Modified alloy compositions for Metal AM

Why to have an eye on the chemical alloy composition of your MetalAM materials 🔍 Learn more on MaterialsMonday

We want to share a very interesting paper with you.

The colleagues from Bochum, Wuppertal, Dortmund and Bremen published an article regarding the "Impact of the Allowed Compositional Range of Additively Manufactured 316L Stainless Steel on Processability and Material Properties".

As the chemical alloy compositions of the three 316L batches are still according to ASTM A276, you wouldn't expect any impact on LPBF processing or resulting material properties.

But the results showed significant deviations:

🔵 Solid-state cracking
🔵 Austenitic/Ferritic solidification path
🔵 Corrosion resistance
🔵 Elongation at fracture

At the end, an LPBF-optimized compositional range for the 316L is derived.
