EFW Welded Stainless Steel Tube UNS S32750 A928M Round Mechanical Tubing
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.
