Introduction to Dipti Metal Industries' Expertise in ASTM A995 CD4MCuN Valves
Dipti Metal Industries proudly stands as the largest global ASTM A995 CD4MCuN Manufacturer in Mumbai, India, a premier A995 CD4MCuN supplier in India, A995 CD4MCuN stockist, A995 CD4MCuN dealer, A995 CD4MCuN distributor, and leading A995 CD4MCuN exporter from India of Cast Duplex Stainless Steel Valves. Designated as **Duplex Grade 1B** (UNS J93372) under the ASTM A890/A995 specifications, CD4MCuN is distinguished by its Ferritic-Austenitic microstructure combined with a significant **Copper (Cu)** addition (2.75–3.25%). This Copper content is specifically engineered to enhance resistance to corrosive environments where other stainless or duplex steels fail, primarily in contact with mildly reducing media like sulfuric acid.
We ensure that our CD4MCuN castings maintain the required mechanical properties, including a minimum tensile strength of 100 ksi and minimum yield strength of 70 ksi. This high strength allows for robust valve design in high-pressure piping systems. Our state-of-the-art casting and heat treatment processes ensure the optimum phase balance, which is critical for preventing Chloride Stress Corrosion Cracking (SCC) and achieving maximum localized corrosion resistance (Pitting Resistance Equivalent Number, PREN, is typically > 34). Our focus on metallurgy makes us the most reliable A995 CD4MCuN Valve Supplier in Mumbai for the Chemical and Fertilizer industries.
NOTE: CD4MCuN is particularly valuable when Sulfuric Acid is the primary corrosive agent, providing a cost-effective alternative to more expensive nickel-based alloys in specific concentration and temperature ranges. Due to the risk of 475°C embrittlement, CD4MCuN must not be used above 315°C (600°F).

ASTM A995 CD4MCuN Valves — Frequently Asked Questions
CD4MCuN is a copper-enhanced Duplex Stainless Steel. The addition of Copper (Cu) improves the alloy's resistance to mildly reducing corrosive media, particularly sulfuric acid (H₂SO₄) and phosphoric acid, an advantage not typically found in standard Duplex grades like 2205.
'C' is Corrosion resistance, 'D' for Duplex structure, '4' for 4% nominal Nickel, 'M' for Molybdenum, 'Cu' for Copper, and 'N' for Nitrogen. It is designated Grade 1B under ASTM A890/A995.
Like all Duplex stainless steels, CD4MCuN should not be used in continuous service above 315°C (600°F). Prolonged exposure above this temperature can lead to 475°C embrittlement, resulting in a severe loss of toughness.
Due to its Duplex structure (Ferrite-Austenite), CD4MCuN offers a minimum yield strength of 70 ksi (485 MPa), which is roughly double that of standard cast austenitic grades like CF8M (316), providing excellent structural integrity for high-pressure systems.
