Short answer: High-temperature oxidation is the growth of a metal oxide scale in hot air or flue gas; resistance comes from chromium, aluminium or silicon that form a slow, adherent protective film, so alloy choice and coating decide how long a part survives in service.
At a Glance
Oxidation Kinetics & Scale
Scale grows by metal/oxygen diffusion; a dense, adherent Cr2O3 or Al2O3 film slows it dramatically, while iron oxide on plain steel spalls and regrows. This links to Metal High Temperature Oxidation Guide duty, Metal Creep Guide und Metal Thermal Fatigue Guide; microstructure context in Grain Structure Metals.
Alloy Selection
Carbon steel scales above ~550 C; low-chromium steel to ~650 C; 304/316 (Stainless Steel 316 Properties, Stainless Steel 304 Properties) to ~870 C; 310 and Nickel Alloy Supplier (Inconel/Hastelloy, Hastelloy Guide, Inconel Vs Hastelloy Guide) to 1100-1200 C. Compare Refractory Metals Supplier for extreme heat and Duplex Stainless Supplier for moderate.
Protection & QA
Apply aluminide/chromide coatings or use Metal Surface Treatment Guide, control atmosphere, and inspect scale and wall loss with Metal Ndt Guide. Certificate chemistry and service temp per Mill Test Certificate Guide; relate to Mill Test Certificate Guide callouts.

Häufig gestellte Fragen
Growth of an oxide scale on a hot metal surface in air or flue gas; it thins the section and can spall under thermal cycling.
High-chromium/nickel alloys (310 SS, Inconel, Hastelloy) and aluminised coatings resist scaling to the highest temperatures.
Its chromium forms a thin, adherent, self-healing Cr2O3 film that blocks further oxygen diffusion.
Plain carbon steel scales rapidly above about 550 C; low-alloy and stainless extend that to 650-870 C and beyond.
