Metallurgical Specifications for Powder Metallurgy, PM, Steel Gearing
This information sheet recommends powder metallurgy, PM, steel materials and metallurgical quality characteristics for use in specifying PM gearing. It identifies specifications and requirements for various PM steelmaterials for as--sintered, through hardened or sinter hardened, carburized case hardened, and induction hardened gearing. Characteristics covered include material composition, density, sinter processing (conventional, high temperature and sinter hardening), secondary heat treatments and post heat treatment processing, and their associated inspections. Topics related to gear design and rating such as case depth, stress (bending fatigue and contact fatigue capacity) and quality control systems are not included.
