Linde LLC, located in Bridgewater, New Jersey, USA, a member of The Linde Group, has introduced Hydroflex, an advanced atmosphere control system that allows clean and bright oxide-free annealing of steel, stainless steel, copper, bronze or brass. The system can also be used in sintering and brazing applications.
“The Hydroflex advanced atmosphere control can use one or more carrier gases – nitrogen or argon – to maintain the furnace pressure while a controlled ratio of hydrogen helps prevent oxidation,” explains Akin Malas, Head of Application Technology, Metals & Glass Market, Linde LLC.
“Uses go beyond annealing,” added Grzegorz Moroz, Program Manager, Heat Treatment and Atmospheres, Linde LLC. “The Hydroflex control system can help optimise your process efficiency and enhance productivity of your process regardless of whether you are annealing, sintering or brazing copper, steel, stainless steel, bronze or brass,”
“First, it contributes to repeatable parts quality. In addition, a bright oxide-free finish means less rework, and a high reliability process means higher productivity,” added Moroz.
Linde offers a variety of advanced gas control technologies and engineering services for heat treatment furnaces. In addition, engineers at Linde Application Technology Centers can develop new gas supply systems for heat treatment processes and improve the control systems of existing processes. Metallography laboratory services include material analyses, scanning electron micrography (SEM) and a variety of hardness tests.
