Product Description

254SMo hex bolt/ 1.4547 bolt/UNS S31254 DIN931 half thread hex head bolt in stainless steel fasteners
The high concentration of molybdenum,chromium and nitrogen made 254SMO 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.

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
