At Leoscor Alloy Pipes, we supply 254 SMO Pipes for applications where standard stainless steel grades may not provide the required durability. These pipes are widely used in chemical processing plants, marine and offshore industries, seawater systems, desalination facilities, pulp and paper mills, heat exchangers, and high-pressure piping systems.
What are 254 SMO Pipes?
254 SMO Pipes, also known as UNS S31254 Pipes, are high-alloy austenitic stainless steel pipes developed for superior corrosion resistance in harsh environments. The grade is known for its excellent performance in chloride-rich, acidic, and seawater applications.
The advanced composition of 254 SMO stainless steel, containing high levels of chromium, molybdenum, and nitrogen, enhances its resistance to pitting, crevice corrosion, and stress corrosion cracking. Due to its high molybdenum content, this material is also commonly referred to as 6Mo stainless steel.
Leoscor Alloy Pipes supplies 254 SMO Pipes manufactured according to industry standards, including ASTM A312 UNS S31254 for pressure piping applications and ASTM A269 UNS S31254 for tubing requirements. These pipes are available in different sizes, specifications, and finishes to meet the needs of various industrial sectors.
With excellent mechanical properties and superior corrosion resistance, 254 SMO Pipes from Leoscor Alloy Pipes are an ideal choice for critical applications requiring high performance, reliability, and long-term service in challenging environments.

Where 254 SMO fits against 316L, 317L and duplex
Buyers often reach for 254 SMO by default once 316L has failed once. It is usually the right call, but not always the cheapest one that will work.
| Grade | PREN (approx.) | Pick it when |
|---|---|---|
| 316L | 24 to 26 | Mild chlorides, general chemical service. Starting point for most plant piping. |
| 317L | 29 to 31 | 316L is corroding faster than expected. One step up, still austenitic, easier to weld than 254 SMO. |
| 254 SMO (this page) | 42 to 44 | Seawater, brine concentrators, bleach plants — where 317L is still not enough. |
| Super Duplex 2507 | 42 to 44 | Same PREN territory as 254 SMO, but roughly double the yield strength — worth comparing when wall thickness or pressure rating matters as much as corrosion resistance. |
254 SMO and super duplex land at a similar PREN, so the deciding factor is often mechanical: 254 SMO is easier to weld and behaves like a standard austenitic pipe on site, while super duplex gives you a lighter wall for the same pressure class. Tell us your pressure rating and fabrication constraints and we will recommend the more economical fit.
