Top Manufacturer & Exporter of Stainless Steel 316/316L Flanges in the USA – Nakoda Steel Industry
Nakoda Steel Industry is a trusted manufacturer and global exporter of Stainless Steel 316 and 316L Flanges, supplying premium-grade products to clients across the United States. Known for superior corrosion resistance and excellent fabrication qualities, our SS 316/316L pipe flanges are widely used in chemical processing, food manufacturing, and pharmaceutical industries throughout the U.S.
Why Choose Stainless Steel 316/316L Flanges?
Stainless Steel 316/316L Flanges offer enhanced corrosion resistance in both acidic and chloride-rich environments, making them ideal for industrial applications across the U.S., especially in coastal and chemical-prone regions such as Texas, California, Florida, and Louisiana.
- 316 Slip-On Flanges: Excellent for general-purpose usage, offering easy installation and reliable sealing.
- 316L Threaded Flanges: Ideal for low-pressure applications, especially where welding isn’t suitable.
- 316 Weld Neck Flanges: Designed for high-pressure piping systems in petrochemical and refinery operations.
- 316L Blind Flanges: Used to isolate piping systems and terminate flow in a secure, corrosion-resistant way.
- 316 Socket Weld Flanges: Provide strong, leak-proof connections for critical service pipelines in the U.S. energy sector.
Exceptional Performance Across U.S. Industries
Our Stainless Steel 316 and 316L Flanges offer superior performance in:
- Boiling 20% phosphoric acid environments
- Hot organic and fatty acid handling in food and pharma facilities
- Freshwater systems with high chloride levels
- Aggressive environments prone to intergranular corrosion
Thanks to the low carbon content, 316L flanges are specifically preferred in weld-affected zones, ensuring longer life and better resistance to corrosion post-fabrication.
High Workability & Durability
- Hot forming temperature: 1700°F to 2200°F (927°C to 1204°C)
- Cold working improves strength and hardness
- Easily fabricated with standard U.S. shop practices
Flanges like the 316L Lap Joint and Spectacle Blind Flanges are ductile and formable, though prone to work hardening. Cold-formed components may develop mild magnetism but maintain mechanical integrity.
