Leading Stainless Steel 310H Flanges Manufacturer & Supplier in the USA – Nakoda Steel Industry
Nakoda Steel Industry is a recognized Stainless Steel 310H Flanges Manufacturer and Supplier in the USA, offering top-quality flanges for high-temperature and corrosive applications. Engineered with a higher carbon content, 310H stainless steel is ideal for elevated temperature services, including petrochemical, fertilizer, refinery, and power generation plants across the United States.
Why Choose Stainless Steel 310H Flanges?
Stainless Steel 310H (UNS S31009) is a high-carbon version of 310, offering superior strength at high temperatures. It is commonly used in industries requiring strong oxidation resistance and thermal stability.
- 310H Slip-On Flanges – Excellent for high-heat environments and easy to install with welding.
- 310H Threaded Flanges – Ideal for low-pressure, non-welded piping applications.
- UNS S31009 Weld Neck Flanges – Designed for high-stress applications, these flanges offer strength and leak-proof connections.
- 310H Blind Flanges – Perfect for isolating piping systems or terminating pipe ends under pressure.
- 310H Socket Weld Flanges – Recommended for smaller pipe diameters with strong weld integrity.
High-Temperature & Corrosion Resistance
Our Stainless Steel 310H Pipe Flanges offer exceptional performance in oxidizing and carburizing environments. These flanges resist:
- Smoldering nitric acid at room temperature
- Fused nitrates up to 425°C (797°F)
- Seawater corrosion (similar to 316 grade) up to 22°C (71.6°F)
Due to their higher carbon content, 310H flanges may be prone to intergranular corrosion after welding or high-temperature exposure. To mitigate this, we also offer Double Certified Flanges for added versatility in demanding U.S. industrial applications.
SS 310H Flanges Variants Available:
- 310H Lap Joint Flanges
- 310H Spectacle Blind Flanges
- 310H Ring Type Joint (RTJ) Flanges
- 310H Spacer Flanges
- ANSI B16.5 F310H Nippolet & Forged Flanges
- 150# to 2500# ANSI Class Flanges
Our flanges are widely used in U.S. industries such as oil & gas, chemical processing, refineries, and heat exchangers, particularly in states like Texas, Louisiana, California, and Pennsylvania.
