1.4541 (X6CrNiTi18-10) Material Data Sheet

The material 1.4541 is comparable to the steel grade 1.4878

1.4541 is used when resistance to intergranular corrosion is desired after welding. However, due to the titanium stabilization, the material tends to form lines and is thus affected by knife-edge corrosion.

This material is often replaced by steels with low carbon contents (less than 0.03%) for example the 1.4307, as they have the same corrosion resistance does not cause the above-mentioned disadvantages caused by titanium.

The chemical composition and properties are comparable with the material 1.4301.

Good corrosion resistance in natural environmental media (waters of rural and industrial atmosphere). The prerequisite is that chlorine and salt concentrations as well as concentration of nitric or organic acids are low.

The 1.4541 is also known under the classification AISI 321.

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.
