1.4833 Stainless Steel Composition & Oxidation‑Resistant Properties
1.4833 (X12CrNi23‑13) is a high‑temperature oxidation‑resistant austenitic stainless steel grade under EN standards, equivalent to 309. With 22–24% chromium and 12–15% nickel, it offers excellent oxidation resistance above 1000°C, making it suitable for extreme high‑temperature service.
The grade performs reliably under thermal cycling, oxidizing atmospheres, and mildly sulfur‑containing environments. It is commonly used in furnace components, heat‑treatment fixtures, combustion chambers, insulation structures, and high‑temperature support parts. Weldability is good, enabling fabrication of heat‑resistant structures and liners. 1.4833 is supplied as plates, tubes, bars, and strips. It is widely used in furnace construction, heat‑treatment trays, combustion equipment, and high‑temperature transfer structures. As a high‑chromium austenitic heat‑resistant steel, it provides long‑term stability in severe oxidation environments.
