Surface treatments compatible with our ETG® 88 and ETG® 100 steels include: hot-dip galvanizing, electrogalvanizing, chrome plating, nickel plating, black oxide coating (blackening), etc. The presence of manganese sulfides in the steel means that special care needs to be taken during pickling and neutralizing operations (for more information, please refer to DIN ISO 50969-1). To achieve the best results, the finishing process should be carried out on pre-ground material and the process temperature should not exceed 500 °C. Most surface finishing methods can also be applied to our ETG® 25 steel, such as electrogalvanizing, chrome plating, nickel plating and black oxide coating (blackening).
