Special materials: systems and equipment in Super Duplex Steel 1.4410 and hybrids

In the continuous search for Quality characterizing Masterinox products, we partly direct our attention to raw materials research, in order to identify the most suitable materials to meet customers’ needs and optimize the lifetime of our equipment.

In the course of our experience and research we have often worked with special steels, including Super Duplex 1.4410, an austenitic-ferritic stainless steel alloy, showing excellent resistance to corrosion in general, to stress corrosion cracking, fatigue corrosion, pitting, crevice corrosion and erosion-corrosion, also featuring a high mechanical strength.

When it is necessary to use multiple alloys on the same equipment, Masterinox is able to offer a long experience and know-how in order to ensure correct execution of the piece. After several metallurgical studies, we are able to build hybrid equipment in order to offer machines with a greater corrosion resistance than the main competitors on the market. Furthermore, our knowledge of materials allows us to build increasingly safe equipment with high safety standards.

Super Duplex is the ideal choice for environments where extreme corrosion resistance is required while maintaining a low cost.Among the main applications:

  • Environments containing chloride as processing systems (e.g. oil and gas exploration and production)
  • Refining, petrochemical and gas processing plants with high use of chlorides
  • Situations with a high mechanical load in seawater and other environments containing chlorides
  • Pulp and paper production
  • Chemical industries using seawater cooling systems
  • Salt evaporation and desalination plants
  • Geothermal wells

At Masterinox we have been working this material for many years. Both in the welding phases and in the non-destructive tests, we use the most modern technologies in the sector, in this way we can keep the integrity of the raw material and take full advantage of its features.

Here is a recent example of a product made with Super Duplex Steel:
