Introduction to Dipti Metal Industries' Expertise in ASTM A494 CW12MW Valves
Dipti Metal Industries proudly stands as the largest global ASTM A494 CW12MW Manufacturer in Mumbai, India, a premier A494 CW12MW supplier in India, A494 CW12MW stockist, A494 CW12MW dealer, A494 CW12MW distributor, and leading A494 CW12MW exporter from India of Cast Nickel-Chromium-Molybdenum Alloy Valves (Hastelloy C-276). CW12MW is a high-performance alloy renowned for its exceptional versatility, providing resistance in both highly oxidizing and reducing corrosive environments. It is the material of choice for chemical processes where mixed acids, wet chlorine, or high concentrations of ferric and cupric chlorides are present—conditions that cause rapid failure in standard stainless steels and specialized reducing-only alloys. Its high content of Chromium (15.5-17.5%), Molybdenum (16.0-18.0%), and Tungsten makes it a robust, all-around corrosion solution.
We specialize in the manufacturing and supply of the entire ASTM A494 CW12MW valve lineup, including Ball Valves, Gate Valves, and Check Valves. This Nickel-based alloy offers outstanding localized corrosion resistance (pitting, crevice) and is used primarily in the as-welded condition due to its controlled, extremely low carbon and silicon content. Our valves consistently adhere to international standards, primarily ASME B16.34. Our inventory makes us the biggest A494 CW12MW Stockist in Mumbai, ensuring prompt delivery to chemical, pollution control, and other severe service projects globally. Dipti Metal is your trusted A494 CW12MW Valve Supplier in Mumbai for the ultimate, versatile corrosion performance.
NOTE: For applications with dedicated non-oxidizing (reducing) acid service, which requires zero Chromium content, consider the Nickel-Moly grade: ASTM A494 N12MV (Cast Hastelloy B) Valves.

ASTM A494 CW12MW Valves — Frequently Asked Questions
CW12MW (Hastelloy C-276) is a high Nickel-Chromium-Molybdenum alloy that offers exceptional resistance to both oxidizing and reducing media, unlike other specialty alloys. It is the most versatile corrosion-resistant material, ideal for environments involving wet chlorine gas, hypochlorite, and ferric and cupric chlorides, which are highly oxidizing.
CW12MW is primarily Nickel (balanced), with Chromium (15.5-17.5%), Molybdenum (16.0-18.0%), and Tungsten (3.75-5.25%). The combination of Chromium and Molybdenum provides superior resistance across a vast range of chemicals, including reducing and oxidizing acids.
No. Due to its extremely low carbon content and special alloying, Hastelloy C-276 is generally resistant to the formation of harmful grain-boundary precipitates in the heat-affected zone of welds. It can often be used in the as-welded condition in most chemical processes.
CW12MW valves are indispensable in Flue Gas Desulfurization (FGD) systems, Chemical Processing (especially those handling aggressive mixtures), Pulp & Paper (bleaching processes), and waste treatment environments.
