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.
Tubes, Pipes and Butt Weld Fittings
• OD: 21.3–1219.0 mm
• WT: 1.5–25.4 mm
• Lengths: up to 12 m
Tubes below 21.3 mm OD and tubes with wall thickness below 1.5 mm or length over 12 m on special request.
Standard Stock Dimension Range:
• ANSI NPS 6–12" Sch 10S, ASTM A928 Class 3
• Fittings according to ASTM A815
Executions:
Tubes, Pipes and Butt Weld Fittings
• Welded with- or without filler metal
• Unannealed, pickled
• Solution annealed and pickled
• With – or Without BCW (Bead Cold Work)
– Tubes Only
• Bevelled ends according to standards
