FeCrAl mesh is a woven wire mesh made from Iron-Chromium-Aluminum (FeCrAl) alloys, known for their exceptional high-temperature oxidation resistance, corrosion resistance, and electrical heating properties. It is available in different grades such as 0Cr25Al5, 0Cr23Al5, Kanthal D, Kanthal A-1, Kanthal APM, etc.
Key Properties of FeCrAl Mesh:
– Iron (Fe): Base metal (~70-80%)
– Chromium (Cr): 15-22% (enhances oxidation resistance)
– Aluminum (Al): 4-7% (forms a protective alumina scale at high temps)
– Minor Elements: Yttrium (Y), Rare Earths (for improved scale adhesion)
– Continuous Use: Up to 1300°C (2372°F)
– Short-Term Exposure: Up to 1400°C (2552°F)
– Forms a protective Al₂O₃ (alumina) layer at high temps, preventing further oxidation
– Excellent resistance to oxidizing atmospheres, sulfur, and carburizing environments
– Performs better than stainless steel (304, 310) in high-temperature applications
– Resists thermal cycling and thermal shock
