WE-S100.25 Sponge Iron Powder
WE-S100.25 is a sponge iron powder grade for welding consumable applications requiring high iron content, controlled particle size distribution, stable flowability and reliable processing performance.
Product Overview
WE-S100.25 is a sponge iron powder grade developed for welding electrodes, flux-cored wires, metal-cored wires and related welding consumable formulations.
With high iron content, controlled apparent density, stable Hall flow and suitable particle size distribution, WE-S100.25 supports consistent mixing, processing and application performance.
The grade can be reviewed according to the target welding process, chemical specification, particle size requirement, current supplier grade and final product performance.
