Introduction to Dipti Metal Industries' Expertise in ASTM A494 M35-1 Valves
Dipti Metal Industries proudly stands as the largest global ASTM A494 M35-1 Manufacturer in Mumbai, India, a premier A494 M35-1 supplier in India, A494 M35-1 stockist, and leading A494 M35-1 exporter from India of Cast Monel 400 (UNS N24135) Nickel Alloy Valves. M35-1 is the casting equivalent of Wrought Monel 400 (UNS N04400), a versatile Nickel-Copper alloy celebrated for its exceptional resistance to **Hydrofluoric Acid (HF)** and its remarkable performance in various **seawater** environments, including high-velocity and stagnant conditions. Unlike many alloys, M35-1 does not rely on a Chromium oxide film for corrosion protection, enabling its successful use in reducing (non-oxidizing) acidic conditions and specific alkaline media.
The Monel 400 chemistry (Ni min 63.0%, Cu 26.0-33.0%) also imparts high strength (min. yield strength 25 ksi) and toughness, even down to cryogenic temperatures. We specialize in the manufacturing and supply of the entire M35-1 valve lineup, including Ball Valves, Gate Valves, Globe Valves, and Check Valves, certified for critical processes such as HF alkylation in the petroleum industry and marine desalination plants. Our adherence to stringent casting and quality control protocols ensures that our M35-1 valves provide the necessary balance of corrosion resistance and mechanical integrity. Our comprehensive stock makes us the biggest A494 M35-1 Stockist in India, ensuring prompt supply to specialized chemical and marine projects worldwide. Dipti Metal is your trusted A494 M35-1 Valve Supplier in Mumbai for robust, hydrofluoric acid-resistant fluid control solutions.
NOTE: Monel 400 (M35-1) is not subject to 475°C embrittlement like Duplex/Super Duplex and retains its toughness down to sub-zero temperatures, making it versatile across a wide service temperature range.
ASTM A494 M35-1 Chemical Composition and Mechanical Properties
Our M35-1 castings strictly conform to the ASTM A494 M35-1 specification, a Nickel-Copper alloy renowned for its stability and specific acid resistance.
| Element | M35-1 (Cast Monel 400) Composition (%) | Element | M35-1 (Cast Monel 400) Composition (%) |
|---|---|---|---|
| Nickel (Ni) | Balance (BAL) (Min 63.0) | Carbon (C) | 0.35 max |
| Copper (Cu) | 26.0–33.0 | Silicon (Si) | 1.25 max |

ASTM A494 M35-1 Valves — Frequently Asked Questions
The wrought equivalent alloy to ASTM A494 Grade M35-1 (UNS N24135) is Monel 400 (UNS N04400). It is a Nickel-Copper alloy renowned for its high strength and excellent resistance to a wide range of corrosive environments, particularly flowing seawater and Hydrofluoric Acid.
M35-1 (Monel 400) is one of the few metallic materials highly resistant to Hydrofluoric Acid (HF) and its solutions, including anhydrous HF. It is the material of choice for piping and valves handling HF in most concentrations, as well as for superior resistance in rapidly flowing brackish water and seawater.
M35-1 is not suitable for highly oxidizing acid service (like Nitric Acid) and is vulnerable to stress corrosion cracking (SCC) in aerated Hydrofluosilicic Acid (H₂SiF₆) and in some power generating environments where high-purity steam is present.
M35-1 is a Nickel-Copper alloy. It contains 63% minimum Nickel (Ni) and 26.0%–33.0% Copper (Cu). This simple binary alloy system provides a favorable combination of high strength and excellent corrosion properties without relying on Chromium or Molybdenum.
