Introduction to Dipti Metal Industries' Expertise in ASTM A494 N12MV Valves
Dipti Metal Industries proudly stands as the largest global ASTM A494 N12MV Manufacturer in Mumbai, India, a premier A494 N12MV supplier in India, A494 N12MV stockist, and leading A494 N12MV exporter from India of Cast Nickel Alloy Valves. N12MV (UNS N30012) represents the original Cast Hastelloy B grade, highly valued for its exceptional performance in severely **reducing (non-oxidizing)** corrosive conditions. This alloy's composition, high in Nickel (Ni) and Molybdenum (Mo), provides robust and stable corrosion resistance where alloys containing Chromium (Cr) would be rapidly attacked. The low Silicon and Iron content contribute to its excellent resistance to Hydrochloric Acid and reducing Sulfuric Acid across critical concentrations and operating temperatures.
We specialize in the manufacturing and supply of N12MV Ball Valves, Gate Valves, Globe Valves, and Check Valves, certified for systems exposed to high concentrations of non-oxidizing acids. Our expertise ensures that these castings meet the strict chemical and mechanical requirements (min. yield strength 40 ksi) necessary for reliable, long-term service in the most aggressive chemical environments. Due to its superior resistance in reducing media, N12MV remains a preferred material for specific chemical processes despite the existence of newer B-series variants. Our comprehensive stock makes us the biggest A494 N12MV Stockist in India, ensuring rapid delivery to chemical processing and pharmaceutical projects worldwide. Dipti Metal is your trusted A494 N12MV Valve Supplier in Mumbai for specialized reducing acid service.
NOTE: N12MV is an older generation Hastelloy B grade. While excellent in pure reducing acids, its high Carbon content (0.12% max) means it is susceptible to reduced ductility and intergranular corrosion if improperly heat-treated. We apply strict heat-treatment controls to ensure optimal performance. It must NEVER be used in the presence of oxidizing impurities.
ASTM A494 N12MV Chemical Composition and Mechanical Properties
Our N12MV castings adhere strictly to the ASTM A494 N12MV specification, maximizing Molybdenum for reducing acid resistance.
| Element | N12MV (Cast Hastelloy B) Composition (%) | Element | N12MV (Cast Hastelloy B) Composition (%) |
|---|---|---|---|
| Nickel (Ni) | Balance (BAL) | Carbon (C) | 0.12 max |
| Molybdenum (Mo) | 26.0–30.0 | Silicon (Si) | 1.0 max |
| Iron (Fe) | 4.0–6.0 | Manganese (Mn) | 1.0 max |
| Chromium (Cr) | 1.0 max | Sulphur (S) | 0.04 max |
| Copper (Cu) | 0.5 max | Phosphorus (P) | 0.04 max |
N12MV's performance relies heavily on its high Nickel and Molybdenum content; other elements are kept low to prevent corrosion acceleration in reducing conditions.

ASTM A494 N12MV Valves — Frequently Asked Questions
N12MV is a Nickel-Molybdenum alloy (Hastelloy B-type) designed for exceptional resistance to severe reducing (non-oxidizing) environments. Its primary industrial use is handling Hydrochloric Acid (HCl), Sulfuric Acid (H₂SO₄), and Phosphoric Acid, especially in high concentrations and elevated temperatures.
N12MV has a wider composition range for Molybdenum (26.0-30.0%) and higher Carbon content (0.12% max) compared to N7M (30.0-33.0% Mo, 0.07% max C). The N12MV grade is considered the more traditional Hastelloy B casting grade, while N7M is a modified version for even greater non-oxidizing acid performance and thermal stability.
The Iron (Fe) content is restricted to 4.0-6.0% (balance) to maintain the alloy's primary corrosion resistance. Hastelloy B alloys are extremely sensitive to oxidizing impurities. Keeping Iron, Chromium (max 1.0%), and other secondary elements low is essential to prevent rapid corrosion in the presence of trace oxidizing salts or agents.
N12MV is highly vulnerable to oxidizing corrosive media. It should not be used in the presence of oxidizing acids (like Nitric Acid) or even minor oxidizing impurities like ferric or cupric chlorides, which would cause extremely rapid, catastrophic corrosion.
