Introduction to Dipti Metal Industries' Expertise in ASTM A995 CD3MN Valves
Dipti Metal Industries proudly stands as the largest global ASTM A995 CD3MN Manufacturer in Mumbai, India, a premier A995 CD3MN supplier in India, A995 CD3MN stockist, and leading A995 CD3MN exporter from India of Cast Duplex Stainless Steel Valves. CD3MN (UNS J92205) is the cast, lower carbon equivalent of the widely used Wrought Duplex 2205, specified under ASTM A890 Grade 4A / A995. Its microstructure is a near-equal balance of Austenite and Ferrite, granting it approximately **twice the minimum yield strength of standard austenitic stainless steels (304L/316L)** along with vastly improved resistance to Chloride Stress Corrosion Cracking (SCC) and superior pitting/crevice corrosion resistance (PREN typically > 30).
We specialize in the manufacturing and supply of the entire ASTM A995 CD3MN valve lineup, including Ball Valves, Gate Valves, Globe Valves, and Check Valves, custom-built for high-pressure systems in chloride-rich or corrosive environments. Key to the performance of CD3MN is its carefully controlled chemistry, notably the Nitrogen (N) content (0.10-0.30%), which improves weldability, localized corrosion resistance, and ensures a stable Duplex microstructure. We focus on manufacturing CD3MN valves with controlled heat treatment to achieve the correct ferrite-austenite balance (40-60% Austenite) for optimal performance. Our extensive inventory makes us the biggest A995 CD3MN Stockist in India, ensuring prompt delivery to global marine, chemical, and Oil & Gas projects. Dipti Metal is your trusted A995 CD3MN Valve Supplier in Mumbai for high-strength, SCC-resistant fluid control solutions.
NOTE: CD3MN is the preferred lower-carbon variant over CE3MN in some critical welding applications. For applications with extremely high corrosion requirements (PREN > 40), consider our Super Duplex grades like ASTM A995 CD3MWCuN (Super Duplex Grade 6A) Valves. CD3MN must not be used above 315°C (600°F).
ASTM A995 CD3MN Chemical Composition and Mechanical Properties
Our CD3MN castings adhere strictly to the ASTM A995/A890 Grade 4A specification for Duplex Stainless Steel Castings, ensuring the high strength and corrosion resistance required for Duplex 2205 performance.
| Element | CD3MN (Grade 4A) Composition (%) | Element | CD3MN (Grade 4A) Composition (%) |
|---|---|---|---|
| Iron (Fe) | Balance (BAL) | Carbon (C) | 0.03 max |
| Chromium (Cr) | 21.0–23.5 | Silicon (Si) | 1.00 max |

ASTM A995 CD3MN Valves — Frequently Asked Questions
The wrought equivalent alloy to ASTM A995 Grade CD3MN (Grade 4A) is Duplex 2205 (UNS S32205/S31803). CD3MN is the Cast Duplex Grade which is the lower carbon version of CE3MN, sharing the same key properties.
CD3MN (Duplex 2205) provides excellent resistance to chloride stress corrosion cracking (SCC) and high resistance to pitting and crevice corrosion, thanks to its high Chromium, Molybdenum, and Nitrogen content (PREN > 30).
No. Duplex stainless steels are severely limited in high-temperature service. CD3MN valves must not be exposed to temperatures above 315°C (600°F) for extended periods, as this will lead to the formation of brittle phases and loss of impact toughness/corrosion resistance.
CD3MN offers roughly twice the minimum yield strength of standard austenitic stainless grades like CF3M (316L). This high strength allows for robust performance and reduced wall thickness/weight in high-pressure applications.
