SS 904L Fittings are manufactured at Navgraha Steel & Engg Company. We offer Fittings with several components of various sizes and dimensions and differ with standards, pressure classes, and specifications. It is easy to choose required components among types such as concentric and eccentric reducers, various shapes and sizes of nuts and bolts, pipe caps, Nipple, elbow, and bend of several types. In addition, it tends to be excellent resistant to corrosion in acids and seawater.
These Fittings are widely accepted for:
• Superior endurance to corrosion
• Outstanding mechanical properties
• Excellent weldability
• Higher toughness
It also tends to have outstanding chemical properties. Our Fittings are durable due to their rigid structure and capability to withstand several corrosive environments. Fittings are used to connect pipes or tubes in piping systems to regulate fluid flow. These fittings are offered in Seamless, Welded type and also available as Fabricated one.
• Why SS 904L is the best choice?
SS 904L is a non-stabilized low carbon Stainless Steel grade with an austenitic structure. It is known as high alloy steel, where copper addition enhances resistance to acid decay. It is highly pure low sulfur steel containing Chromium with expensive elements Nickel and Molybdenum. UNS NO8904 is another name for SS 904L that enhances inter-crystalline corrosion resistance due to low carbon.
• Functions of SS 904L Fittings:
These fittings are purposed for high-pressure conditions in piping systems. These are thicker to sustain pressure and formed with a smooth finish. It is prevented from chloride attacks and brine temperature with excellent resistance. It is applied in harsh corrosive media and prevents corrosion by reducing phosphoric acid, sulphuric acids, and acetic acids. These are therefore used in fertilizer and acid production, utility scrubber assemblies.
• UNS NO8904 Fittings:
These fittings are leak- preventing, and excellent toughness is demonstrated. Our fittings are long-lasting, flexible, and easily formable due to low carbon. It prevents atmospheric corrosion and pitting and reveals excellent resistance to stress and crevice cracking. It is applied in intermediate temperatures with excellent oxidation prevention.
Applications of SS 904L/UNS NO8904 Fittings:
• Sea Water Equipments
• Heat Exchangers
• Pulp, Condensers
• Chemical and Gas Processing
