Stainless Steel Valve Casting
Neocast Alloys is a premier stainless steel valve casting manufacturer. Supplying CF8M, CF3M, and Duplex valve bodies for the world's most aggressive chemical and marine environments.
Stainless Alloys We Pour
As a custom alloy casting foundry, we manage over 50 different metallurgical grades. Our stainless steel valve castings strictly adhere to ASTM A351, A743, and A890 specifications.
Built for Severe Environments
Valves operating in petrochemical refineries, desalination plants, and food processing facilities cannot afford to corrode. As a specialized stainless steel valve casting manufacturer, we provide the metallurgical integrity these industries demand.
We leverage the investment casting process to produce valve body castings with near-net shape precision. Because stainless steel is notoriously difficult to machine due to work hardening, casting close to the final dimension saves our OEM partners significant CNC machining time and tooling costs.
Every CF8M and Duplex heat is verified via our in-house OES spectrometer. Combined with our ISO and PED certifications, we guarantee that your valve parts will meet rigorous international corrosion and pressure standards.
Frequently Asked Questions
Q.What makes stainless steel ideal for valve casting?
Stainless steel, particularly austenitic grades like CF8M (316), contains molybdenum and high chromium. This provides exceptional resistance to pitting, crevice corrosion, and chemical degradation, making it mandatory for food processing, marine, and petrochemical valves.
Q.Do you cast Duplex stainless steel valves?
Yes, we are experts in Duplex and Super Duplex stainless steel valve casting. These alloys provide superior strength and exceptional resistance to chloride stress corrosion cracking, ideal for offshore oil rigs and desalination plants.
Q.How do you ensure the chemistry of the stainless steel is correct?
Every heat is meticulously analyzed using an advanced Optical Emission Spectrometer (OES) before pouring. We ensure the chemical composition perfectly matches ASTM A351 or A890 standards and provide EN 10204 3.1 material certificates.
Q.Can you machine stainless steel valve castings?
Yes. Stainless steel is known to work-harden and can be difficult to machine. By using investment casting to achieve near-net shape, we minimize machining. Our in-house CNC shop then performs the final precision threading and flange facing.
