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.
