Disclosed is an iron-manganese alloy including, by weight: 25.0%≤Mn≤32.0%; 7.0%≤Cr≤14.0%; 0≤Ni≤2.5%; 0.05%≤N≤0.30%; 0.1≤Si≤0.5%; and optionally 0.010%≤rare earths≤0.14%. The remainder being iron and residual elements resulting from manufacturing.

Iron-manganese alloy having improved weldability

A method for manufacturing a strip having a variable thickness along its length, comprising the steps: The plastic deformation ratio generated, after an optional intermediate recrystallization annealing, by the homogeneous cold rolling and the flexible cold rolling steps in the first areas is greater than or equal to 30%.

A device for orientating a sensor probe relative to the local normal vector of a work surface, the device comprising: a frame, a moving support element linked to the frame and able to slide in a predetermined direction, a sensor probe able to pivot on an axis of rotation not parallel to the predetermined direction relative to a point of articulation of the support element, pressure means able to move and generate a force on the moving support element in predetermined direction so as to press the sensor probe against the work surface, in which the sensor probe comprising a single convex external sensing surface suitable for being placed in contact with the work surface, the sensing surface having a single equilibrium contact point, the equilibrium contact point being the point on the sensing surface closest to the point of articulation.
