2205 sample TIG Brush/TB-25 Cleaned – Copper Sulfate Test

Gauge Industrial and Environmental Pty Ltd was commissioned by Ensitech Pty Ltd. to conduct a study into the passivation of 2205 and 2507 duplex stainless steel after the use of Ensitech’s TIG Brush™ employing TB-25Weld Cleaning Fluid for Stainless Steel.

This study determined that the use of the TIG Brush™ as per Ensitech’s use recommendations with TB-25 fluid provides effective passivation of 2205 and 2507 duplex stainless steel welds compliant via the relevant passivation verification sections of standard methods ASTM A967/A967-13M “Chemical Passivation Treatments for Stainless Steel Parts, as well as complying with ASTM A380/A380M-13 “Cleaning, Descaling and Passivation of Stainless Steel Part, Equipment, and Systems.
