1.4057 (X17CrNi16-2) directly from stock & cut to your required dimensions
1.4057 is a corrosion and acid resistant martensitic chromium steel with nickel additive. The formation of chromium carbides and the associated chromium-depleted areas makes this material susceptible to intergranular corrosion.
1.4057 is popularly known as AISI 431.
Main application in mechanical engineering, as Pressure Disc, petroleum and petrochemical industry and aviation.
Machinability: 5 (1 = very bad - 10 = good)
Corrosion class: 2 (0 = weak - 5 = good)
flat, forged, quenched and tempered
The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting. Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
