Hydrogen in steel is bad news for mechanical properties and the metal's chemical characteristics. A recent Key to Steel article details the chemistry of hydrogen problems. The feature also discusses the sources of hydrogen pick up in steel production from the addition of materials and components, such as lime and coke.  

Albany Times Union State transportation engineers are watching closely to see whether four experimental holes cut in the steel of the Patroon Island Bridge will lead to a solution for a persistent problem with cracking on the bridge's floor beams. Workers suspended beneath the westbound lanes cut elliptical holes in two floor beams in an effort to help increase bridge flexibility.

The National Institute of Standards and Technology has published a new database on the properties of solid materials at temperatures ranging from cryogenic to room temperature. Officially known as NIST Standard Reference Data Database #152, the Cryogenic Materials Properties Database is available online, free of charge. Learn more .

Asia Pulse Pte Ltd. Australian steelmaker OneSteel has signed an agreement with the University of NSW in which waste plastic will replace up to 30% of the coke and coal used in their steelmaking process. The technology has been tested for the past two years at OneSteel's Sydney plant in Rooty Hill.
