| DESCRIPTION | 409L is a titanium stabilized ferritic stainless steel. It exhibits good high temperature oxidation resistance and good corrosion resistance in low corrosive media. Because of the titanium addition and the low carbon and nitrogen content, this steel shows good forming and weldability. | ||||||||

| CORROSION RESISTANCE | 409L offers mechanical and corrosion resistance better than carbon steels. It also shows adequate oxidation resistance to be used in exhaust systems. | ||||||||
| STRESS CORROSION CRACKING | As ferritic stainless steel the 409L exhibits good stress corrosion cracking resistance. | ||||||||
| HIGH TEMPERATURE OXIDATION RESISTANC | The maximum scale-breaking temperature for 409L is 800℃ in continuous exposure. The maximum working temperature may vary strongly depending on the involved media. | ||||||||
| SURFACE CLEANING | Wash the surface with neutral soap and water applied with a cloth or a brush without scratching the stainless steel. Then, always rinse the stainless steel with water to remove completely the cleaning agent. Finally, it is recommended to dry the surface to preserve a good superficial condition. In severe environments, a frequent cleaning is strongly recommended. | ||||||||
| SPECIFICATIONS | It can be delivered according to EN-10088-2 and ASTM/A-480M standard requirements. | ||||||||
