PRODUCTS SPECIFICATION

 254SMO Stainless Steel Pipe Tube UNS S31254 Stainless Tube SCH40 SCH80

ASME SA 213 ASTM A213 ASTM A269 S31254 254 SMo EN 10216-5 1.4547 Alloy 6Mo X1CrNiMoCuN20-18-7 Tubing is an superaustenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. With high levels of chromium, molybdenum, and nitrogen, 254SMo is especially suited for high chloride environments such as brackish water seawater pulp mill bleach plants and other high chloride process streams. 254SMo Pipe offer chloride resistance superior to that of Alloy 904L, Alloy 20, Alloy 825 and Alloy G. Copper improved corrosion resistance in some of the acid . In addition, due to its high content of nickel,chromium and molybdenum, so that 254SMo S31254 Tubing has a good stress corrosion cracking performance.

 

254 SMo S31254 Tubing is compatible with the common austenitic stainless steels. In new construction, 254SMo has been found in many cases to be a technically adequate and much less costly substitute for nickel based alloys and titanium. 254SMo is substantially stronger than the common austenitic grade, also characterized by high ductility and impact strength. 254SMo is readily fabricated and welded.

254 SMo S31254 Tubing is face-centered cubic lattice structure. In order to obtain austenitic structure, 254 SMo S31254 Tubing general annealing in the 1150-1200°C. In some cases, the material may have traces of metal middle phase (χ phase and α-phase). However,their impact strength and corrosion resistance are not adversely affected in normal circumstances. When placed in the range of 600-1000°C, they may phase in the grain boundary precipitation.

PRODUCTS APPLICATION

254 SMO S31254 Tubing S31254 Tubing Application

The most corrosion resistant stainless steel contains 6% to 7.3% Mo. Such as 254SMo alloy steel are used as power plant condensers, subsea pipelines, and key components of nuclear power plants, such as industrial water pipelines.

• 1. Petroleum, petrochemical equipment, petro-chemical equipment, such as the bellows.
• 2. Pulp and paper bleaching equipment, such as pulp cooking, bleaching, washing filters used in the barrel and cylinder pressure rollers, and so on.
• 3. Power plant flue gas desulphurization equipment, the use of the main parts: the absorption tower, flue and stopping plate, internal part,spray system.
• 4. At sea or sea water processing system, such as power plants using sea water to cool the thin-walled Condenser, desalination of sea water processing equipment,can be applied even though the water may not flow in the device.
• 5. Desalination industries, such as salt or desalination equipment.
• 6. Heat exchanger, in particular in the working environment of chloride ion.
• 7. Hydraulic Tubing and instrumention tubing
• 8. Tanks and pipelines for chemicals with high halide contents
