Description
1.4512 ESU, also known as AISI 409, is a ferritic stainless steel known for its good corrosion resistance, excellent formability, and high-temperature strength. Enhanced through the Electro Slag Remelting (ESR) process, which improves its purity and mechanical properties, this material is particularly suitable for applications in the automotive, chemical processing, and construction industries. It is often used for exhaust systems, heat exchangers, and structural components that require durability and resistance to oxidation. At Rosswag, we utilize 1.4512 ESU for open-die forging and precision machining, ensuring the production of robust and reliable components. Its good weldability and formability make it a versatile choice for industrial applications requiring long-lasting performance, corrosion resistance, and strength.
