Introduction to Dipti Metal Industries' Expertise in ASTM A995 CD3MWCuN Valves
Dipti Metal Industries proudly stands as the largest global ASTM A995 CD3MWCuN Manufacturer in Mumbai, India, a premier A995 CD3MWCuN supplier in India, A995 CD3MWCuN stockist, and leading A995 CD3MWCuN exporter from India of Cast Super Duplex Stainless Steel Valves. Designated as **Grade 6A** (UNS J93380) under ASTM A890/A995, CD3MWCuN is the cast equivalent of Wrought Super Duplex 2507, further enhanced with Tungsten (W) and Copper (Cu), making it comparable to the performance of **Zeron 100**. This alloy is utilized in the most demanding environments where standard Duplex 2205 (CE3MN) is insufficient. The combination of high Chromium (24.0-26.0%), Molybdenum (3.0-4.0%), and Nitrogen (0.20-0.30%) guarantees a **PREN value well above 40**, ensuring exceptional resistance to localized corrosion, especially in high-temperature, high-chloride environments like offshore oil and gas platforms.
We specialize in manufacturing and supplying the full spectrum of CD3MWCuN valves, including Ball Valves, Gate Valves, Globe Valves, and Check Valves, certified for critical high-pressure, severe corrosion service. The alloy's characteristic Duplex microstructure provides high tensile strength (min. 100 ksi) and a minimum yield strength of 65 ksi, nearly double that of austenitic stainless steels. Our meticulous control over the casting and heat treatment process ensures the optimal Ferrite-Austenite phase balance (typically 40-60% Austenite), which is crucial for achieving the specified mechanical and corrosion properties. Our robust inventory confirms our status as the biggest A995 CD3MWCuN Stockist in India, enabling quick turnaround for global projects.
NOTE: For Super Duplex grades like CD3MWCuN, extreme care is taken during fabrication and heat treatment to maintain the PREN value and prevent the formation of harmful brittle phases. CD3MWCuN must not be used above 315°C (600°F) to avoid 475°C embrittlement.

ASTM A995 CD3MWCuN Valves — Frequently Asked Questions
CD3MWCuN is a Super Duplex alloy (Grade 6A) with high levels of Chromium (Cr), Molybdenum (Mo), and Nitrogen (N), resulting in a Pitting Resistance Equivalent Number (PREN) generally above 40. This provides superior resistance to chloride pitting, crevice corrosion, and stress corrosion cracking (SCC) compared to standard Duplex 2205.
Grade 6A is the designation for Cast Super Duplex Stainless Steels with a nominal 25% Chromium (2507 type). CD3MWCuN (UNS J93380) is the casting alloy containing Tungsten and Copper, often likened to the proprietary Zeron 100 grade, specializing in highly aggressive marine and chemical environments.
No. Like all Duplex alloys, CD3MWCuN has a strictly defined maximum service temperature of 315°C (600°F). Exposing the valve to temperatures above this limit for extended periods risks forming harmful brittle phases (e.g., sigma phase), which significantly reduces impact toughness and corrosion resistance.
The main advantage is in critical environments with high chloride concentrations and high operating pressures. CD3MWCuN provides corrosion resistance far beyond that of standard Duplex (2205/CE3MN), specifically resisting corrosion in hot seawater applications where standard Duplex would fail, combined with a higher guaranteed minimum yield strength.
