This information sheet recommends powder metallurgy, PM, steelmaterials and metallurgical quality characteristics for use inspecifying PM gearing. It identifies specifications andrequirements for various PM steel materials for as–sintered,through hardened or sinter hardened, carburized case hardened, andinduction hardened gearing. Requirements are coded by process andclass number, the latter based on the density of the PM gear teeth.Characteristics covered include material composition, density,sinter processing (conventional, high temperature and sinterhardening), secondary heat treatments and post heat treatmentprocessing, and their associated inspections.
