What Is 1.4845 Stainless Steel?
EN 1.4845, also known as X8CrNi25-21, is a High-Temperature Austenitic Stainless Steel containing approximately 25% Chromium and 20% Nickel, designed for excellent Oxidation Resistance Up To 1100–1150°C. It is commonly used in:Furnace parts,Heat exchangers,Radiant tubes,High-temperature ducts and headers.
Its Low Carbon Content (max 0.04%) improves weldability and reduces the risk of carbide precipitation compared to similar grades like 1.4841 (310).
