Alloy 254 also known as 254 SMO alloy, 6Mo alloy, 6 Moly alloy, or 254 SMO Super Austenitic Stainless Steel alloy. 254 SMO alloy is intentionally designed with high molybdenum content in its chemical composition, to achieve exclusive properties like impact toughness, resistance towards pitting corrosion, fatigue corrosion and crevice corrosion, and chloride stress cracking. 6 Mo alloy is also twice as strong as rest of 300 series stainless steels. Hence 6 Moly alloy is highly in demand for applications demanding good strength and impact toughness, resistance towards corrosive and oxidation medias and use under extreme temperatures.

Exclusive characteristics of 254 SMO Tubes (6 Mo Tubes or 6 Moly Tubes) make them highly applicable in applications like marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.
Generally 254 SMO Tubes are applicable in saltwater handling, petroleum production, pulp mill bleach systems, flue gas desulphurization scrubbers, food and chemical processing equipments, offshore oil and gas production equipments, tall oil distillation columns, desalination equipments.
Since 254 SMO Welded Tubes are applicable in severe corrosive environments, their welding process should be done under clean and careful conditions to ensure the retention of corrosion characteristics of weld metal and heat affected zones. No subsequent heat treatment is required if welding is done without preheating. Manual metal-arc welding with covered electrodes and gas-shielded arc welding, mainly by means of the TIG and MIG methods are some suitable methods of fusion welding.

254 SMO Seamless Tube
A solid round billet of 254 SMO alloy is heated at certain temperature and pushed with pressure over a sharp piercing object to form a cylindrical hollow tube spread across the longitudinal stretch. The tube formed through this process is known as 254 SMO Seamless Tubes which consist of no weld or seam or any joints, as a result these 6Mo Seamless Tubes have higher load bearing capacity and high stress capacity. 6Moly Seamless Tubes do not have any weld throughout its length along its cross-section. Due to its making process, SMO 254 Seamless Tubes exhibits excellent roundness and ovality as compared to its welded counterpart.
Oshwin Overseas are leading 254 SMO Seamless Tubes Exporters all over globe. We are specialized 254 SMO Seamless Tubes Manufacturers and 254 SMO Seamless Tubes Suppliers.

254 SMO Welded Pipe
A flat strip or sheet or plate of 254 SMO alloy is pressurized into desired cylindrical hollow tube spread across the longitudinal stretch. This tube is then pressed again for the either ends of sheet to meet and welded together using high energy welding source like an electric arc, laser beam, plasma arc, electron beam etc. Then is it allowed to cool and solidify, thereby forming a 254 SMO Welding Tube. This 6Mo Welded Tubes contains weld or seam or joint, and hence are cheaper than its counterpart Seamless Tubes and hence more in demand and reaily available. The wall thickness of 6Moly Welded Tubes is more consistent than its counterpart. Inner surface of SMO 254 Welded Tubes can be checked and cleaned before manufacturing then, which is not possible in seamless tubes.
