What are 254 SMO Pipes & Tubes?
Designed to outperform standard grades, SMO 254 also known as UNS S312 is a hyper austenitic stainless steel Its great molybdenum concentration about 6% sets it apart from other materials since it increases their resistance to corrosion, most especially against chlorides and other harmful substances. Being resistant to localised corrosion, it is ideal for heavy-duty industrial applications. Its exceptional tensile strength, high ductility, and strong impact resistance make it also a perfect material for such purposes.
