dragline pin failure

Excavator Pin material

Jan 23, 2016The pin I would want to be softer, and use a lower carbon steel, like a 1050, but do a full heat treat, since it will have sufficient ductility at full hardness. I would want the pin to wear first. Galling is a type of corrosion from pieces that are fixed, and if they rotate with grease, galling is not really an issue. Get price
