high-temperature alloy
we can ensure that the steel we source is tailored to the needs of our valued customers.
high-temperature alloy line

High-temperature alloys or superalloys are another challenge. They contain chromium for oxidation resistance and elements like aluminum, vanadium, tantalumniobium, titanium, zirconiumhafnium, and other elements added as gamma prime formers, which strengthen the matrix of the materials by the precipitation of the gamma prime intermetallic compounds that are stable at high temperatures.

High-temperature alloy introduction

Hydrogen would form hydrides in case of tantalum, niobium, titanium, zirconium and hafnium and cause hydrogen embrittlement in superalloys. 

Carbon is also not desired in these materials as the carbides would reduce the amount of gamma prime precipitates. Oxides of aluminum, titanium, zirconium, and hafnium cannot be reduced by either carbon or hydrogen. Vacuum or argon is the atmosphere of choice in most cases.

Application of high temperature-alloys

Heat resistance applications typically require consistent performance at temperatures over 1200°F (649°C). 

Alloys with high performance levels of oxidation resistance, creep strength, stress rupture life, and tensile strength contribute to heat resistance properties.

Heat-resistant metals are found in many different industries including:

Automotive    Aerospace    Aviation    Ceramic    Chemical

Construction    Electronics    Glass    Machine Shops    Military    Petrochemical
