254 SMO(UNS S31254,EN 1.4547) is an austenitic stainless steel of the ELC type developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties:
1.excellent resistance to pitting and crevice corrosion
2.high resistance to general corrosion
3.high resistance to stress corrosion cracking
4.higher strength than conventional austenitic stainless steels
good weldability
Lord Steel Industry Company Limited is Known as the most professional and reputable supplier and manufacturer of such material(UNS S31254) in Asia.
We start to develop such material since 2001 and export to most of the countries worldwide, including Germany, Belgium,Holland,Argentina,Venezura,USA,etc.
Alloy254SMO Chemical Composition:

Seamless Tube: OD:15.88~219.1mm WT:0.8~20mm
Standard: ASTM A269, A213,A312,EN216-3.
Metallurgical structure Alloy 254SMO is face-centered cubic lattice structure. In order to obtain austenitic structure, 254SMO general annealing in the 1150-1200degree.In some cases, the material maybe with the 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 600-1000degree, they may phase in the grain boundary precipitation.
We Look forward to your enquiry of such material and business relationship between us soon.
Many Solutions, One Decision Here.
Applied fieldï¼ÂÂ254SMO 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.
