Product Description

**4 SMO(UNS S****4,EN 1.***7)Seamless stainless steel pipe

**4 SMO(UNS S****4,EN 1.***7) 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 S****4) in Asia.We start to develop such material since ***1 and export to most of the countries worldwide, including Germany,Belgium,Holland,Argentina,Venezura,USA,etc.

Metallurgical structure Alloy **4SMO is face-centered cubic lattice structure. In order to obtain austenitic structure, **4SMO general annealing in the ********0degree.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 *******0degree, they may phase in the grain boundary precipitation.

We Look forward to your enquiry of such material and business relationship between us soon.
