Available in a vast size range (NPS 1/2″ – 36″), and pressure classes (ASME Class 150-1500, PN 10-250) for extreme industrial service. As an A351 CK3MCuN Valve Manufacturer in Mumbai and global leader, we ensure exceptional quality and material compliance from Mumbai, India.
Introduction to Dipti Metal Industries' Expertise in ASTM A351 CK3MCuN Valves
Dipti Metal Industries proudly stands as the largest global ASTM A351 CK3MCuN Manufacturer in Mumbai, India, a premier A351 CK3MCuN supplier in India, A351 CK3MCuN stockist, A351 CK3MCuN dealer, A351 CK3MCuN distributor, and leading A351 CK3MCuN exporter from India of Cast Super Austenitic Stainless Steel Valves. This grade, corresponding to Wrought 254-SMO, is designed for the most aggressive corrosive media that surpasses the capability of standard Molybdenum grades like 316L/317L (CF3M/CG3M). Its Pitting Resistance Equivalent Number (PREN) exceeding 40 is achieved through the synergistic alloying of very high Chromium, high Nickel, high Molybdenum (6.0-7.0%), and Nitrogen (0.18-0.24%), resulting in an alloy with exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
We specialize in the manufacturing and supply of the entire ASTM A351 CK3MCuN valve lineup, which includes Ball Valves (API 6D/API 608), Gate Valves (API 600), and Check Valves (API 594). As a low-carbon alloy (max 0.025%), it is weld-safe, preventing intergranular corrosion after welding. Its primary limitation is exposure to temperatures above 400°C due to the risk of detrimental intermetallic (Sigma) phase formation. Our valves consistently adhere to international standards, primarily ASME B16.34. Our inventory makes us the biggest A351 CK3MCuN Stockist in India, ensuring prompt delivery to global offshore and chemical projects. Dipti Metal is your trusted A351 CK3MCuN Valve Supplier in Mumbai for the ultimate in stainless steel corrosion performance.
NOTE: For applications with operating temperatures exceeding 400°C (752°F), alternative high-performance alloys such as ASTM A494 CW6MC (Hastelloy C276) Valves or Duplex grades like ASTM A995 CD3MN (Duplex 2205) Valves may be required.

Applications of ASTM A351 CK3MCuN Cast Stainless Steel Valves
ASTM A351 CK3MCuN Valves are essential for processes where Duplex stainless steels and high-grade 316/317L Molybdenum alloys fail, making them critical components in environments characterized by high chloride, bromide, or fluoride contamination.
- Offshore Oil & Gas: Seawater handling, cooling, and fire-fighting systems, where hot seawater often causes rapid failure in 316L.
- Flue Gas Desulfurization (FGD) Systems: Used in wet scrubber environments where concentrated sulfuric acid and chlorides lead to severe corrosion.
- Chemical Processing: Handling aggressive acids and chemicals containing concentrated halides (e.g., concentrated sulfuric acid, phosphoric acid).

ASTM A351 CK3MCuN Valves — Frequently Asked Questions
CK3MCuN (Cast 254-SMO) is classified as a Super Austenitic grade due to its extremely high content of Chromium (20%), Nickel (18%), and critically, Molybdenum (6-7%), plus Nitrogen (0.18-0.24%). This combination gives it a Pitting Resistance Equivalent Number (PREN) above 40, offering near-immunity to chloride stress corrosion cracking and superior resistance to hot seawater compared to standard 316/317L grades.
The 'CK3MCuN' is a complex designation: 'C' denotes Corrosion-resistant service, 'K' is a specific compositional range, '3' is for low carbon (L-grade, max 0.025%), 'M' for Molybdenum, 'Cu' for Copper, and 'N' for Nitrogen, which is crucial for strength and corrosion resistance.
While CK3MCuN offers excellent corrosion resistance, its primary limitation is service temperature, typically limited to 400°C (752°F) or less. Higher temperatures can lead to the formation of harmful intermetallic phases (like Sigma phase), which severely reduce ductility and corrosion resistance.
CK3MCuN is essential in environments where conventional stainless steels fail, including Offshore Oil & Gas (fire water systems, heat exchangers), Flue Gas Desulfurization (FGD) scrubbers, Chemical Process Units (handling halides/bromides), and Pulp & Paper bleaching systems.
