Stainless Steel Alloy 254

Alloy 254. which is also found under the brand name Sandvik 254 SMO and UNS S31254. is super austenitic stainless steel that is well known for its outstanding resistance to pitting, crevice corrosion, stress cracking, and fatigue corrosion. One reason for these unique properties is Alloy 254’s specific chemical makeup which includes:

• Fe (remainder)
• Cr 19.5-20.5%
• Ni 17.5-18.5%
• Mo 6-6.5%
• Mn 1.0% max
• Si 0.8% max
• P 0.03% max
• C 0.02% max

Because of its high levels of chromium, nitrogen, and molybdenum, Alloy 254 is stronger than most austenitic grade stainless steel and nearly twice as strong as 300 series stainless steel. It is perfect for use in a number of different applications including:

• Chemical processing
• Saltwater applications like shipbuilding, marine products, and desalination
• Oil and gas
• Power generation
• Pulp and Paper
