Properties of Cases Treated with High-Temperature Vacuum Carburization

Carburizing continues to be one of the basic thermochemical treatments used for industrial steel. With the development of the industry, carburizing has evolved from its simplest forms, such as pack treatment, to advanced vacuum technologies. At present, vacuum carburization technology is replacing the older technologies and is more and more widely used, especially in the […]

CASE STUDY: Company: Praxair Distribution, Inc. Customer: ALD Thermal Treatment, Inc.

In the past several years, heat treating companies have experienced a significant supply disruption in generated acetylene. Additionally, generated acetylene may not offer the purity required for important manufacturing processes such as the vacuum carburizing function of heat treating for gears. ALD Thermal Treatment Inc. (ALD) recognized the need to find a stable, reliable supply […]

Cures for Heat Treaters Headaches

Heat treaters all over the world encounter similar problems with atmosphere furnaces. These problems not only cause operational headaches in the daily lives of furnace personnel; they significantly affect the bottom line. The most common is creep distortion of alloy components under carburizing conditions, eventually leading to catastrophic failure. This paper explores both conventional and […]

Simulation of Gas Quenching of Steel Parts

One major difference between immersion quenching and gas quenching is the presence of boiling during the early stages of quenching in oil or water. The formation of a vapor phase has a significant effect on the overall and local heat removal rate from the parts being quenched and also on part distortion. With the absence […]

Inductive Spin Hardening of Gears: A Survey of Key Features and Benefits

A large part of the misunderstanding of induction hardening seems to stem from an incomplete grasp of the basic induction heating process. This is surprising, as the process itself is relatively easy to grasp once certain fundamental steps have been explained. Induction heating is quite literally heat that has been induced in a workpiece. Roughly […]
