254SMO equal grades: UNS S31254, F44

Design features of 254SMO:
*High resistance to pitting and crevice corrosion
*Very high resistance to chloride stress corrosion cracking
*50% stronger than 300-series austenitic stainless steels
*Excellent impact toughness
*Excellent workability and weldability

Applications of 254SMO: 
Seawater handling equipment
Pulp mill bleach systems
Tall oil distillation columns and equipment
Chemical processing equipment
Food processing equipment
Desalination equipment
Flue gas desulfurization scrubbers
Oil and gas production equipment

General characteristics of 254SMO: 
254SMO is an austenitic stainless steel designed for maximum resistance to pitting and crevice corrosion. With high levels of chromium, molybdenum, and nitrogen, 254SMO is especially suited for high-chloride environments such as brackish water, seawater, pulp mill bleach plants, and other high-chloride process streams. 254SMO offers chloride resistance superior to that of alloy 904l, alloy 20, alloy 825

254SMO is compatible with the common austenitic stainless steels
It is often used as a replacement in critical components of larger constructions where type 316l or 317l has failed by pitting, crevice attack, or chloride stress corrosion cracking
