PRODUCTOS

430F 1.4104 is a ferritic, straight chromium alloy melted as AOD. This alloy is similar to 430 stainless with increased sulfur to dramatically improve machinability This alloy does not form as easily as standard 430 due to the sulfur but still has moderate ductility.

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

Chemical Composition

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.
