Meltio Material Datasheet Rev 2.0 Meltio Mild Steel ER70-S ER70S-6/S42 4M21 3Si1 /AWSA5.18 ER70-S, also known as low alloy carbon steel or mild steel, is a highly versatile material due to its strength, ductility, and low cost. It is used in many applications, including construction, automotive and manufacturing. Its excellent weldability and machinability make it easy to work with, while its high ductility and toughness make it suitable for structural applications.

Meltio Material Datasheet Tomography Computed Tomography Scan of 3D printed sample part in ER70-S without detectable voids or defects. Resolution of 24 pm per pixel. The investigation reveals that the microstructure of the ER70-S specimens consists of a ferritic matrix intermixed with pearlite at the grain boundaries, wherein the interlayers exhibit larger grain sizes owing to the heat generated during material deposition. Relative density as 3D printed Mechanical Properties Results show that specimens printed using Meltio’s wire-laser metal 3D printed process perform at the same level as samples...
