254SMO (UNS S31254)  

 254SMO austenitic stainless  steel plate, sheet, strip, pipe, tube(UNS S31254)           

Introduction

254SMO is an austenitic stainless  steel, similar to alloy 904L, but with increased molybdenum and nitrogen  contents, to be used in seawater, oil and gas piping systems on offshore  production platforms and other aggressive chloride bearing media. With an  excellent resistant to pitting, crevice corrosion and to stress-corrosion  cracking.               

Characters

l    Excellent resistance to pitting and crevice corrosion

l    High resistance to general corrosion

l    High resistance to stress corrosion cracking

l    Higher strength than conventional austenitic stainless  steels

l    Good weldability

Applications of 254smo

l    Seawater handling equipment

l    Pulp mill bleach systems

l    Tall oil distillation columns and equipment

l    Chemical processing equipment

l    Food processing equipment

l    Desalination equipment

l    Flue gas desulfurization scrubbers

l    Oil and Gas production equipment
