Our duplex stainless steel threaded rods and nuts meet DIN933 and GOST33259 specifications, providing unparalleled durability for flange connections. Designed for extreme environments, they combine corrosion resistance and high tensile strength at a very competitive price. Global customers benefit from tailor-made solutions and reliable supply chain partnerships.
The stainless steel Threaded Rod series is a cornerstone solution for flange connection fixing in the petrochemical, marine and heavy machinery industries. It is designed to withstand extreme pressure fluctuations and temperature changes, and maintain structural integrity in environments where inferior fasteners may fail. Standardized thread patterns ensure seamless compatibility with international flange systems, and the duplex steel composition has inherent resistance to stress corrosion cracking.
Precision manufacturing processes ensure consistent dimensional accuracy throughout production batches. Advanced cold forming techniques increase surface hardness without affecting the core ductility of the material, creating fasteners that can absorb vibration stress better than traditional fasteners. Satin surface treatment minimizes wear during installation and maintains sufficient friction coefficient to prevent accidental loosening under dynamic loads. The combination of controlled manufacturing parameters and material science ensures reliable operation in bridge construction, pipeline networks and power generation infrastructure.
The stainless steel Threaded Rod series uses a strategic alloy formulation that mixes chromium, molybdenum and nitrogen in a balanced ratio to achieve optimal performance. The chemical composition has excellent pitting resistance equivalent ratings and maintains a yield strength of more than 550 MPa. Unlike standard stainless steels, the duplex structure exhibits higher fatigue resistance under cyclic loading conditions, which is particularly suitable for wind turbine foundations and seismic retrofit applications. The inherent non-magnetic property further broadens the application in specialized electrical and medical equipment installations.
Comprehensive quality assurance protocols verify each batch of threaded rod through rigorous mechanical testing and surface inspection. Third-party certification ensures compliance with DIN933 dimensional standards and GOST33259 performance requirements. An automated sorting system ensures length tolerances are accurate to within ±0.5 mm, and the thread rolling process maintains pitch accuracy within ±2°. Manufacturing controls eliminate installation challenges caused by dimensional inconsistencies and can significantly reduce assembly time on large projects.
