SDSS(Supper Duplex Stainless Steel) is a material that has both austenite and ferrite phases.
It has excellent machinability/excellent mechanical properties/excellent corrosion resistance/high low-temperature impact toughness.
In this case study, multi-material samples of SS316L and SDSS were manufactured by MX-Fab, the possibility of multi-material was evaluated by mechanical property evaluation/microstructure analysis/bonding interface analysis and selecting the optimum heat treatment for securing ferrite contents within the range.
Finally, SDSS(inner) + SS316L(Outer) multi-material valve production and accepted the pressure test twice the operating pressure without any problem.
