WebCadmium Plating Material Spec: QQ-P-416 Type II. Color: Iridescent Yellow (free-running) Color: Olive Drab (screw-locking) Silver Plating. Recommended to reduce galling of threads at high temperatures. For use up to 1200°F. Highly recommended with inserts made from Inconel X750. Material Spec: QQ-S-365. WebLarge fragments or surface protrusions may be formed and the result is galling of the surfaces. Severe galling can result in the seizure of metal components. Materials which are highly ductile or which possess low work-hardening rates tend to be prone to galling. Austenitic stainless steels show a tendency to gall under certain conditions.

WebMinor galling may cause only slight damage to the thread surface and the installer may still be able to remove the fastener. However, in severe cases galling can completely weld … WebNitronic 60 is an anti-galling and wear resistant austenitic stainless steel. It provides a significantly lower cost alternative to combat wear and galling when compared with cobalt-bearing and high nickel alloys. The uniform corrosion resistance of Nitronic 60 is superior to 304 in most media. Chloride pitting resistance is superior to 316.

WebThe corrosion resistance of Armco NITRONIC 60 Stainless Steel falls between that of types 304 and 316.
