..., with light loads and some lubrication, yellow brasses may not gall, but wear could be an issue. Leaded yellow brasses wear significantly self-mated or in contact with steel or other metals. The insoluble lead nodules in their microstructure that make them easy to machine also make these alloys prone...

... on them, and forging dies have hot steel rubbing on them. The H steels do not get very hard at 43 to 53 HRC. So, to prevent galling and adhesive wear, ejector pins and cores are often nitrided. Thus, a 53 HRC mold with 60 HRC core pins (nitrided H13) reasonably resists adhesive wear. Forging dies...

... to the higher strength and higher strain-hardening behavior of AHSS. These conditions lead to galling, abrasive and adhesive wear in the tool, and significantly reduce tool life. Figure 6.20 illustrates the complex tribological interactions that occur in forming AHSS to minimize/eliminate tribological...

These steels are often hardfaced on wear surfaces with hard, corrosion-resistant alloys such as Ni-Cr-B and Fe-Co-Cr hardfacings. There are cast equivalents of all the stainless steels if an application requires castings. Galling...
