Material Characteristics
The austenitic stainless steel alloy AISI309 is characterized by a high temperature resistance and strength. The material is scale-resistant up to approx. 1,000 °C and has a good weldability. Due to these properties, the material is mostly used in furnace and apparatus engineering. Additive manufacturing offers a wide range of possibilities with this alloy for functional optimization, for example to build high-performance heat exchangers.

| Hardness | HV | 225 ±5 |
- The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
- Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
