1.4104 (X14CrMoS17) Material Data Sheet

1.4104 is a rust- and acid-resistant martensitic chromium steel with added sulfur, which improves its machinability. However, despite the high chromium content, the corrosion resistance is reduced due to the sulfur.

1.4104 is also known under the classification AISI 430F.

Application areas

The main application of this material are in areas that cause pitting or crevice corrosion. In addition, due to its excellent machinability, the steel grade 1.4104 is used in the automotive industry, hydraulics and in the water and steam sector.

This stainless steel is also used in the manufacture of screws, axes, spindles and nuts and fittings.

Forging: special care must be taken when forging, as a ferritic-austenitic structure is created due to the high sulfur content. During forging the material is slowly heated to 850°C, and will be increase to 1,100°C - 1,130°C. The forging process takes place at 1,130°C and 750°C.

Welding: the 1.4104 is usually not welded. The mechanical-technological values ​​of the welding and the heat can affect be very different from the values of the base material without additional heat post-treatment.

Soft annealing: The soft annealing of the material takes place at 750°C to 850°C, with subsequent furnace or air cooling.

Corrosion resistance: Due to the high sulfur content, the corrosion resistance is impaired.

Cold forming: Cold forming is possible.

Hardening: The ferritic steel can be cured at 950°C to 1070°C. The subsequent cooling should take place in the media polymer, oil or air.

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.
