We at Navgraha Steel & Engg Company fabricate flanges of grade SS 321. SS 321 Flanges are excellent quality stainless steel flanges presenting the large scope of applications in the piping system. It connects pipes or tubes, allowing fluids to flow through them. These are widely accepted in several sectors to direct and control the flow of gas or liquid conduction. Flanges are typically differentiated as lap-joint, ring-joint, socket weld and orifice and so on. These SS 321 Flanges are connected to different joints includes flat or raise faces, threaded, welded type joints. It is largely formed with the inclusion of standard sizes as well as we provide custom-size flanges. These flanges are pitting resistant and defend against chloride corrosion. Its excellent resisting property is advantageous in ambient heat clean water that surrounds chlorides.
SS 321 Flanges are pressure susceptible, including low as well as high pressures. These ranges are defined with different classes, and temperature ratings of the flanges are also described. Furthermore, it shows exceptional resistance and efficient working in marine surroundings. Higher strength is modified with high-temperature corrosion resistance. It purposes low and high-level thermal applications in addition to non-magnetic appearance. Crevice corrosion is opposed with excellent resistance to moist chloride surroundings improving wet deterioration properties.
What is SS 321 Characteristics?
• Austenitic Steel
• Stabilized with Higher Strength
• Excellent Aqueous Corrosion Proof
• Excellent Pitting Protection
Properties of SS 321 Flanges:
• Excellent Strength
• Wide Thermal Range
• Higher Temperature Susceptible
• Hardness
Where are SS 321 Flanges proposed?
• Marine
• Chemical Industry
• Food Process
• Oil and Gas
• Waste treatment
• Water Supply
• Offshore and Onshore
SS 321 Flanges provides stress corrosion cracking protection bearing loads. Also, it is featured as leak-protected and easily mounting flanges. Its durability and enhanced strength is gained with stabilized austenitic structure. In addition, it shows excellent tensile property suitable for higher loads systems. The low thermal expansion provides the high-temperature capability to these flanges. It reveals superior opposition to corrosion in Fresh Water, Organic Solvents, and excellent resistance to the reduction in Alkalis and Acid surroundings. Thus it is recommended for chemical processing applications.
