Product Description
EN 1.4509 AISI 441 Cold Rolled Ferritic Stainless Steel Sheet And Coil
Ferritic SS 441
SS 441 stainless steel is double balanced out ferritic hardened steel with a chromium content of up to 18% and low carbon. 441 stainless steel has better high temperature strength as compared to grade 409L in addition to 439 great resistance in various exhaust gas conditions and better oxidation resistance at elevated temperatures.
Corrosion Resistance
SS 441 or UNS S44100 is ferritic stainless steel with niobium providing the steel good oxidation and corrosion resistance. SS 441 is resistant to corrosion in solutions of various halogen-free organic and inorganic compounds when tested in a wide temperature and concentration range.
With its titanium and niobium content, the risk of sensitization for intergranular corrosion is reduced enough when compared to grades with non-stabilized ferritic stainless steels. It can surpass many sufficiently diluted organic and mineral acids considering the temperature and concentration of the solution.

| 1.4509 | X2CrTiNb18 | 441 | S43932 | 441 |
Chemical composition ( weight % )
| Grade | C | Si | Mn | P | S | Cr | Ni | Nb | N | Ti |
| 441 | 0.03 max | 1.00 max | 1.00 max | 0.040 max | 0.030 max | 17.5~19.5 | 1.00 max | 0.3+9XCmin, 0.9 max | 0.03 max | 0.1~0.5 |
3. The mechanical properties of grade 441 stainless steel are displayed in the following table.
| Properties | Metric | Imperial |
| Tensile strength (annealed) | 489 MPa | 70900 psi |
| Yield strength (@temperature 871 °C/ 1600 °F ) | 2.90 MPa | 421 psi |
| Modulus of elasticity | 220 GPa | 31908 ksi |
| Elongation at break (in 2", annealed) | 35.90% | 35.90% |
| Hardness, Rockwell B (annealed) | 80 | 80 |
4.Applications
Type 441 stainless developed for mufflers and exhaust emission control systems.
Due to its alloy composition, this steel exhibits scaling resistance up to over 950 °C in continuous
service and good corrosion resistance under exhaust system loads.
5. Product forms
Hot and Cold-rolled wide coil, strip, sheet and plate, slit strip, cut sheets
6.Packing
1.packing the carbon coil with polyethylene
2.fixed with steel ring
3.use mental band strapping to protect the steel coil
Is 441 stainless steel magnetic?
The 441 flat rolled stainless steel possesses magnetic quality in all conditions. Type 441 is an 18% chromium, dual stabilized ferritic stainless steel with corrosion resistance similar to that of 304/304L stainless steel.
Which is better SS 304 and SS 441?
When we compare SS304 Vs SS 441, SS441 comes with slightly higher proof strength than regular austenitic SS 304 in combination with lower work hardening. SS 441 can be used in the temperature range where chromium carbides would precipitate in non-stabilized ferritic grades.
