Manufacture, Heat Treatment & Weldability

Duplex 2507 piping materials can be manufactured by hot forming or cold forming methods. The hot forming temperature shall be between 1875°F and 2250°F. This should be followed by solution annealing at 1925°F minimum and a rapid air or water quench. The cold forming includes bending, deep drawing, extruding and pressing. After the cold forming process, the heat treatment of solution annealing and quenching is required. Besides, 2507 duplex stainless steels have good weldability.
