Material Characteristics

The Q&T steel AISI 4140 has a high tensile strength and toughness, which makes it frequently used for highly stressed components in machinery and plant engineering. The mechanical properties of the material can be adapted very flexible to the occurring loads by subsequent heat treatment processes. When it comes to additive manufacturing specific alloy compositions and optimized process parameters must be used for defect-free processing due to the limited weldability

  1. 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.
  2. Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
