The electropolishing process POLIGRAT E 520 is suitable for workpieces made from iron and mild steel. The surface becomes bright, burr-free, clean and smooth on a microscopic scale. POLIGRAT E 520 is free from hexavalent chromium.

Depending on the alloy and structure, the workpieces can be polished bright to satin finish. Alloyed and hardened tool steels can be deburred

POLIGRAT E 520 removes affected material surfaces without mechanical, thermical and chemical impact and developes the pure properties of the material.
