ASTM A380 & AMS2700

PASSIVATION is a process that creates an austenite layer on the surface of stainless steel, which drastically improves its corrosion performance. For materials such as AMS5678 this process is critical. One important thing to note is that if any soap coating is present on the wire, heat treatment scale or bloom needs to be properly removed prior to both NDT and PASSIVATION to ensure the process is effective. G&O operate a preclean in accordance with ASTM A380 and are NADCAP approved for Method 1 types 7 & type 8 (which are of course REACH compliant).

Our innovative passivation line is fully automated, we move the fluid not the parts!

I have been working with G&O since October 2019 and I could never say a bad word about this company. I have always been supported with important and critical items and as a company they are meeting my personal requirements. The business relationship with G&O is strong even during the hard times of the COVID-19 pandemic. G&O is self managing the VMI system each week I am up to date with any part number supplied by them. I would recommend anyone at anytime a collaboration with G&O. Tomasz Grabarek Material Controller - Incora
