409L stainless steel is a type of ferritic stainless steel that has been widely used in various industries, from automotive to food and beverage. It is a highly versatile material with excellent corrosion resistance and good formability. In this blog post, we’ll discuss the composition, physical properties, mechanical properties, and uses of 409L stainless steel.
The chemical composition of 409L ss is as follows: iron (Fe) balance; chromium (Cr) 11.5-14%; molybdenum (Mo) 0.5-1%; manganese (Mn) 1%; phosphorus (P) 0.045%; sulfur (S) 0.03%; silicon (Si) 1%.
| Grade | C (max) | Si (max) | Mn | Cr | Ni | P(max) | S (max) | Ni(max) | Other Elements |
|---|---|---|---|---|---|---|---|---|---|
| SS 409L | 0.03 | 1.00 | 1.00 | 10.50-11.70 | 1.5 max | 0.040 | 0.030 | 0.50 | Ti=6X(C+N)Min., 0.75Max |
409L grade stainless steel has a density of 7.86 g/cm3 and a melting point range between 1390-1450 °C. It has an elongation at a breakage rate of 22%, good thermal conductivity, and a low thermal expansion coefficient which makes it suitable for use in high-temperature environments such as automotive exhaust systems.
409L SS is a ferritic material which means it has low ductility and poor weldability compared to austenitic steels such as 304 or 316 grades. The mechanical properties of 409L stainless steel include a tensile strength between 360-550 MPa, a yield strength between 170-380 MPa, and an ultimate tensile strength between 370-570 MPa. It also exhibits good fatigue resistance up to 8 ksi in cyclic stress applications due to its ferritic microstructure.
| Element | Tensile Strength % | Yield Strength % | Elongation | Hardness (HRB) max |
|---|---|---|---|---|
| SS 409L | 380 | 170 | 20 | 88 |
| STANDARD | UNS | WNR. |
|---|---|---|
| SS 409L | S40903 | 1.4512 |
Due to its good corrosion resistance and formability, stainless steel 409L is well suited for use in corrosive environments such as automotive exhaust systems or food processing equipment where exposure to chemicals or extreme temperatures can be expected. Its low cost makes it attractive for use in mass-production applications such as automotive mufflers or kitchen sinks where cost savings are desired without sacrificing performance or durability. Additionally, due to its ferritic microstructure, it can also be used in applications requiring high fatigue resistance, such as powertrain components or other parts subject to cyclic loading conditions over extended periods of time.
