FEATURES

Inductoheat, Inc.

From selecting the right material for parts a company wants to manufacture, to designing the induction heat-treating system it will require, here’s your source for expert guidance.

Gear companies interested in manufacturing a new part that requires induction heat-treating have options to consider. One involves devoting resources to handling everything internally — from designing the part, to researching the proper materials, to choosing the best heat-treating technique — which can result in quite an investment of both time and capital. Another requires […]

Bearing Reliability in Rebuilt Gearboxes

SKF’s bearing vibration analyzer has proven invaluable during the maintenance and refurbishment of gearboxes and other critical units in demanding applications.

Fifty years of ongoing development has given SKF a bearing vibration analyzer that can probe deep into rotating bearings while they are under load. Initially used as a production line tester, it’s now proving invaluable during the maintenance and refurbishment of gearboxes and other critical units in demanding applications such as aerospace. SKF vibration testing […]

Low Pressure Carburizing for Transmissions

Low pressure carburizing and high pressure gas quenching have become a preferred technology for the latest generation of transmissions. Here’s why.

With the many advances that have taken place to improve quality in the gear industry, it is only logical that heat treat services would have to evolve to meet the increased demands of precision gear manufacturers. For decades gear manufacturers used atmosphere batch furnaces with integral oil quenches for the case hardening process. In recent […]

Retained Austenite Stabilization

Case-hardened components made of low-alloy steels often have retained austenite in the case after quenching, which can be transformed to martensite by further cooling of the component, even if the austenite stabilizes during aging at room temperature.

The phenomenon of retained austenite stabilization in tool steels is well documented [1,2]. When a steel with a martensite finish temperature (Mf) below room temperature is quenched, some austenite is retained in the microstructure. If cooling is immediately continued to a temperature below the Mf, virtually all the austenite present at room temperature can be […]

Dimensional Stability in Cryogenic Treatments

The following article describes the results of academic and industrial research into the influence of cryogenic treatment on dimensional stability in gear steel.

When cryogenically treated, case carburized steel (En 353) showed tremendous improvement in wear resistance [1]. This is due to the microstructural changes such as conversion of retained austenite to martensite and precipitation of fine alloying carbides. The equivalent grades of En 353 are BS-815M17 and IS-15NiCr1Mo12. In an earlier research work on En 353 it […]

Terry McDonald: Site Safety

In light of the swine flu pandemic, how do we protect ourselves from contamination in the workplace, and also while traveling on work-related projects?

The recent H1N1 swine influenza outbreak, which was eventually classified as a global pandemic by the World Health Organization, made me think about a number of issues communicable diseases present in the industrial workplace, and also to those of us who travel a great deal in our jobs. On one hand, you want to protect […]

Material selection can be the difference between whether a gear fails or fulfills its function beautifully

The selection of gear material is complex, and must be related to the specific duty and life required by the application. The compatibility with the mating gear’s material, chemistry, composition, processing capabilities, mechanical properties, and cost must always be evaluated. High-cost material does not ensure the best gear. Some applications may have requirements where aluminum, […]

Q&A with Thomas Passek

Executive Director ASM Heat Treating Society

Could you give us a brief overview of the society’s origins and structure? In 1913 William Park Woodside, who was trained as a blacksmith and worked for the Cadillac Motor Car Company, met with 18 colleagues in Detroit and formed The Steel Treaters’ Club. As it grew it split into two factions, one based in […]
