Stainless Steel SMO 254 Circles

SMO 254, also known as UNS S31254, is a super-austenitic stainless steel used for corrosive atmosphere. It is a stainless steel of the austenitic class that contains a high amount of chromium, molybdenum, and nitrogen, thus making it resistant to pitting, crevice corrosion, and general corrosion. SMO 254 circles are precision-machined parts used in various industries where strength and corrosion resistance are desirable.

Mechanical Properties of SS SMO 254 Circles

The table below serves as a valuable reference point for understanding the performance characteristics of the SMO 254 circles.

Thus, one can assess the circles's structural integrity and suitability for demanding industrial applications.

Advantages of SMO 254 Circles

These flexible circles offer numerous benefits for various industrial applications.

• High Strength: The alloy also possesses good tensile and yield strength. This makes the alloy suitable for structural applications where strength and ductility are desirable.
• Good Weldability: TIG and MIG welding can be used for welding SMO 254, but certain measures should be taken to prevent the material from getting sensitised.
• Chloride Stress Corrosion Cracking (SCC): SMO 254 Circle also has a very good resistance to chloride-induced stress corrosion cracking, making the alloy suitable for use where this type of corrosion is expected.
• Excellent Formability: It has good formability and is easy to machine; this means that it is possible to come up with intricate shapes and parts.

SMO 254 Circle offers several advantages that make it suitable for industrial and commercial applications.
