EFW 2507 super duplex stainless steel,Round Mechanical Tubing UNS S32750 A928M​

Characteristics:

Grade 2507 is a Molybdenum and Nitrogen alloyed Super-Duplex stainless steel with corrosion resistance
in-line with the 6 Mo grades (e.g. 254 SMO®), and with a yield strength more than double that of austenitic stainless steels. It is also the strongest Duplex in welded tubular products.

Characteristic properties:

• High mechanical strength

• Good weldability

• Good corrosion resistance

• High resistance to Stress Corrosion Cracking (SCC)

• Good machinability

• Very good wear and abrasive resistance

• Low thermal expansion

• Good fatigue properties

• Temperature range -40°C to 250°C

Dimensions:

2507 is considered a stock standard material for OSTP in selected production standards and dimension ranges.
