254 SMO Tubing

254 SMO Tubing

Supplier of ASME SA213 werkstoff nr. 1.4547 EFW / annealed and cold drawn tube. We specialize in Alloy 254 High Pressure Tube

Highly alloyed metals have superior mechanical qualities and greatly increased corrosion resistance, especially when compared to more conventional stainless steel alloys. The 254 SMO Tube, which is thought to be a highly alloyed metal, has one of the best PREN values of any austenitic stainless steel. Few alloys can provide the property of resistance to pitting. The PREN Value of the A213 UNS S31254 Seamless Tube, which is larger than 42.5, is particularly high. Any stainless steel with a PREN rating greater than 38 is regarded as having exceptional resistance to pitting corrosion.

Comparing Alloy 254 High Pressure Tube to a number of conventional austenitic stainless steel alloys, it also demonstrates strength to a far greater extent. Din 1.4547 Welded Tubes have excellent weldability because the carbon concentration is less than 0.020 percent. Most stainless steels with higher carbon and chromium content in their alloy have a tendency to develop carbide precipitates, which could eventually cause the material to deteriorate through intergranular corrosion. So, although having a higher chromium level, the Sandvik 254 smo tube alloy minimises intergranular corrosion thanks to its reduced carbon content.

The Type 254 ERW Tubes and other types of equipment used in oil fields are exposed to sulphur. As a highly corrosive residual element, sulphur causes pipe cracking as it builds up over time. The 6mo EFW Tubing is sulfur-resistant. Thus, the use of tubo smo 254 avoids the occurrence of corrosion cracking caused by sulphide stress in many oilfields.
