Introduction
254SMO is a high-performance super austenitic stainless steel that combines excellent impact toughness, resistance to chloride-induced stress corrosion cracking, and outstanding resistance to pitting and crevice corrosion. Its strength is approximately twice that of 300 series stainless steels.
In certain applications, 254SMO serves as an economical alternative to high-nickel alloys and titanium alloys. The material also exhibits favorable machinability and formability.
The following sections provide a detailed examination of 254SMO stainless steel.
Examples of applications :
• Petroleum production
• Saltwater handling
• Pulp mill bleach systems
• Tall oil distillation columns
• Desalination equipment
• Food and chemical processing equipment
• Flue gas desulphurization scrubbers
• Offshore oil & gas production equipment
