Product Description

BÖHLER P511 is a weldable, non-magnetic austenitic steel with resistance to seawater and intergranular corrosion. Does not require post-weld heat treatment. This austenitic stainless Cr-Ni-Mn-Mo-N steel has corrosion resistance greater than that provided by Cr-Ni-MoTypes 316, 316L, 317, and 317L, plus approximately twice the yield strength at room temperature. In addition, BÖHLER P511 Stainless Steel has very good mechanical properties at both elevated and subzero temperatures. Unlike many austenitic stainless steels it does not become magnetic when cold worked or cooled to sub-zero temperatures. BÖHLER P511 is especially suitable for cryogenic application thanks to its excellent impact strength at -196 °C (-320 °F).

Application
Oil and Gas, offshore, subsea, chemical, fertilizer, nuclear fuel recycling, pulp and paper, textile, food processing and marine industries. Components using the combination of excellent corrosion resistance and high strength include: pumps, valves and fittings, fasteners, cables, chains, marine hardware, boat and valves shafting, heat exchanger parts, and springs.

Property Features

Non-magnetic austenitic steel. Resistance to seawater and intergranular corrosion. Weldable. Does not require post-weld heat treatment.
