Galling resistance chart

WebGalling is also known as cold-welding. This is the process that can happen when the surfaces of a nut and bolt threads are placed under pressure. They begin to weld together due to friction and force. Stainless steel and aluminum are the most common metals to encounter the issue of galling, but it can happen in any metal. Webusually more galling resistant than machined surfaces. There is a rule of thumb that a hardness difference of 50 Brinell is required for effective prevention of galling and this is …

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. Webresistance. Pure nickel has a melting point of 1455°C but the phosphorus content of electroless nickel has a very sig-nificant effect on its melting point, as shown in Figure 2. The final melting point curve declines almost linearly from 1455°C to 880°C for an alloy containing 11% phosphorus.
