ASTM 409 - EN 1.4512 - Ferritic Stainless Steel - Stainless steel

ASTM 409/EN 1.4512. a titanium-stabilized ferritic stainless steel, is frequently known as "muffler grade stainless steel" as the prevalent application of this material is in automotive exhaust systems. This material offers strength and corrosion resistance at high temperatures, making it ideal for exhaust system fabrication and welding. Its sleek metallic finish is an added benefit to its durability and performance capabilities.

Essential details

ASTM 409 is a weldable ferritic stainless steel with good oxidation resistance in dry air. This product is also available as low-carbon AISI 409L. Its corrosion resistance is limited in applications with increased corrosiveness. Because of its titanium alloying, it can be welded in all dimensions without becoming susceptible to intergranular corrosion. It is possible to use 1.4512 in high-temperature applications, for instance in automotive exhaust systems, where it is often used to replace aluminium-coated carbon steel.

- Heat exchangers

- Acid and nitrogen oxide pipelines

- Acid storage tanks

- Acid transport tanks

- Dairy, fruit and vegetable and brewery industries

- Textile industry

- Household appliances
