Product Summary
1.4435 stainless steel flanges offer superior corrosion resistance with low carbon content (≤0.03%) for excellent weldability. Enhanced nickel (12.5-15.0%) and molybdenum (2.5-3.0%) provide improved pitting resistance, making them ideal for pharmaceutical, biotech, and high-purity applications.

Product Description
X2CrNiMo18-14-3 EN 10222-5 1.4435 Corrosion Resistant Stainless Flanges
1.4435 is an austenitic stainless steel grade specifically designed for demanding applications in medical, pharmaceutical, and high-purity industries. This grade offers enhanced performance characteristics compared to standard 316L stainless steel, with tighter compositional controls and optimized alloying elements for superior corrosion resistance.
Chemical Composition
Element Content (Weight %)
C (Carbon) ≤ 0.03
Si (Silicon) ≤ 1.0
Mn (Manganese) ≤ 2.0
P (Phosphorus) ≤ 0.045
S (Sulfur) ≤ 0.015
Cr (Chromium) 17.0 – 18.0
Ni (Nickel) 12.5 – 15.0
Mo (Molybdenum) 2.5 – 3.0
N (Nitrogen) ≤ 0.11
Key Characteristics
  • Low Carbon Content (max. 0.03%): Minimizes risk of carbide precipitation and intergranular corrosion, ensuring excellent weldability and L-grade performance similar to 316L
  • Enhanced Nickel and Molybdenum: Higher content compared to standard 316L provides superior resistance to pitting and crevice corrosion
  • Stringent Impurity Control: Tight limits on phosphorus and sulfur result in cleaner steel with improved corrosion behavior
  • High-Purity Compatibility: Excellent suitability for high-purity media and superior surface finishes, including electropolished applications
Applications
This stainless steel grade is particularly favored in pharmaceutical processing, biotechnology equipment, chemical processing systems, and applications requiring ultra-clean environments where chloride-induced corrosion resistance is critical.
Always verify the exact specification from the material standard or mill certificate (such as EN 10088 data sheet), as minor compositional variations may occur depending on the manufacturer and product form.
