SAE 51431 | 1.4044 - Data sheet

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.
