Nakoda Steel Industry – Premier Global Manufacturer and Supplier of High-Performance Stainless Steel 304 Flanges for Demanding Industrial Applications Across the world specifically United States and United Kingdom
As a distinguished leader in precision-engineered piping solutions, Nakoda Steel Industry stands at the forefront of stainless steel flange manufacturing, supplying superior quality ASTM A182/ASME SA182 certified Stainless Steel 304 flanges to major industrial sectors throughout North America and Europe.
Our comprehensive range of austenitic stainless steel pipe flanges, enhanced with optimal nickel content, delivers exceptional performance in both cryogenic and elevated temperature environments, making them the preferred choice for engineers and procurement specialists in the petroleum, chemical processing, and power generation industries.
Unmatched Material Properties and Technical Advantages:
Advanced Metallurgical Composition: Our SS 304 flanges contain 18-20% chromium and 8-10.5% nickel with controlled carbon content below 0.08%, ensuring superior intergranular corrosion resistance particularly crucial for welded assemblies in offshore and coastal installations
Enhanced Mechanical Characteristics: Minimum tensile strength of 515 MPa (75 ksi) and yield strength of 205 MPa (30 ksi) guarantee reliable performance in high-pressure piping systems common in US refineries and UK processing plants
Exceptional Corrosion Resistance: Demonstrated performance in harsh environments including chloride-rich atmospheres, acidic media, and alkaline solutions prevalent in chemical processing facilities
Temperature Versatility: Maintains structural integrity across an extensive operational range from -425°F (-254°C) to 1,600°F (871°C), suitable for both cryogenic storage and high-temperature steam applications
