In 2017, ASM’s Heat Treating Society R&D Committee established a new recognition for the best papers in the heat treat industry each year. To be considered for the ASM Heat Treating Society Prime Contributor recognition, papers must appear in either the HTPro quarterly newsletter or be published in ASM’s Heat Treat conference proceedings.

More than 125 presentations of original, unpublished work will be delivered when the ASM Heat Treating Society convenes for its 29th conference and exhibition in Columbus, Ohio, October 24-26. The information exchanged in these sessions – as researchers and practitioners share their latest discoveries, theories, and advancements – will have a significant impact on design and manufacturing innovation as well as the fortunes of industry.

P20 mold steel is seldom carburized for molds used in compression molding, particularly for molding the more abrasive plastics.
Continue readingOne Minute Mentor: Quenching of Hot-Work Tool Steels
Hot-work steels range from high to extremely high in hardenability, so it is possible for them to achieve full hardness by cooling in still air. However, this is not recommended, because intense embrittlement occurs after slow cooling from hardening temperature.

Because of their tungsten content, F-steels form hard tungsten carbides.

Excellent results are obtained by austenitizing water-hardening tool steels in a slightly oxidizing atmosphere, as indicated by the data in the graph, obtained in tests on type W2.

Austenitizing temperatures for water-hardening tool steels normally vary from 1400 to 1550°F. Higher temperatures are sometimes used for special purposes.
