Gayatri tubes, we are the best manufacturer as well as suppliers of all types of fittings with all grades. We are also exporter and wholesaler of SMO 254 Forged Fittings with different forms and shapes and sizes. We manufacture forged fitting in various dimensions, diameters, thicknesses, and lengths. We used highly specifications and international standard in manufacturing our product. Alloy SMO 254 is austenitic steel with the addition of many chemical contents like nitrogen, molybdenum and low amount of carbon. Alloy SMO 254 is stronger than other austenitic grades and shows strengths twice rather than stainless steel 300 grade. This grade is known for its excellent features such as resistance to corrosion fatigue, crevice stress cracking corrosion, uniform corrosion, pitting corrosion; this grade has high ductility and strength. Because of the high amount of chromium, nitrogen, and molybdenum, grade 254 is commonly used in chloride environments like seawater, pulp mill bleach plant, pollutant water, and other process stream. This grade is used in many applications like desalination equipment, petroleum production, flue gas scrubber, saltwater handling.
SMO UNS S31254 Socket weld Forged Fittings have different types like threaded, welded, elbow, lateral, union, tees, cross, etc. SMO 254 Forged Threaded Fittings is nonmagnetic and it doesn’t have electrical and thermal conductivity. The SMO 254 Forged fitting elbow Fittings is widely used for its good resistance to crevice and pitting corrosion in containing environment. The forged threaded tee types fitting have high toughness and high strength with high resistance property rather than grade 300. The socket weld elbow forged fitting has good yield strength and tensile strength and high impact toughness as well.
The application of SMO 1.4547 Forged Fittings are- power generation, gas processing, pharmaceuticals, chemical equipment and process, pulp and paper industry, petrochemical industry, seawater application, marine industry, etc. This type of fitting is also used in food processing, heat exchanger, offshore and oil drilling company, condenser, shipbuilding, chemical industry, and many more. We perform different types of tests during manufacture to check the quality of the product such as chemical test, impact test, destructive and nondestructive test, flaring test, eddy current test, mechanical test, strength test, hardness test, toughness test, etc.
