... Abstract The primary objective of carburizing and hardening gears is to secure a hard case and a relatively soft but tough core. For this process, low-carbon steels (up to a maximum of approximately 0.30% carbon), either with or without alloying elements (nickel, chromium, manganese, molybdenum...

... involved in quenching, hardening, tempering, recarburizing, and cold treatment of carburized and quenched gears. Next, the chapter reviews the selection process of materials for carburized gears and provides information on carbon content, properties, and core hardness of gear teeth. The problems associated...

..., dimensional stability, and generation of quenching and grinding cracks. They also include insufficient case hardness and improper core hardness, influence of surface carbon content and grain size, internal oxidation, structure of carbides, and inclusion of noncarbide.

... to 8-pitch gears made mostly from 8620H steel. This procedure was used to monitor the process variation in carburizing for surface hardness, effective case depth, and core hardness. The test pin diameter chosen was based on the gear tooth thickness and the fact that the test pin center cooling rate...

... of choice is H13, which is classified as a deep-hardening chromium hot-work steel containing 5% Cr and 0.40% C. This steel can be readily water cooled while in service and has a good toughness factor after nitriding—provided that the preheat treatment has been done correctly in terms of core hardness...

... of 0.30 to 0.50% are carbonitrided to case depths up to approximately 0.3 mm (0.01 in.) when a combination of a reasonably tough, through-hardened core and a hard, long-wearing surface is required (for example, transmission gears). Steels such as 4140, 5130, 5140, 8640, and 4340 for applications...
