AISI 316L, additively manufactured, PBF-LB (St_T_30_h_2)

This is supplemental data for the following material description: AISI 316L

The elastic properties (Young's modulus, shear modulus) of austenitic stainless steel AISI 316L were investigated between room temperature and 900 °C in an additively manufactured variant (laser powder bed fusion, PBF‑LB/M) and from a conventional process route (hot rolled sheet). The moduli were determined using the dynamic resonance method. The data set includes information on processing parameters, heat treatments, grain size, specimen dimensions and weight, Young’s and shear modulus as well as their measurement uncertainty.

The dataset was generated in an accredited testing lab using calibrated measuring equipment. The calibrations meet the requirements of the test procedure and are metrologically traceable. The dataset was audited as BAM reference data. The dataset was made available under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/legalcode).
