SUPER DUPLEX STAINLESS STEEL SEAMLESS PIPES COLD ROLLED,SOLUTION ANNEALED PICKLED AND PASSIVATED,
CONFORMS TO ASTM A 790, UNS S 32760, SOUR SERVICES,

Features:
Avoid temperatures below -50°C because of its ductile-to-brittle-transition.
Easy to weld with excellent weldability.

High resistance to abrasion, erosion and cavitation erosion
Excellent resistance to stress corrosion cracking in chloride containing environments

SA-789:2205, 2507 Seamless & Welded (Duplex) Stainless Steel Tubing for General Service

Solution treatment (annealing) -heat to 1020ºC-1100ºC and cool rapidly. This grade cannot be hardened by thermal treatment, but does work harden.
