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 steelsgood 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:Ni:17.5~18.5 Cr:19.5~20.5 Mo:6~6.5 Cu:0.5~1.0 N:0.18~0.22 C:Max0.20 Mn:Max1.0 Si:Max0.8 P:Max0.03 S:Max0.01
The speification we produce: 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.
