Best Price for Incoloy 800 - Stainless Steel 254SMO-F44 – Sekonic

Common Trade Names: 254Mo, F44, UNS 31254 , W.Nr 1.4547

Alloy F44(254Mo) with high concentration of molybdenum,chromium and nitrogen,this steel  has very good resistance to pitting and crevice corrosion performance. Copper improved corrosion resistance in some of the acid . In addition, due to its high content of nickel,chromium and molybdenum, so that 254SMO have a good stress strength corrosion cracking performance

Why 254SMo (F44) ?

• A lot of a wide range use of experience has shown that even iin higher temperatures, 254SMO in the sea water is also highly resistant to corrosion performance gap, only a few types of stainless steel with this performance.
• 254SMO such as bleach paper required for the production of acidic solution and the solution halide oxidative corrosion resistance and corrosion resistance can be compared to the most resilient in the base alloy of nickel and titanium alloys.
• 254SMO due to a high nitrogen content, so its mechanical strength than other types of austenitic stainless steel is higher. In addition, 254SMO also highly scalable and impact strength and good weldability.
• 254SMO with high molybdenum content can make it higher rate of oxidation in the annealing , which after the acid cleaning with rough surface than normal stainless steel is more common than the rough surface. However,has not adversely affected for the corrosion resistance of this steel .

254SMo (F44) Application field：

254SMO is a mult-purpose material can be used in many industrial applications:
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.
