UNS S31254 is high in both chromium and molybdenum content, which endow this stainless steel with excellent pitting corrosion and crevice corrosion resistance in high-chlorine environments. Its high nickel content also provides exceptional stress corrosion cracking resistance.
UNS S31254 is an austenitic stainless steel, the same sort of heat treatment may be used. In general, we suggest that UNS S31254 be water cooled with a solution treatment between 1125 and 1175 ℃.
Pickling
A mixture of nitric and hydrofluoric acids is used in pickling. To the extent that UNS S31254 is more resistant to corrosion than SUS 304, descaling is more difficult. Alkaline immersion for a short time before acid pickling and shot blasting if possible are effective at descaling.
UNS S31254 is widely used in Petroleum production
Saltwater handling
Food and chemical processing equipment
Pulp mill bleach systems
Flue gas desulphurization scrubbers
Tall oil distillation columns
Offshore oil & gas production equipment
Desalination equipment
