BÖHLER P511
BÖHLER P511 is a weldable, non-magnetic, austenitic steel with resistance to seawater and intergranular corrosion.
This austenitic, stainless Cr-Ni-Mn-Mo-N steel has higher corrosion resistance than Cr-Ni-Mo grades 316, 316L, 317 and 317L and approximately twice the yield strength at room temperature. In addition, BÖHLER P511 has very good mechanical properties at both high and low temperatures. Unlike many austenitic stainless steels, it does not become magnetic when cold-formed or cooled to sub-zero temperatures. Thanks to its excellent notched impact strength at -196 °C (-320 °F), BÖHLER P511 is particularly suitable for low-temperature applications.
Typical applications are found in the oil and gas, chemical, fertilizer, paper, textile, food and marine industries for components requiring a combination of excellent corrosion resistance and high strength, e.g. pumps, valves and fittings, fasteners, cables, chains, ship fittings, boat and valve shafts, heat exchanger parts and springs.
