SAE 51431 | 1.4044
WL 1.4044.6 | Z15CN 17-03 hardened and tempered
SAE 51431 is a stainless steel containing about 16% chromium with additions of nickel and achieves high mechanical properties through a conventional arc melting process. Due to moderate corrosion resistance, SAE 51431 is used in areas with lower corrosive requirements but higher mechanical properties than those of 410 stainless steel.
Areas of application for SAE 51431 | 1.4546.9
Machine tool industry, aircraft fittings, pump shafts, valve components, bolts and screws and chemical equipment.
