SUMO TEC - Application Colors

In order to facilitate our customers in selecting the correct grade for their applications, ISCAR has developed new coating processes for the new SUMO TEC grades which will feature different colors for easy identification. All former SUMO TEC grades featured the same gold color.
The new coating technology improves the insert life by 5 to 12%, compared to the previous coatings.
6015 and 6025
which are used for stainless steel
(ISO M materials) will be identified by
a bright purple color.

CVD Coating
