EN 1.4122 is a chromium martensitic stainless steel with molybdenum addition. IT is characterized by its outstanding post heat treatment mechanical properties and corrosion resistance which is comparable / better than grade 1.4016. It has chromium content up to 17% which contributes to its better corrosion resistance compare to 13% chromium grades such as the 1.4006.
Material may also be supplied against customer specifications, subject to enquiry.
Chemical Composition, %
The 1.4122 is corrosive resistant in media with low aggressiveness and low chlorine-ion concentration. Pitting susceptibility of the grade is lower due to the molybdenum additive. Polishing the surface will optimize the corrosion resistance. Welding is not usually done with this grade.
Weldability: not possible
Machinability: 5 (1 = poor – 10 = good)
Corrosion class: 2 – 3 (0 = poor – 5 = good)
We supply a range of flat bars and round bars, on both stock and indent basis.
Primarily manufactured in: Europe, US
