X2CrNi12 Ferritic Stainless Steel Plate/Coil EN 10088 Introduction
X2CrNi12 (material number 1.4003) is a low-carbon, chromium-nickel ferritic stainless steel standardized in EN 10088-1. It is characterized by:
- Good resistance to atmospheric corrosion, water, and mildly aggressive environments
- Excellent weldability without preheating, similar to carbon steel fabrication practices
- Higher strength than most austenitic stainless steels
- Magnetic behavior due to its ferritic microstructure
- Cost-effectiveness owing to low nickel content
Typical delivery condition is annealed and pickled, suitable for cold forming and structural applications. Commonly supplied as plate and coil for subsequent manufacturing.

Notes:
Additional information:
- Magnetic: X2CrNi12 is ferritic and therefore strongly magnetic.
- Weldability: Excellent; all common welding methods can be used (MIG, TIG, laser, resistance). Preheating is not required; interpass temperature should be kept below 150 °C to avoid grain growth. Filler metals: 309L or matching ferritic consumables may be used.
- Corrosion: Suitable for rural and urban atmospheric exposure, fresh water, and mildly acidic condensates. Not recommended for chloride-rich marine environments or strong acids.
- Formability: Good cold formability; minimum bending radius similar to structural carbon steels. Springback should be considered.
- Surface finish: Usually supplied as pickled and optionally skin-passed (2B, 2D, 2R).
- Heat treatment: Annealing at 700–780 °C followed by air cooling restores optimum properties after heavy cold working or welding.
All data based on EN 10088-1 and EN 10088-2; certain physical property values are typical and not part of the standard.
