what’s the corrosion resistance difference between 26S8-3D and V26S02-3AGV ?

The stud V26S02-3AGV is identical in form, fit and function to the old version 26S8-3D. The only difference is the surface treatment. 26S8-3D was coated with zinc and yellow chromate (and is now obsolete) corrosion resistance according salt spray test DIN EN ISO 9227 NSS 48 hours no zinc corrosion, 120h no parent material corrosion V26S02-3AGV is coated with zinc, clear passivated and sealed. corrosion resistance according to salt spray test DIN EN ISO 9227 NSS 120 hours no zinc corrosion, 240 hours no parent material corrosion. As you can see, we have improved the corrosion resistance with the change of the surface treatment which is an advantage.
