The Jominy end-quench test is used to measure the hardenability of a steel, which is a measure of the capacity of the steel to harden in depth under a given set of conditions. This article considers the basic concepts of hardenability and the Jominy test.

When you think of a wine cellar, you can picture the big barrels lining the floor. Oak, however, is not the only holding tank winemakers use. In fact, some wines cannot absorb the elements found in oak, so it’s steel to the rescue. Stainless steel was introduced to the wine industry in the 1950s for fermenting, aging and storage, and it is widely used today.

According to a report from the American Iron and Steel Institute (AISI), U.S. steel mills have increased their steel production total by 6.8% for the year to date through mid-April compared with the same time period in 2018.

It’s no secret that digitization is transforming the worldwide steel industry. Some companies, like Danieli, are capitalizing on this trend. Enrico Plazzonga, executive vice president, sales and marketing, Danieli Automation, explains the workings of a smart steel factory and the potential of data analytics and smart manufacturing.

Luxembourg-based ArcelorMittal announced it will idle a steel mill in Poland and reduce production at another facility in Spain. The steelmaker said it would cut European production by 3 million tons.

Researchers from the National University of Science and Technology developed a database that will help create new grades of steels. The goal is to speed up the process of creating innovative steel grades with specified strength and ductility.

ResponsibleSteel is the industry’s first multi-stakeholder certification initiative that aims to set a single, global standard for the entire mine-to-metal steel value chain. After a June meeting in London, formal market launch of the standard is expected by the end of the year.

According to the World Steel Association, steel production accounts for about 7% to 9% of all man-made carbon emissions. As a result, climate lobbyists are putting pressure on the industry to clean up its act. One possible solution is replacing coal with hydrogen, but it may not be a financially viable option for many companies.

Ultrasonic additive manufacturing (UAM) combines a unique room-temperature metal deposition process with the ease of traditional CNC milling. A patented ultrasonic print head is integrated into three-axis mills to create a hybrid additive-subtractive process.

As a way to reduce NASA’s yearly Space Station operations cost, they are opening the ISS for “private astronaut missions of up to 30 days.” The first mission will begin as early as 2020. NASA will initiate two private flights a year with each likely costing $50 million.
