Best Valve Materials for Metallurgical Industry Applications
When selecting valves for blast furnaces, smelting lines, steel mills, and non-ferrous metal plants, material choice is critical. The right valve materials can improve performance, reduce downtime, and ensure safety in harsh metallurgical environments.
At Yuanda Valve, we provide high-performance industrial valves with materials engineered for extreme temperature, pressure, corrosion, and erosion conditions. Our products are widely used in iron and steel production, copper smelting, aluminum refining, and other heavy-duty applications.
Common Challenges in Metallurgical Valve Applications
Metallurgical processes demand valves that can withstand:
High temperatures from 400°C to over 1,200°C
Abrasive particles, including dust, slag, and scale
Thermal cycling, causing expansion and stress
Corrosive gases and liquids, such as SO₂, CO, H₂S, and acids
High-pressure steam, hot air, and molten metal flow
Using standard cast iron or carbon steel valves often results in premature failure. Material upgrades are essential to ensure long-term reliability and safety.
Recommended Valve Materials by Application
Below are common metallurgical applications and Yuanda's suggested valve materials:
| Application | Recommended Valve Materials from Yuanda |
|---|---|
| Blast furnace gas valves | Cast steel (WCB, WC6) body with hard-faced trim (e.g. Stellite); optional pressure seal bonnet design |
| Hot blast stove valves | WC9 or heat-resistant alloy with graphite packing and metal seats |
| Ash and slag discharge valves | Ni-Hard castings, ceramic-lined gates, or high-chrome alloy for erosion resistance |
| Acid gas and flue gas valves | CF8M/316L stainless steel or Duplex SS; PTFE or graphite seals |
| Oxygen control valves | 316L stainless steel, clean design, with anti-spark trims |
| Pickling system valves | Alloy 20, Hastelloy, and PTFE-lined ball valves for strong acid environments |
| High-temp steam valves | C12A, Cr-Mo alloy or Inconel, pressure seal bonnet, metal seated design |
All these configurations are available across Yuanda’s product lines, including:
