This book is a combination of a metallographic atlas for steels and cast irons and an introductory textbook covering the fundamentals of phase transformations and heat treatment of these materials. Every important stage of processing, from casting to cold working is clearly discussed and copiously illustrated with metallographs that show the obtained structures, both desired and those achieved when deviations occur. A valuable companion even for experienced steel practitioners.
September 18, 2017X-ray diffraction analysis indicates that the hardened case consists of a mixture of expanded austenite and expanded martensite.
September 13, 2017Outokumpu Oy, Finland, announces that Finnish liquefied natural gas tank manufacturer LNGTainer has launched a new tank that brings together two innovations – LNGTainer's game-changing tank container, and Outokumpu's unique austenitic stainless steel grade, Supra 316plus (EN 1.4420, UNS S31655).
September 10, 2017EOS, Germany, introduces StainlessSteel 17-4PH IndustryLine, an iron-based metal alloy powder made by a technology that includes a specially developed process parameter for additive manufacturing on the EOS M 290 metal system.
September 06, 2017Outokumpu Oy, Finland, has received Pratt & Whitney's LCS (laboratory control at source) approval for its stainless steel bar products manufactured at its Richburg mill in South Carolina.
August 31, 2017Nitrocarburizing in a carrier gas to which (initially solid) urea was added led to a fast growth of the expanded austenite zone. The gaseous decomposition products of urea that develop in the furnace are highly activating, which means that activation and nitrocarburizing are achieved simultaneously.
August 18, 2017For nitrocarburizing or consecutive carburizing and nitriding, the typical stress profile is smoother than for nitriding only.
July 20, 2017The graph shows X-ray diffraction patterns of nitrided (and carburized) stainless steel AISI 316.
