Product Description
X1NICRMOCU31-27-4 EN 10028-7 1.4563 EN1092-1 Type 11 Flange
1.4563 is a high-alloy austenitic stainless steel (also known as X2CrNiMnMoNNb21-16-5-3) developed for excellent corrosion resistance, especially in chloride-containing and acidic environments.
Chemical Composition

C (Carbon) ≤ 0.03
Si (Silicon) ≤ 0.7
Mn (Manganese) 2.0 – 7.0
P (Phosphorus) ≤ 0.03
S (Sulfur) ≤ 0.01
Cr (Chromium) 20 – 22
Ni (Nickel) 14 – 17
Mo (Molybdenum) 4.0 – 6.0
N (Nitrogen) 0.35 – 0.55
Nb (Niobium) 0.1 – 0.4
Fe (Iron) Balance
Key Composition Benefits
  • High Chromium (≈21%) + Molybdenum (≈5%) provide strong resistance to pitting and crevice corrosion, especially in chlorides (e.g., seawater, process brines)
  • High Nickel (≈15–16%) stabilizes the austenitic structure and improves toughness
  • Added Nitrogen (0.35–0.55%) boosts strength and further improves pitting resistance
  • Niobium contributes to stabilization against intergranular corrosion and helps control microstructure
For exact values required for design or certification, always check a mill certificate or the relevant material standard (e.g., EN 10088) for the specific product and supplier. Small variations within these ranges are normal and can be critical in specific applications.
