SS6521 Spherical Duplex 2209 Stainless Steel Powder

Spherical Duplex Stainless Steel Powder 2209 Description

Spherical Duplex 2209 Stainless Steel Powder is an advanced alloy that exhibits properties comparable to the known Duplex stainless steel 2205 but differs significantly in its chemical composition. The nickel content in SS2209 is increased to approximately 9%, compared to the 5% in 2205, leading to notable changes in the microstructure. This alteration enhances certain properties of the alloy, making it suitable for specific applications in welding technology and 3D printing.

The increased nickel content in SS2209 contributes to improved corrosion resistance, especially in environments exposed to chlorides and other aggressive conditions. However, the higher nickel content also affects the material's behaviour during the forging process, where forging defects may occasionally occur.

Due to its unique combination of properties, SS2209 is ideal for applications requiring high strength, excellent corrosion resistance, and the ability to withstand harsh environments. The alloy is particularly well-suited for welding processes and additive manufacturing (3D printing), as it provides the flexibility to create complex geometries while maintaining the integrity and performance of the material.
