What is 254 SMO Plate?

254 SMO Plate is a corrosion-resistant alloy plate designed specifically for seawater and other chloride environments. It combines excellent formability and weldability with superior resistance to stress corrosion cracking. The combination makes it an ideal material choice for seawater desalination, marine engineering, heat exchangers, pumps, valves and storage tanks. It’s often polished to remove any surface imperfections, which provides a smooth finish that reduces maintenance costs while providing superior protection against the elements. This type of plating is also known for its durability – making it resistant to wear and tear even in highly corrosive environments like salt water or acidic compounds. In short, 254 SMO Plates are the perfect material choice for long-term solutions that require reliable performance in harsh conditions!

Properties of 254 SMO Plate

254 SMO (6% molybdenum, 7% nickel) is a highly alloyed austenitic stainless steel with excellent corrosion resistance in various aggressive environments. It has superior chloride pitting and crevice corrosion resistance to other austenitic stainless steels. Its good weldability and formability characteristics make it extremely versatile in many applications. Unique properties of 254 SMO plate include outstanding formability and weldability, good strength-to-weight ratio, excellent workability after heat treatment or welding, superior fire and creep strength when exposed to very high temperatures, non-magnetic nature even at elevated temperatures, as well as good fatigue endurance limit.

254 SMO Plate Specifications

254 SMO Plate is a 300 series austenitic stainless steel grade variant. It has an improved corrosion resistance compared to other grades in its range due to the addition of copper and molybdenum, with a relatively high chromium content (25%). The plate can withstand temperatures up to 870°C (1600°F) and has excellent strength at both low- and high-temperature extremes, as well as good weldability, formability, work hardening rate, toughness, resistance to chloride pitting and crevice corrosion. It also offers superior stress rupture properties compared to 304-grade stainless steel plates making it suitable for tough environments.

Applications of 254 SMO Plate

254 SMO, or 6% Mo stainless steel plate, is commonly used in many industries because of its significant mechanical properties and good corrosion resistance. It is cost-effective compared to other grades. Some primary applications include marine and food production machinery components, piping systems for seawater and wastewater services, chemical process equipment, pharmaceutical tanks, heat exchangers for evaporators and refrigeration systems, valves, and pumps. It is also widely used in architecture due to its superior appearance and excellent welding characteristics.

Choosing the Right 254 SMO Plate Supplier

Finding the right supplier for 254 SMO plates is critical for ensuring the quality and reliability of the material. When choosing a supplier, look for one that can provide the material specifications you need, along with excellent customer service and support. Be sure to ask about lead times and delivery options to meet your project timelines.


In conclusion, the 254 SMO plate is an excellent choice for applications requiring strength, durability, and corrosion resistance. Its high levels of molybdenum, chromium, and nickel offer superior performance in harsh industrial environments. By understanding the properties, specifications, and applications of 254 SMO plates, you can make an informed decision when selecting this super austenitic stainless steel material for your project.
