Products Features
Comprehensive Corrosion Resistance – Tolerance for Both Oxidizing and Reducing Media
The unique chemical composition (Ni-23Cr-16Mo-1.6Cu) enables it to exhibit excellent corrosion resistance in oxidizing acids (such as nitric acid, iron-ion containing sulfuric acid) and reducing acids (such as dilute sulfuric acid, hydrochloric acid), outperforming traditional C-type alloys (e.g., C-276).
Excellent Resistance to Localized Corrosion
High molybdenum (16%) and chromium (23%) content endow it with exceptional resistance to pitting and crevice corrosion (particularly effective in chloride and halogen media), along with good stress corrosion cracking resistance.
Superior Resistance to Reducing Acids
It exhibits very low corrosion rates in media such as dilute sulfuric acid, hydrochloric acid, formic acid, and acetic acid, making it suitable for equipment like reactors, tanks, and heat exchangers.
Good Formability and Weldability
It can be formed hot or cold using conventional techniques. It has excellent weldability (suitable for GTAW, GMAW, SMAW, etc.) and no post-weld heat treatment is required (unless specifically needed), facilitating the manufacture of complex equipment.

High-temperature performance
It exhibits good oxidation resistance in oxidizing atmospheres below 1000°C. However, this alloy is primarily designed for medium-to-low temperature corrosion environments (long-term use at ≤ 450°C).
Pitting Resistance Equivalent Number (PREN): The PREN is calculated as %Cr + 3.3×%Mo ≈ 22 + 3.3×16 ≈ 74.8, which is significantly higher than that of 316L (approximately 25) and C-276 (approximately 67).
Critical Pitting Temperature (CPT): In a 10% FeCl₃·6H₂O solution, the CPT is ≥ 85°C, outperforming both C-276 and 625 alloys.
Applicable Media:
1. Dilute sulfuric acid, hydrochloric acid, phosphoric acid, formic acid, acetic acid
2. Acidic solutions containing halides
3. Flue gas desulfurization (FGD) slurries
4. Oxidizing-reducing mixed acids (e.g., nitric acid + hydrochloric acid)
5. Seawater, brine, and brackish water
6. Organic chemicals (e.g., acetic anhydride, phenol)
