BÖHLER P501 is a highly corrosion-resistant, nitrogen-strengthened Cr-Ni-Mo-N steel that is characterised by its resistance to corrosion in seawater and very good resistance to intergranular corrosion and stress corrosion cracking. Due to the alloy design, the yield strength is significantly higher than that of a comparable Cr-Ni-Mo stainless steels and a stable austenitic microstructure is achieved, so that the steel remains non-magnetisable even after cold forming and has the lowest magnetic permeability. In addition to its original application as a hull and structure for submarines, BÖHLER P501 is also used for magnetic shielding and components in the oil and gas industry, for example.
