SPARK SGHT Ultra-High Temperature Electric Heating Alloy (Fe-Cr-Al)
SGHT is a high-end Iron-Chromium-Aluminum (Fe-Cr-Al) ultra-high temperature electric heating alloy developed by Shougang Gitane. Diverging from traditional smelting methods, SGHT utilizes refined master alloys and advanced powder metallurgy technology. This process involves high-temperature hot isostatic pressing to produce billets, followed by precision cold and hot processing.
Product Introduction
Specifically designed for extreme environments, SGHT can operate at temperatures up to 1420℃. In June 2020, Shougang Gitane successfully developed the first domestic ultra-high temperature Fe-Cr-Al tube using this technology, bridging a critical gap in the high-end electric heating alloy field and reaching world-class standards.
Product Features
