A335 / SA335 P91 Type 2 Chrome Moly Pipe
as well as Flanges, Fittings & Valves
Applied Alloys is Australia’s premier source for ASTM A335 / SA335 P91 Type 2 Chrome Moly Steel Pipe & WP-91 Fittings, F-91 Flanges, and Valves to suit.
A335 P91 Type 2 / UNS K91560 seamless ferritic alloy-steel pipe for high-temperature service. P91 provides extremely high creep strength and increased oxidation at high temperatures which allow for reduced wall thickness. P91 is suitable for bending, flagging, and similar forming operations and for fusion welding. Full lengths or cut to size for immediate shipping. Other Grades available: P5, P9, P11, P22, P92
