.03 | 1.00 | 1.00 | 0.040 | 0.03 | — | 16.00-19.00 | | | 444 | 0.03 | 1.00 | 1.00 | 0.040 | 0.03 | — | 17.00-19.00 | Mo 0.75-1.5 | | MARTENSITE | 420J2 | 0.26-0.40 | 1.00 | 1.00 | 0.040 | 0.03 | — | 12.00-14.00 | |
